Lettuce infectious yellows virus: in vitro acquisition analysis using partially purified virions and the whitefly Bemisia tabaci. (1/301)

Virions of lettuce infectious yellows virus (LIYV; genus Crinivirus) were purified from LIYV-infected plants and their protein composition was analysed by SDS-PAGE and immunoblotting. Virion preparations contained the major capsid protein (CP), but the minor capsid protein (CPm), p59 and the HSP70 homologue were also identified by immunoblot analysis. Immunogold labelling analysis showed that CP constituted the majority of the LIYV virion capsid, but CPm was also part of the capsid and localized to one end of the virion, similar to the polar morphology seen for viruses in the genus Closterovirus. p59 and the HSP70 homologue were not detected on virions by immunogold labelling, but were always detected in virion preparations by immunoblot analysis. Purified LIYV virions were used for in vitro acquisition analysis with Bemisia tabaci whiteflies and were efficiently transmitted to plants. Infectivity neutralization analyses were done using antisera to the LIYV-encoded CP, CPm, p59 and HSP70 homologue. Only antiserum to the CPm effectively neutralized LIYV transmission by B. tabaci. These data suggest that the LIYV-B. tabaci transmission determinants are associated with purified virions, and that the LIYV virion structural protein CPm is involved in transmission by B. tobaci.  (+info)

Comparison of phylloquinone bioavailability from food sources or a supplement in human subjects. (2/301)

Phylloquinone (K) absorption was assessed in 22- to 30-y-old human subjects consuming a standard test meal [402 kcal (1682 kJ), 27% energy from fat]. The absorption of phylloquinone, measured over a 9-h period as the area under the curve (AUC), was higher (P < 0.01) after the consumption of a 500- microgram phylloquinone tablet [27.55 +/- 10.08 nmol/(L. h), n = 8] than after the ingestion of 495 microgram phylloquinone as 150 g of raw spinach [4.79 +/- 1.11 nmol/(L. h), n = 3]. Less phylloquinone (P < 0.05) was absorbed from 50 g of spinach (AUC = 2.49 +/- 1.11 nmol/(L. h) than from 150 g of spinach. Absorption of phylloquinone from fresh spinach (165 microgram K), fresh broccoli (184 microgram K) and fresh romaine lettuce (179 microgram K) did not differ. There was no difference in phylloquinone absorption from fresh or cooked broccoli or from fresh romaine lettuce consumed with a meal containing 30 or 45% energy as fat.  (+info)

A plant-derived edible vaccine against hepatitis B virus. (3/301)

The infectious hepatitis B virus represents 42 nm spherical double-shelled particles. However, analysis of blood from hepatitis B virus carriers revealed the presence of smaller 22 nm particles consisting of a viral envelope surface protein. These particles are highly immunogenic and have been used in the design of hepatitis B virus vaccine produced in yeast. Upon expression in yeast, these proteins form virus-like particles that are used for parenteral immunization. Therefore, the DNA fragment encoding hepatitis B virus surface antigen was introduced into Agrobacterium tumerifacience LBA4404 and used to obtain transgenic lupin (Lupinus luteus L.) and lettuce (Lactuca sativa L.) cv. Burpee Bibb expressing envelope surface protein. Mice that were fed the transgenic lupin tissue developed significant levels of hepatitis B virus-specific antibodies. Human volunteers, fed with transgenic lettuce plants expressing hepatitis B virus surface antigen, developed specific serum-IgG response to plant produced protein.  (+info)

Effects of green fluorescent protein or beta-glucuronidase tagging on the accumulation and pathogenicity of a resistance-breaking Lettuce mosaic virus isolate in susceptible and resistant lettuce cultivars. (4/301)

The RNA genome of a resistance-breaking isolate of Lettuce mosaic virus (LMV-E) was engineered to express the jellyfish green fluorescent protein (GFP) or beta-glucuronidase (GUS) fused to the helper-component proteinase (HC-Pro) to study LMV invasion and spread in susceptible and resistant lettuce cultivars. Virus accumulation and movement were monitored by either histochemical GUS assays or detection of GFP fluorescence under UV light. The GFP- and GUS-tagged viruses spread systemically in the susceptible lettuce cultivars Trocadero and Vanguard, where they induced attenuated symptoms, compared with the wild-type virus. Accumulation of the GFP-tagged virus was reduced but less affected than in the case of the GUS-tagged virus. Systemic movement of both recombinant viruses was very severely affected in Vanguard 75, a lettuce cultivar nearly isogenic to Vanguard but carrying the resistance gene mo1(2). Accumulation of the recombinant viruses in systemically infected leaves was either undetectable (GUS-tag) or erratic, strongly delayed, and inhibited by as much as 90% (GFP-tag). As a consequence, and contrary to the parental virus, the recombinant viruses were not able to overcome the protection afforded by the mo1(2) gene. Taken together, these results indicate that GUS or GFP tagging of the HC-Pro of LMV has significant negative effects on the biology of the virus, abolishing its resistance-breaking properties and reducing its pathogenicity in susceptible cultivars.  (+info)

A heterogeneous population of defective RNAs is associated with lettuce infectious yellows virus. (5/301)

Preparations of dsRNAs and virion RNAs extracted from Nicotiana clevelandii plants infected with the bipartite Lettuce infectious yellows virus (LIYV) were found to contain multiple LIYV RNA species. In addition to the two LIYV genomic RNAs, three types of RNAs were observed: (a) 3' coterminal subgenomic RNAs; (b) RNAs containing LIYV RNA 1 or RNA 2 5' terminus but lacking the 3' terminus; and (c) RNAs with both LIYV RNA 2 3' and 5' termini but each with a central extensive deletion, a structure typical of defective RNAs (D RNAs). No D RNA-like RNAs were detected for LIYV RNA 1. A reverse transcription followed by polymerase chain reaction (RT-PCR) strategy was used to clone from virion RNAs several LIYV RNA 2 D RNAs as cDNAs. Nucleotide sequence analysis of 43 cloned cDNAs showed in some D RNAs the presence of a stretch of 1-5 nt in the junction site that is repeated in the genomic RNA 2 in the two positions flanking the junction site or in close proximity. Some D RNAs contained in the junction site one or several extra nucleotides not present in the LIYV genomic RNA 2. Two of the cloned cDNAs were used to generate in vitro transcripts, and infectivity studies showed that both D RNAs were replication competent in protoplasts when coinoculated with LIYV RNAs 1 and 2 or with only LIYV RNA1. Neither D RNA showed obvious effects upon LIYV RNA 1 and RNA 2 accumulation in coinfected protoplasts. These data suggest that LIYV infections contain a heterogeneous population of LIYV RNA 2 D RNAs, and some are encapsidated into virions.  (+info)

Asynchronous accumulation of lettuce infectious yellows virus RNAs 1 and 2 and identification of an RNA 1 trans enhancer of RNA 2 accumulation. (6/301)

Time course and mutational analyses were used to examine the accumulation in protoplasts of progeny RNAs of the bipartite Crinivirus, Lettuce infectious yellow virus (LIYV; family Closteroviridae). Hybridization analyses showed that simultaneous inoculation of LIYV RNAs 1 and 2 resulted in asynchronous accumulation of progeny LIYV RNAs. LIYV RNA 1 progeny genomic and subgenomic RNAs could be detected in protoplasts as early as 12 h postinoculation (p.i.) and accumulated to high levels by 24 h p.i. The LIYV RNA 1 open reading frame 2 (ORF 2) subgenomic RNA was the most abundant of all LIYV RNAs detected. In contrast, RNA 2 progeny were not readily detected until ca. 36 h p.i. Mutational analyses showed that in-frame stop codons introduced into five of seven RNA 2 ORFs did not affect accumulation of progeny LIYV RNA 1 or RNA 2, confirming that RNA 2 does not encode proteins necessary for LIYV RNA replication. Mutational analyses also supported that LIYV RNA 1 encodes proteins necessary for replication of LIYV RNAs 1 and 2. A mutation introduced into the LIYV RNA 1 region encoding the overlapping ORF 1B and ORF 2 was lethal. However, mutations introduced into only LIYV RNA 1 ORF 2 resulted in accumulation of progeny RNA 1 near or equal to wild-type RNA 1. In contrast, the RNA 1 ORF 2 mutants did not efficiently support the trans accumulation of LIYV RNA 2. Three distinct RNA 1 ORF 2 mutants were analyzed and all exhibited a similar phenotype for progeny LIYV RNA accumulation. These data suggest that the LIYV RNA 1 ORF 2 encodes a trans enhancer for RNA 2 accumulation.  (+info)

Metabolite profiling of sesquiterpene lactones from Lactuca species. Major latex components are novel oxalate and sulfate conjugates of lactucin and its derivatives. (7/301)

Wounding leaves or stems of Lactuca species releases a milky latex onto the plant surface. We have examined the constituents of latex from Lactuca sativa (lettuce) cv. Diana. The major components were shown to be novel 15-oxalyl and 8-sulfate conjugates of the guaianolide sesquiterpene lactones, lactucin, deoxylactucin, and lactucopicrin. The oxalates were unstable, reverting to the parent sesquiterpene lactone on hydrolysis. Oxalyl derivatives have been reported rarely from natural sources. The sulfates were stable and are the first reported sesquiterpene sulfates from plants. Unusual tannins based on 4-hydroxyphenylacetyl conjugates of glucose were also identified. Significant qualitative and quantitative variation was found in sesquiterpene lactone profiles in different lettuce varieties and in other Lactuca spp. The proportions of each conjugate in latex also changed depending on the stage of plant development. A similar profile was found in chicory, in which oxalyl conjugates were identified, but the 8-sulfate conjugates were notably absent. The presence of the constitutive sesquiterpene lactones was not correlated with resistance to pathogens but may have a significant bearing on the molecular basis of the bitter taste of lettuce and related species. The induced sesquiterpene lactone phytoalexin, lettucenin A, was found in the Lactuca spp. but not in chicory.  (+info)

Contamination of foods by food handlers: experiments on hepatitis A virus transfer to food and its interruption. (8/301)

Hepatitis A virus (HAV) is an important pathogen which has been responsible for many food-borne outbreaks. HAV-excreting food handlers, especially those with poor hygienic practices, can contaminate the foods which they handle. Consumption of such foods without further processing has been known to result in cases of infectious hepatitis. Since quantitative data on virus transfer during contact of hands with foods is not available, we investigated the transfer of HAV from artificially contaminated fingerpads of adult volunteers to pieces of fresh lettuce. Touching the lettuce with artificially contaminated fingerpads for 10 s at a pressure of 0.2 to 0.4 kg/cm(2) resulted in transfer of 9.2% +/- 0.9% of the infectious virus. The pretreatments tested to interrupt virus transfer from contaminated fingerpads included (i) hard-water rinsing and towel drying, (ii) application of a domestic or commercial topical agent followed by water rinsing and towel drying, and (iii) exposure to a hand gel containing 62% ethanol or 75% liquid ethanol without water rinsing or towel drying. When the fingerpads were treated with the topical agents or alcohol before the lettuce was touched, the amount of infectious virus transferred to lettuce was reduced from 9.2% to between 0.3 and 0.6% (depending on the topical agent used), which was a reduction in virus transfer of up to 30-fold. Surprisingly, no virus transfer to lettuce was detected when the fingerpads were rinsed with water alone before the lettuce was touched. However, additional experiments with water rinsing in which smaller volumes of water were used (1 ml instead of 15 ml) showed that the rate of virus transfer to lettuce was 0.3% +/- 0.1%. The variability in virus transfer rates following water rinsing may indicate that the volume of water at least in part influences virus removal from the fingerpads differently, a possibility which should be investigated further. This study provided novel information concerning the rate of virus transfer to foods and a model for investigating the transfer of viral and other food-borne pathogens from contaminated hands to foods, as well as techniques for interrupting such transfer to improve food safety.  (+info)

The foodborne pathogen Listeria monocytogenes lives as a saprophyte in nature and can adhere to and grow on surfaces as diverse as leaves, sediment, and stainless steel. To discern the mechanisms used by L. monocytogenes for attachment and growth on various surfaces, we studied interactions between the pathogen on lettuce and stainless steel. A panel of 24 strains (23 L. monocytogenes and 1 Listeria innocua) were screened for attachment and growth on lettuce at 4 and 25°C and on stainless steel at 10 and 37°C. Overnight growth of attached cells resulted in a 0- to 3-log increase on lettuce, depending on the strain and the temperature. Among the worst-performing strains on lettuce were two from a large cantaloupe outbreak, indicating that factors important for interactions with cantaloupe may be different from those required on lettuce tissue. Strains that grew the best on lettuce belonged to serotypes 1/2a, 1/2b, and 4b and were from cheese, potatoes, and water-sediment near produce fields. ...

Abstract: One of the most important problems in horticultural seed science and technology nowadays is looking for new methods to improve seed quality. Especially interesting are the ones, in which compounds of natural origin are used. One of such groups is ethereal oils from plants. The commercial seed samples of lettuce (Lactuca sativa L. Dumka) were soaked in 9 different treatments of 5% alcoholic solution of camphor tree (Cinnamomum camphora L.) ethereal oil and 9 different treatments of 5% alcoholic solution of patchouli plant (Pogostemon cablin Benth.) ethereal oil. Then the seeds were routinely tested for seed germination, the length of the received seedlings was also measured and the seeds health status was evaluated. The tested ethereal oils had no effect on the germination of lettuce seeds. However, soaking the seeds in the ethereal oils solutions did decrease the percentage of dead seeds in the tested samples. Soaking of the seeds in the ethereal oils solutions also increased the ...

Lactuca serriola is the wild progenitor of cultivated lettuce (Lactuca sativa), and can be affected by lettuce downy mildew, one of the most serious diseases of lettuce.[15] L. serriola has shown resistance to the plant pathogen Bremia lactucae, the cause of the disease.[15] This pathogen is able to undergo sexual reproduction, and once virulent strains have been produced, can undergo rapid asexual reproductive cycles.[16] As a result, there are many strains, which vary in virulence.[16]. Resistance to Bremia lactucae in Lactuca serriola is due to Dm genes, or single dominant genes.[16] Nine of the dominant genes that confer resistance are Dml, Dm, Dm3, Dm6, Dml4, Dml5, DmlO, Dm5/8, Dm10, Dm4, Dm7, Dm11, and Dm13.[15] These genes are mapped in four linkage groups, so the genes within each group will be more likely to be inherited together.[15] Lactuca serriola and B. lactucae have a gene-for-gene relationship,[17] meaning that each resistance gene in the plant is associated with a specific gene ...
The canopy net photosynthesis (Pn) of lettuce (Lactuca sativa L. ev.Ambassador) was analyzed under controlled conditions simulating the winter glasshouse atmosphere. Prior to measurements the plants were grown in CO2-enriched air of 1000 μmol mol−1, at a photosynthetic photon flux density (PPFD) of 280 μmol m2 s−1 (400-700 nm) and a day/night air temperature of 16/13 °C. Short-term changes in CO2 concentration significantly changed the initial gradient of the photosynthetic response to incident PPFD. Maximum photosynthetic efficiency of the crop increased from 0·041 mol CO2 mol photons−1 (equivalent to 8·2 μg CO2 J−1 and 9·4% on an energy basis) at 350 μmol mol−1 to 0·055 mol CO2 photons−1 (10·9 μg CO2 J−1 and 12·7% on an energy basis) at 1000 μmol mol−1. Transfer from low to high CO2 also lowered the light compensation point, but did not affect dark respiration. The large response of Pn to transient changes in CO2 indicated that the lettuce canopy did not ...

Lettuce (Lactuca sativa L.) is a popular vegetable that is widely grown and consumed throughout the world. China is the largest producer of lettuce, contributing 55% to the worlds total production by weight. By contrast, the United States contributes only about 16% to total lettuce production worldwide. The primary type of lettuce produced and consumed in China is a stem lettuce (L. sativa L. var. angustana), while in the U.S. there are three main lettuce types produced: iceberg (L. sativa L. var. capitata), romaine (L. sativa L. var. longifolia), and leaf (L. sativa L. var. crispaa). These three lettuces account for 54.1%, 30.1%, and 15.8% of U.S. production, respectively.(40). Lettuce comes in a variety of colors, sizes and shapes. Romaine lettuce is exceptionally crisp, slightly bitter, and is characterized by long, narrow leaves with thick ribs. In addition, the leaves are typically upright to form an elongated head (top of the head may or may not close over the inner leaves) with ...

Phytochrome regulates lettuce (Lactuca sativa L. cv. Grand Rapids) seed germination via the control of the endogenous level of bioactive gibberellin (GA). In addition to the previously identified LsGA20ox1, LsGA20ox2, LsGA3ox1, LsGA3ox2, LsGA2ox1, and LsGA2ox2, five cDNAs were isolated from lettuce seeds: LsCPS, LsKS, LsKO1, LsKO2, and LsKAO. Using an Escherichia coli expression system and functional assays, it is shown that LsCPS and LsKS encode ent-copalyl diphosphate synthase and ent-kaurene synthase, respectively. Using a Pichia pastoris system, it was found that LsKO1 and LsKO2 encode ent-kaurene oxidases and LsKAO encodes ent-kaurenoic acid oxidase. A comprehensive expression analysis of GA metabolism genes using the quantitative reverse transcription polymerase chain reaction suggested that transcripts of LsGA3ox1 and LsGA3ox2, both of which encode GA 3-oxidase for GA activation, were primarily expressed in the hypocotyl end of lettuce seeds, were expressed at much lower levels than the ...

Cultivated lettuce (Lactuca sativa L.) and wild L. serriola L. differ greatly in both shoot and root characteristics. Approximately 100 F(2:3) families derived from an interspecific cross were evaluated in greenhouse and field experiments. In the greenhouse, root traits (taproot length, number of laterals emerging from the taproot, and biomass) and shoot biomass were measured 4 weeks after planting. In the field, plants were ...
3. Carotenoids. Carotenoids are antioxidants which protect your cells from damage. Carotenoids are especially important for the health and protection of your eyes. Romaine lettuce specifically contains the carotenoids lutein and zeaxanthin. These carotenoids are thought to prevent ocular diseases such as Macular Degeneration. Additionally, the carotenoid nutrition found in romaine lettuce can also reduce some of the adverse effects of smoking (if you were formerly a smoker). Carotenoids can repair damaged tissue.. 4. Vitamin C. Vitamin C is a powerful antioxidant. Romaine lettuce contains 24mg of vitamin C per serving. This essential antioxidant found in romaine lettuce protects your body from foreign invaders and promotes healthy tissue growth. In addition to strengthening your immune system, vitamin C is thought to reduce inflammation in the body and increase your pain threshold. This is especially important if you are an athlete and/or suffer from chronic pain.. 5. Saponins. Saponins are ...
TY - JOUR. T1 - The disease resistance gene Dm3 is infrequent in natural populations of Lactuca serriola due to deletions and frequent gene conversions at the RGC2 locus. AU - Kuang, Hanhui. AU - Ochoa, Oswaldo E.. AU - Nevo, Eviatar. AU - Michelmore, Richard W. PY - 2006/7. Y1 - 2006/7. N2 - Resistance genes can exhibit heterogeneous patterns of variation. However, there are few data on their frequency and variation in natural populations. We analysed the frequency and variation of the resistance gene Dm3, which confers resistance to Bremia lactucae (downy mildew) in 1033 accessions of Lactuca serriola (prickly lettuce) from 49 natural populations. Inoculations with an isolate of Bremia lactucae carrying avirulence gene Avr3 indicated that the frequency of Dm3 in natural populations of L. serriola was very low. Molecular analysis demonstrated that Dm3 was present in only one of the 1033 wild accessions analysed. The sequence of the 5′ region of Dm3 was either highly conserved among ...

Identification and screening of cultivars rich in bioactive phytoconstituents can be potentially useful to make nutrient-dense dishes and in medicinal formulations. In this study, we have identified, characterized and quantified caffeoylquinic acids, dicaffeoylquinic acid, dicaffeoyltartaric acid, kaempferol conjugates, quercetin malonylglucoside, sesquiterpene lactones, and cyanidin in 22 lettuce cultivars at mature and bolting stages using UPLC-PDA-Q-TOF-HDMS, UPLC, and HPLC. The composition and contents of the studied metabolites and antioxidant activity varied significantly and depend on leaf color, cultivar type and stage of maturity. The main phenolic acid components of lettuce were quinic and tartaric acid derivatives, whereas kaempferol derivatives were the dominant flavonoids. The sum of the content of phenolic acids ranged from 18.3 to 54.6 mg/100 g DW and 15.5 to 54.6 mg/100 g DW, whereas the sum of the contents of flavonoids ranged from 9.2 to 25.9 mg/100 g DW and 14.9 to 83.0 mg/100 g DW in

In a hilarious piece in yesterdays New York Sun, Paul Lukas discovers that some fancy-pants chefs love iceberg lettuce, too. Im not ashamed to admit that I love iceberg lettuce. Its cool, its crisp, and its a perfect foil for blue cheese dressing. Dont get me wrong. I love a fresh, peppery arugula salad picked that morning from somebodys garden. But I dont much care for wilted organic arugula grown 3,000 miles from my house and picked two weeks before it finds its way into my hands. I also hate iceberg lettuce that is more brown than light green with tons of droopy outer leaves. Cmon, admit it. You like iceberg lettuce, too. Heres a great blue cheese dressing...
Glycine, the simplest amino acid in nature and one of the most abundant free amino acids in soil, is regarded as a model nutrient in organic nitrogen studies. To date, many studies have focused on the uptake, metabolism and distribution of organic nitrogen in plants, but few have investigated the nutritional performance of plants supplied with organic nitrogen. Lettuce (Lactuca sativa L.), one of the most widely consumed leafy vegetables worldwide, is a significant source of antioxidants and bioactive compounds such as polyphenols, ascorbic acid and tocopherols. In this study, two lettuce cultivars, Shenxuan 1 and Lollo Rossa, were hydroponically cultured in media containing 4.5, 9, or 18 mM glycine or 9 mM nitrate (control) for 4 weeks, and the levels of health-promoting compounds and antioxidant activity of the lettuce leaf extracts were evaluated. Glycine significantly reduced fresh weight compared to control lettuce, while 9 mM glycine significantly increased fresh weight compared to 4.5 or 18 mM
February 12, 2007. Iceberg lettuce ranks as one of Americas top-five favorite veggies. However, this delicately flavored, slightly sweet crisphead and its relatives the romaine of Caesar salads, the softer textured leaf lettuces, or the creamy butterheads like Boston and bibb are vulnerable to attack by an impressive array of stealthy viruses and other natural enemies. But five kinds of superior iceberg lettuces, developed several years ago by Edward J. Ryder of the Agricultural Research Service (ARS), are today still holding their own against attack by two of these daunting villains: big vein virus and lettuce mosaic virus. A world-renowned lettuce breeder, Ryder, now retired, did the work while based at the ARS Crop Improvement and Protection Research Unit in Salinas, Calif.. In 2004, the plants became the first publicly available iceberg lettuces to boast resistance to both diseases. Thats why lettuce breeders and seed companies in California and elsewhere were quick to request samples of ...
d on magainin 2, an antimicrobial peptide from the African clawed toad, into lettuce in an attempt to enhance disease resistance. Magainin 2 was found to be non-toxic to lettuce seedlings in vitro at 50 µg/ml. In vitro experiments indicated that magainin was toxic to three important pathogens of lettuce, Erwinia carotovora subsp. carotovora (causal agent of soft rot), Pseudomonas marginalis (causal agent of soft rot) and Xanthomonas campestris pv. vitians (responsible for leaf spot of lettuce). Preliminary studies suggested that three fungal lettuce pathogens, Sclerotinia minor (causal agent of lettuce drop), S. sclerotiorum (causal agent of lettuce drop) and Botrytis cinerea (responsible for Botrytis and grey mold), were insensitive to magainin at 50 µg/ml. Transformation of lettuce was attempted using Agrobacterium strain AGLI containing the binary vector pBINMgA, and Agrobacterium strain EHA105 carrying either binary vector pBINMgB, pBINMgC or pBINMgD. These vectors each encoded one of four ...
Citation: Mccreight, J.D. 2005. New sources of lettuce aphid resistance in lettuce. Hortscience 40(4) p. 1109. Interpretive Summary: N/A Technical Abstract: Lettuce aphid (Nasonovia ribisnigri Mosley) is a recent insect pest to lettuce (Lactuca sativa L.) production in the U.S. The single dominant gene, Nr, conditions resistance to the lettuce aphid in Lactuca virosa accession IVT280 from The Netherlands and is available in a limited number of commercial lettuce cultivars. New and genetically unique sources of resistance are sought to broaden the genetic base for resistance to the lettuce aphid. Approx. 1200 lettuce PI lines were evaluated for resistance to lettuce aphid in greenhouse tests using a strain of lettuce aphid obtained from commercial lettuce in Salinas Valley, Calif. In 2002, plants were individually infested with five 24-hr nymphs per plant (controlled protocol), and the numbers of aphids per plant were counted 10 to 14 days post-infestation (dpi). Beginning in 2003, plants were ...
More Grocery Stores Pulling Romaine Lettuce Off Shelves. More and more grocery stores across the country are pulling romaine lettuce off their shelves.. It comes after the Public Health Agency of Canada asked those living in Ontario and Quebec to stay away from the lettuce until more is known about an E.coli outbreak and. what caused it. Stores that have pulled the lettuce include Zehrs and the Real Canadian Superstore in Ontario, No Frills in Alberta and Your Independent in B.C.. Canada Post Employees Could Be Legislated Back To Work.

Resistance to ALS-inhibiting herbicides in Lactuca serriola first appeared in the northern Yorke Peninsula in South Australia in 1994, with resistance soon observed at a number of additional sites. The rapid appearance of resistance at many sites could be attributed to a number of independent selection events or to movement of resistant seed from the original field. ISSRs were used to genotype plants collected in 1999 and 2004 from roadsides or fields in an attempt to determine the importance of these two factors in the spread of herbicide resistance in L. serriola. In 1999 and 2004, chlorsulfuron-resistant L. serriola plants were found in both fields and roadsides with resistant plants being more frequent in fields than roadsides and more frequent in 2004 than in 1999. Genetic relationships generated using UPGMA analysis indicated the presence of more than one genotype within the herbicide resistant populations sampled for both years and suggested independent selection as well as movement of ...
by: Rob Santich MNHAA. Since its development from wild species, the lettuce in all its ingredient. It is thought that the first cultivated crop varieties has become the worlds most popular salad originated in or around the Mediterranean basin. The supporting evidence for this is the existence of a transitional, nearly wild species of lettuce. The morphology of this nearly wild species indicates that it originates from Lactuca serriola, commonly called pricking lettuce, in reference to the bristly stems and leaf margins. Cooking oil is extracted from the seeds of Lactuca serriola to this day, as it was in ancient Egypt. The second piece of compelling evidence is found in the tombs of the ancient Egyptians.. Archaeologists have discovered tomb paintings of bundles of prickly lettuce and these have been dated to be 4,500 years old1.. The first written records of lettuce cultivation and consumption was by the first ancient Greek historian, Herodotus. He recorded that lettuce appeared on the tables ...

After nearly three months, the romaine lettuce outbreak appears to be over, federal health officials announced Wednesday. The Centers for Disease Control and Prevention said in an updated food safety report that it is no longer advising that people avoid romaine lettuce from the Salinas Valley growing region in California. Since Nov. 22, the CDC and the Food and Drug Administration have told consumers to avoid the lettuce from California as they investigated multistate E. coli
The prickles on the leaves are somewhat soft and incapable of cutting skin. Also, archaeobotanical evidence in Greek archaeological contexts is scanty, although uncarbonised seeds have been retrieved from a 7th-century BC deposit in a sanctuary of Hera on Samos. It is the closest wild relative of cultivated lettuce (Lactuca sativa L.). We are not health professionals, medical doctors, nor are we nutritionists. As the plant matures it increases in bitterness, becoming inedible by the time it produces flowers. Habitats include abandoned fields, fence rows, areas along railroads and roadsides, vacant lots, dumps, and miscellaneous waste areas. [23][26] There is especially high diversity within the Mediterranean area and Southwest Asia, but L. serriola has established populations on all continents and has the most widespread distribution compared to other Lactuca species. It can cause pulmonary emphysema in cattle feeding exclusively on the plant. This one, Prickly Lettuce, grows as a single stem. ...
America tries to eat its vegetables, so the recent romaine lettuce E. coli outbreak has put everyone from Caesar salad fans to those who barely tolerate a splash of greens in a taco on high alert. But how did these seemingly innocent little leaves turn hazardous? The Centers for Disease Control and Prevention has tallied 40 cases in 16 states stemming from the romaine lettuce grown in the Salinas, California, region, including 28 hospitalizations.

Agricultural managers are continually looking for ways to increase production while at the same time reduce costly inputs. One such way is an integration of two or more crops or production systems. Sustainability is a key word in our world today and one component of sustainability is the reduction of waste and the reuse of all available resources and refuse. Aquaponics is the combination of plant production and fish production whereby the byproducts of one system are used as an input for the other, thereby creating a symbiotic effect. One such system that has been used and shows promise is the combination of intensive production of tilapia (Oreochromis spp) and greenhouse production of lettuce (Lactuca sativa L.). Monoculture systems have traditionally relied on proven methods and inputs. However, in cross-cultural systems, what has proven to be standard practice for one production system may actually be harmful to the other production system. In intensive tank culture of fish, it is a common ...
Most lettuce leaves are green, but some are red. Most lettuce leaves taste bitter. Some kinds of lettuce grow in a head shape like cabbage, while the leaves of some kinds grow more loosely.. The five main cultivars are: green leaf, red leaf, cos, crisphead, and stem lettuce.[2]. Common varieties are Romaine, iceberg, and butter lettuce.. The name of the plant in English, lettuce, and in Latin, lactuca, come from lactis, the Latin word for milk, because the juice of the plant looks like milk.. ...
Lettuce (Lactuca sativa) is an annual plant of the daisy family, Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, the woju, or asparagus lettuce (celtuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. World production of lettuce and chicory for calendar year 2013 was 24.9 million tonnes, over half of which came from China. Lettuce was first cultivated by the ancient Egyptians who turned it from a weed whose seeds were used to produce oil, into a food plant grown for its succulent leaves

Author(s): Huo, Heqiang; Henry, Isabelle M; Coppoolse, Eric R; Verhoef-Post, Miriam; Schut, Johan W; de Rooij, Han; Vogelaar, Aat; Joosen, Ronny VL; Woudenberg, Leo; Comai, Luca; Bradford, Kent J | Abstract: Lettuce (Lactuca sativa) seeds exhibit thermoinhibition, or failure to complete germination when imbibed at warm temperatures. Chemical mutagenesis was employed to develop lettuce lines that exhibit germination thermotolerance. Two independent thermotolerant lettuce seed mutant lines, TG01 and TG10, were generated through ethyl methanesulfonate mutagenesis. Genetic and physiological analyses indicated that these two mutations were allelic and recessive. To identify the causal gene(s), we applied bulked segregant analysis by whole genome sequencing. For each mutant, bulked DNA samples of segregating thermotolerant (mutant) seeds were sequenced and analyzed for homozygous single-nucleotide polymorphisms. Two independent candidate mutations were identified at different physical positions in the
Small plot studies were conducted from 1999-2001 to examine the population abundance and control of the lettuce aphid on winter and spring head lettuce crops. In each year, Seven, 0.25 acre planting of head lettuce were established beginning in Sep-Oct with final harvest occurring in April. Replicated plots within several planting were treated with an Admire treatment at planting, a side dress application of Platinum post-planting or allowed to remain untreated. Lettuce aphids were first detected in our experimental area in December in PD 3 in 2001, but in 2002 first occurred in lettuce almost 2 months later (Feb 21). Similarly, lettuce aphid abundance was much greater in 2001 than in 2002, probably a result of temperature difference. Temperature had an important influence upon lettuce aphid development based on our field observations. Population appeared to increase in early March when the average daily temperature was about 65 E F. We observed a sharp decline in population abundance in April ...

Fresh leafy greens like lettuce can be consumed raw and are susceptible to foodborne pathogens if they become contaminated. Recently, the number of reported pathogenic foodborne outbreaks related to leafy greens has increased. Therefore, it is important to try to alleviate the human health burden associated with these outbreaks. Processing of fresh-cut lettuce, including washing, is a step in the supply chain that needs to be well controlled to avoid cross-contamination. Current measures to control the quality of lettuce during washing include the use of chemicals like chlorine; however, questions regarding the safety of chlorine have prompted research for alternative solutions with peracetic acid (PAA). This study evaluates the effectiveness of a PAA (c.a. 75 mg/L) solution on the reduction of a commensal E. coli strain during the washing of fresh-cut lettuce. Experiments were performed at the laboratory scale and validated at the industrial scale. We observed that the use of PAA was not ...
Romaine lettuce has been determined to be the likely source of an E. coli outbreak in Miramichi in April that caused more than 20 people to get sick.
Bacteria of the faba bean (Vicia faba L.)/Orobanche spp. root environment were evaluated for their potential use as biocontrol agents for the parasitic weed. Bacteria were isolated mainly from the rhizosphere of faba bean as well as from diseased Orobanche underground structures and an Orobanche -suppressive soil from three districts of northern Tunisia. Out of 351 bacterial isolates, 337 were tested for pathogenicity in an inverted pyramidal-shape screening programme including a Lactuca sativa L. seedlings bioassay, root-chamber and pot experiments. In preselection screening on L. sativa seedlings, 37 isolates (11%) showed a strong growth inhibitory effect, of which 70 and 84% also had a significant suppressive activity on the pre-emergence structures of O. foetida and O. crenata, respectively, in root-chamber experiments. Among five bacterial isolates selected for pot trials, strain Bf7-9 of Pseudomonas fluorescens showed high biocontrol activity against both species of Orobanche and ...
Pseudomonas cichorii is a Gram-negative soil bacterium that is pathogenic to plants. It has a wide host range, and can have an important economical impact on lettuce, celery and chrysanthemum crops. P. cichorii was first isolated on endives (Cichorium endivia), from which it derives its name. It produces 6-aminopenicillanic acid. Based on 16S rRNA analysis, P. cichorii has been placed in the P. syringae group. Pseudomonas cichorii is non-host specific as it does not infect just one host. Its host range includes lettuce, pepper, celery, coffee, wheat, basil and several other host plants. Symptoms of the causal agent vary depending on the host and the area of the plant infected. In general, pseudomonas cichorii is seen to cause leaf blighting and spotting. The first appearance of symptoms involves a water soaked lesion that develops at the edge of the leaf, midvein or randomly across the leaf These lesions progressively turn black or brown and may be surrounded by yellow halos. These lesions also ...
Increases longevity - Though sea lettuce is consumed worldwide, it is especially popular in Okinawan in Japan and Crete in Greece. Perhaps it is coincidental, but the residents of these two locations are well-known for their longevity. The Okinawa Centenarian Study, for example, found that the residents of Okinawa are 82 percent less likely than the average American to suffer from coronary heart disease. Moreover, a study published in the September 2008 edition of the British Medical Journal found that the morality rate of those who favor a Mediterranean diet is nine percent lower than those who favor the standard Western diet. Seafood - including sea vegetables like sea lettuce - dominate the diets of these people, so it is possible that these mineral-rich foods are responsible for such long-term healthfulness.. Rich in vitamins - Nutrition-wise, sea lettuce almost covers the entire vitamin spectrum. 100 grams of this green seaweed provide us with 221 micrograms of vitamin A, 10 milligrams of ...

The salad bed is thriving. Lettuces, onions, radishes are enjoying the cooler weather - so am I. Everything was fertilized this past weekend. Irrigation occurs about every other day. Its so nice not to have to get up at dark:30 and irrigate. I was getting out there and misting everything around 5:30. Now an occasional watering using the drip line does the trick.. Im harvesting the lettuce by pulling the lowest leaves as needed and allowing the rest of the plant to remain and grow. So far so good. As the onions are thinned they are chopped and used like chives. Since it freezes around here in December, this bed will be covered by a covered wagon type device with the hope that the lettuce and company will continue to provide salad throughout the winter.. A head of lettuce in the grocery store is ~$2. A packet of seeds cost slightly more at ~$2.50. Each packet contains ~250 seeds. At $0.01 a head for home grown nutritious lettuce its well worth growing your own. Sure theres the costs of water, ...
