The researchers used a well-characterized transgenic mouse that expresses a mutant gene present in humans and forms Alzheimers plaques (similar to the ones found in humans) in the brain starting at about 11 to 12 months. One group of mice received vitamin E at five months, before plaques start to form. Another group started at 14 months--a time when much plaque had already been deposited--with the same amount of vitamin E. They followed each group for eight months and compared their outcome with controls that did not receive vitamin E. The young group showed a 50 percent reduction in the number of plaques deposited in brain tissue as compared to the older mice. This group didnt show any significant difference in plaque reduction as compared to controls, suggesting that once the plaque is deposited theres very little that an antioxidant can do, says Praticò. This finding also indicates that other mechanisms may play a role in the disease once established ...

Rice dwarf mutants d61-1 and d61-2 were obtained independently by mutagenesis with N-methyl-N-nitrosourea (Figure 1B). These were initially characterized as two independent mutants, because the culm of d61-2 is much shorter than that of d61-1. In addition, d61-1 shows a typical dm-type pattern of internode elongation, whereas d61-2 shows the d6-type (Figure 1C). However, crosses between these mutants demonstrated that they are alleles of a single locus. To our knowledge, this is the only case of rice mutants of a single locus that show different, specific patterns of inhibition of internode elongation.. The phenotypes of these mutants are abnormal in other respects. For example, the neck internode of the mutants is longer than that of wild-type plants (Figure 1D). The neck internode length shows an inverse relationship to the length of culm in these plants, such that wild-type plants have the longest culm and shortest neck internode, the d61-1 mutant has intermediate length culm and neck ...

This article reveals impact of lodging on wheat productivity and quality. Significant yield reduction has been recorded in past few years only due to lodging. Hence, identification of potential plant traits is required to assist breeding programmes to release lodging tolerant high yielding wheat varieties. Standardization of agronomic practices can also contribute significantly to avoid crop lodging.
Plant architecture attributes, such as plant height, ear height, and internode number, have played an important role in the historical increases in grain yield, lodging resistance, and biomass in maize (Zea mays L.). Analyzing the genetic basis of variation in plant architecture using high density QTL mapping will be of benefit for the breeding of maize for many traits. However, the low density of molecular markers in existing genetic maps has limited the efficiency and accuracy of QTL mapping. Genotyping by sequencing (GBS) is an improved strategy for addressing a complex genome via next-generation sequencing technology. GBS has been a powerful tool for SNP discovery and high-density genetic map construction. The creation of ultra-high density genetic maps using large populations of advanced recombinant inbred lines (RILs) is an efficient way to identify QTL for complex agronomic traits. A set of 314 RILs derived from inbreds Ye478 and Qi319 were generated and subjected to GBS. A total of 137,699,000
HAILED SOYBEANS MAY COMPENSATE BUT WATCH FOR DISEASE. Yield loss in soybeans is determined on the stage of growth of the soybeans at the time of damage and the degree of plant damage. Damage can be due to leaf defoliation, stand reduction, stem damage and pod damage. The calendar date and pest control later also affect ultimate yield.. Check stands 7-10 days after a storm to determine the stand reduction. Determine the current stand versus the original stand. Count these losses as total losses if the plants are totally damaged below the cotyledons. Shredded or cut stems may lead to bruised plant stems. Mild bruising may only break in the outer stem tissue but severe bruising may expose the central stem tissue and lead to more loses. Unfortunately, bruised stems that recover may break any time before harvest as they are weakened. They may lodge and make harvest very difficult. It is very difficult to determine yield loss from bruised plants until harvest.. Defoliation is a measure of the leaf ...

Banking sources back in February 2015 told this author that the cards compromised in this most recent incident looked like they were stolen from many of the same White Lodging locations implicated in the 2014 breach, including hotels in Austin, Texas, Bedford Park, Ill., Denver, Indianapolis, and Louisville, Kentucky. Those sources said the compromises appear once again to be tied to hacked cash registers at food and beverage establishments within the White Lodging run hotels. The sources said the fraudulent card charges that stemmed from the breach ranged from mid-September 2014 to January 2015.. In a press release issued April 8, 2015, White Lodging announced the suspected breach of point of sales systems at food and beverage outlets, such as restaurants and lounges, from the period July 3, 2014 through February 6, 2015 at 10 properties.. While it acknowledged some of the locations breached this time around were the same as last years victim locations, the company emphasized that this was a ...

Traditionally rice straw has been considered a waste or by-product of growing rice, often being burnt in order to prepare for the next crop. The practice of burning rice straw is becoming environmentally unacceptable; hence many rice farmers are now seeking out more environmentally sustainable options to remove the straw from their paddocks that is also offering another source of income from their crop.. Rice straw can be a very economical feed option in the livestock growers toolbox if conserved properly and used wisely as a part of a feed ration. While it must be noted that rice straw is the lowest nutritional value form of straw available, not all rice straws are equal. There can be some very big differences in the quality of rice straw solely due to the timing of when the straw is harvested and baled. The sooner the rice straw is cut behind the header, the better the quality of the final product.. Ideally rice straw should be harvested between three to 10 days, post stripping with the ...
Yellow top borer caterpillars kill the plant growing points and cause dead hearts (the youngest still unfolded leaves wilt and die), broken stalks and reduced sugar contents in infested sugarcane crops (Figure 3). They can cause white heads (empty or partially filled heads of discoloured grain) in infested rice crops.. The tunnels inside the plant stems allow other pests and diseases into the infested stalks which can also increase crop losses. Infested plant stems are easily broken by wind.. Young sugarcane crops up to 10 weeks old are preferred by the caterpillars, which can kill the plant growing points within 12-18 days of entering the plant stems. Yellow top borer caterpillars can cause 30-75% yield losses in sugarcane crops in India. ...

An apparatus which includes a growing container in which plants are hydroponically grown on a support medium is disclosed. The growing container includes a plurality of openings in which seals are installed. The seals include holes through which the plants grow. When seeds are planted, a hollow tube is placed through the seal hole to maintain the seed in position. After the seed germinates, it grows through the tube. As continued growth expands the plants stem to the size of the tube, the tube breaks apart and does not constrain future plant growth. Moreover, as the plant grows further, the seal hole expands to accommodate the plant stem. The seal surrounds and contacts the plant stem to reduce evaporation of nutrient solution from the growing container and to keep insects and contamination out of the growing container. A holding container is positioned above the growing container and coupled to the growing container through a manifold arrangement. The holding container may be quickly filled with a
SW 5512Y is a high yielding medium recovery type suited for hay and haylage production where moderate speed of regrowth initiation is desired after cutting. As a lodging tolerant variety, SW5512Y is especially well-suited to growing situations that may lead to lodging. Compared to other varieties, SW5512Y can exhibit reduced lodging in situations of heavy manure application, irrigation from overhead sprinklers, or rain that leads to harvest delays and increased lodging potential, especially when accompanied by wind.. The first cut is the heaviest cutting of the year, and most susceptible to lodging. The lodging tolerant characteristic of SW5512Y helps maintain yield of the heavy first cut, and can help maintain forage quality of second and later cuttings through the reduction of long trailing uncut stems that often remain after cutting a lodged crop. Such uncut stems become less digestible, leading to forage quality reduction if harvested in subsequent cuttings. ...

Plant stems vascular tissues distribute substances to and from roots, leaves and other plant parts. Dicot stems have vascular bundles arrayed as a cylinder that separates the ground tissue into cortex and pith; whilst monocot stems have vascular bundles distributed throughout the ground tissues. The photosynthetic parenchyma cells are located between the upper and lower epidermis layer of leaves, whit abundant air spaces surrounding them. Plentiful openings, or stomata, in the lower epidermal layer allow water vapour and gasses to move across the waxy cuticle ...
Plant stems grow through a process of elongation due to cell divisions within the stem. Does the entire length of the stem elongate evenly? Or do certain regions along the plant stem grow more or less than others? Regions that are involved in active growth are called vegetative. You can conduct an experiment to show which regions of a bean seedling are involved in vegetative growth. Use a marker to mark one inch sections along the main stem of a young bean seedling. Number the regions 1-6 along the stem from the root to the shoot. Keep a daily log by measuring each region along the stem for a week or so. Do any of the regions elongate? Which regions show the most elongation? Which regions show the least elongation? What do you think would happen if you tried the same experiment with another species? What if you tried it with an older more mature plant? Will light or temperature effect the rate of growth? (VanCleave, 1993, 69-74; Vecchione, 2001, 150-151 ...

The first thing youll probably hear when it comes to saving some bucks on road trip lodging is go camping! But not all families are into the outdoors, and youre just asking for bad attitudes if you go Clark Griswold and try to force them into it. If your husband and kids are nature challenged, then a hotel will probably be more to more to their liking. Roadside motels usually have great rates, but if your family refuses to camp, they may also boycott the meager accommodations of a roach motel.. Just like with meals, planning for your hotel stays is a must. Plot your stops ahead of time and try to stick to that schedule. Once you know your stayover points, use the Internet to find discounted deals.

Herbaceous peony (Paeonia lactiflora Pall.) is a traditional famous flower, but its poor inflorescence stem quality seriously constrains the development of the cut flower. Mechanical strength is an important characteristic of stems, which not only affects plant lodging, but also plays an important role in stem bend or break. In this paper, the mechanical strength, morphological indices and microstructure of P. lactiflora development inflorescence stems were measured and observed. The results showed that the mechanical strength of inflorescence stems gradually increased, and that the diameter of inflorescence stem was a direct indicator in estimating mechanical strength. Simultaneously, with the development of inflorescence stem, the number of vascular bundles increased, the vascular bundle was arranged more densely, the sclerenchyma cell wall thickened, and the proportion of vascular bundle and pith also increased. On this basis, cellulose and lignin contents were determined, PlCesA3, PlCesA6 and

Peroxidases have been shown to be involved in the polymerization of lignin precursors, but it remains unclear whether laccases (EC 1.10.3.2) participate in constitutive lignification. We addressed this issue by studying laccase T-DNA insertion mutants in Arabidopsis thaliana. We identified two genes, LAC4 and LAC17, which are strongly expressed in stems. LAC17 was mainly expressed in the interfascicular fibers, whereas LAC4 was expressed in vascular bundles and interfascicular fibers. We produced two double mutants by crossing the LAC17 (lac17) mutant with two LAC4 mutants (lac4-1 and lac4-2). The single and double mutants grew normally in greenhouse conditions. The single mutants had moderately low lignin levels, whereas the stems of lac4-1 lac17 and lac4-2 lac17 mutants had lignin contents that were 20 and 40% lower than those of the control, respectively. These lower lignin levels resulted in higher saccharification yields. Thioacidolysis revealed that disrupting LAC17 principally affected ...

1.Piper arieianum, an evergreen, understorey shrub of lowland moist forests of Central and South America, exhibits marked seasonal variation in reproductive activity even though climatic variation is low at the study site. Despite a lack of climatic seasonality, previous experimental leaf removal suggested that carbohydrate accumulation is seasonal, occurring prior to flowering.. 2. We first tested the hypothesis that carbohydrates necessary for reproduction are accumulated prior to flowering, rather than during or after. By measuring non-structural carbohydrate production in the form of glucose and starch we found that the concentration of these reserves is greatest 1-3months before flowering, decreasing by 50% during peak fruit maturation.. 3. The hypothesis that reproduction was the cause of this decrease in carbohydrate reserves was then tested by comparing reserves in plants that were prevented from flowering with those that flowered and produced fruit naturally. As predicted, reserves ...
Secondary growth in diocts is due to the formation of two types of cambia, the vascular and cork cambia. The vascular cambium forms out of the fascicular cambium which lies between the primary xylem and phloem in the vascular bundles and the de-differentiation of the interfascicular parenchyma into a cambial group of cells. These two cambia then unite and produce a continuous annulus of cambial cells which then begin their division where one daugther cell is an initial to replace the mother cell and the other daughter cell differentiates into either secondary xylem or phloem. Usually the secondary xylem is produced in much greater amounts than the secondary phloem. The other secondary growth is the intiation of the cork cambium from the epidermal or cortical layers. Thus the epidermis is replaced with a tissue called the periderm which possesses several types of cells. The cork cambium or phellogen which divides regularly to produce the two other cell types: the phellem cells, which are heavily ...

Magnesium-28 was applied to specific leaves of bean (Phaseolus vulgaris) and barley (Hordeum vulgare) plants. After 24 hours, as much as 7% of the absorbed Mg was exported from the treated bean leaves and 11% was transported basipetally from the treated zone of the barley leaves. Transport of Mg did not occur past a heat-killed section of the treated leaf, thereby indicating that translocation took place via the phloem. Mg movement in the phloem was also evident in autoradiograms of bean stem segments in which the xylem was separated from the phloem by a thin sheet of plastic.. ...

LS along xylem vessels. The central vessel is a mature secondary vessel-element and shows typical bordered (elliptical-elongate) pits in the (dead) secondary cell-walls. These vessels are formed after cell-elongation has finished as their rigid structure would cause them to fracture if they were formed earlier, during primary growth. The vessel-walls formed during primary growth need to be able to accommodate cell elongation stages and so will have helical or circular (lignin) bands that fulfil this requirement - a readily observable character that allows identification of primary vs secondary xylem.... The vessel that has been torn by the microtome knife, to the left of the bordered pitted vessel, is such a vessel with helical lignification ...

Cell-to-cell communication is crucial for the development of multicellular organisms, especially during the generation of new tissues and organs. Secondary growth--the lateral expansion of plant growth axes--is a highly dynamic process that depends on the activity of the cambium. The cambium is a stem cell-like tissue whose activity is responsible for wood production and, thus, for the establishment of extended shoot and root systems. Attempts to study cambium regulation at the molecular level have been hampered by the limitations of performing genetic analyses in trees and by the difficulty of accessing this tissue in model systems such as Arabidopsis thaliana. Here, we describe the roles of two receptor-like kinases, REDUCED IN LATERAL GROWTH1 (RUL1) and MORE LATERAL GROWTH1 (MOL1), as opposing regulators of cambium activity. Their identification was facilitated by a novel in vitro system in which cambium formation is induced in isolated Arabidopsis stem fragments. By combining this system with laser

In dicot roots, the vascular structures are located in the middle of the root, surrounded by vascular cambium. Primary dicot stem - Characteristics features of primary dicot stems are- ... * In some places stomata is present and they have dumb bell shaped guard cells. Barley 2. 1. In dicots, the stems have vascular bundles, consisting of two structures, the xylem, and the phloem. Explanation: Fibrous root is also called the adventitious root which is the characteristic of monocotyledonous plants. It has epidermis, cortex, endodermis, pericycle, vascular bundles and pith. ... * Pericycle gives rise to lateral roots which is the part of â ¦ The meristem of primary tissue divides. Monocotyledons: The number of individual parts of the flowers is â ¦ As is typical with monocots, ...
Section through Rhynie chert, a siliceous rock found in Scotland, showing the stems of a fossil plant Rhynia major. Rhynia was a primitive vascular plant consisting of an underground rhizome which bore upright aerial stems. The stems contained tracheids (primitive xylem cells for water transportation) & epidermal cells with stomata. There were no leaves or scales although the stems did have spiny hairs scattered over the surface. The fertile branches bore cylindrical sporangia at their tips, which contained the spores. These fossil plants grew to 30-60 centimetres (1-2ft) & are found mainly among rocks of the Devonian period. - Stock Image E440/0016

Another advantage of using gene patterns for HR family classification is that they provide opportunity for generation of fuzzy classification rules which extend the scope of applicabilty of fuzzy-genetic classification approach. Moreover, as the fuzzy rule technique is broadly used in soft computing and artificial intelligence, the fuzzy classification rules offer possibilities for the methods of artificial intelligence to be used in other fields related to the irrigation practice. A Fuzzy Classification Rule (FCR) is usually of the form IF...THEN..., where both the IF and THEN parts are natural language expressions of some fuzzy classes or their combinations. Fuzzy Logic provides techniques for computing, with these classes aimed at specific problem-solving (classification, pattern recognition, prediction, etc.).. Each HR family is described by a specific FCR. Being different for each family, FCR provides an integral fuzzy description of this family and, therefore, can be used for the purpose ...

Tap water is often added with chemicals or is naturally harder (calcium oxide). If youre seeing raised, brownish lesions be sure to check the temperature around the plant. But has it really gone bad, or is it just a cosmetic defect? Lucky Bamboo sometimes suffers from mold that appears on its stems or leaves. What if you see some black spots on the stems or there is a certain, questionable smell to it? In cool, moist weather, small black spots appear on foliage, which starts to turn yellow and eventually drops off. https://www.thegardenprepper.com/black-spots-on-broccoli-stems-safe-to-eat - John Petrak Aug 20 16 at 7:33 If you want to be extra careful, be sure to isolate your plant for a few days from your other plants, inspecting its leaves and stems everyday. They I tried the soap water mix and about half of them (mainly the larger ones) fell off straight away. The main culprits are mites. Thus, it is best to store it in a different way, if you plan on eating the vegetable at a later time. ...
The concept of a factor of safety is used by biologists and engineers who generally agree that structures must be mechanically reliable, i.e. that structures must be capable of coping with unprecedented loads without failing. These factors can be calculated for individual structures or for a population of otherwise equivalent mechanical structures differing in their load capabilities. Objective methods for quantifying factors of safety for biological structures are nevertheless difficult to devise because (1) actual (working) loads are defined by environmental conditions that can vary widely, (2) breaking loads (capability) of otherwise mechanically equivalent structures can likewise vary as a result of developmental variation, and (3) specific criteria for failure must be determined a priori. In this paper, we illustrate and discuss two methods for computing factors of safety for plants. One method works well for individual stems or entire plants, the other is useful when dealing with a ...
I was trimming back these stems and noticed they were hollow -- I kept trimming back to the end of the dead steam that meets the live part of the plant. I noticed what looks like a small worm or larva in the stem ...
The pith of fibres is oblique while that of sclereids is straight. They are commonly found in the flesh of fruits such as Guava and endocarp region of apple. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. Ø They have thick secondary cell wall. However, they are further divided into five classes depending on the size and shape of the cell. The core difference between fibres and sclereids is the shape. Fibres are distributed throughout the plant as they primarily function to provide mechanical strength to the plant. Based on the main cell types in each tissue, we can distinguish two classes of plant shells: 1) single cell type and 2) multi-cell type structures.
