A simple HPLC-fluorescence detection of nitric oxide in cultivated plant cells by in situ derivatization with 2,3-diaminonaphthalene. (1/32)

An HPLC method with fluorescence detection for the determination of nitric oxide (NO) in cultivated plant cells (Agave pacifica, Agavaceae) was developed. NO was derivatized in situ with 2,3-diaminonaphthalene (DAN) as a labeling reagent and converted to 1(H)-naphthotriazole. The maximum peak height of the derivative was observed by incubation for 3 h at 25 degrees C with 0.2 mM DAN. Excess reagent in cells was removed by washing 3 times with 5 ml of water. The calibration curve for authentic standard of DAN-NO spiked to cultivated plant cells showed a good linearity (r = 0.995) in the range of 5.0 to 50 pmol/g cell. The detection limit at a signal-to-noise ratio of 3 was 3.4 pmol/g cells. The proposed method was successfully applied to the monitoring of NO concentration with cell growth. The effect of thermal treatment on the concentration of NO in plant cells was also examined. The concentration of NO in cells treated at 5 degrees C for 1 h was significantly higher than that treated at 25 degrees C and 35 degrees C for 1 h (n = 3, p < 0.05).  (+info)

Aberrant meiotic behavior in Agave tequilana Weber var. azul. (2/32)

BACKGROUND: Agave tequilana Weber var. azul, is the only one variety permitted by federal law in Mexico to be used for tequila production which is the most popular contemporary alcoholic beverage made from agave and recognized worldwide. Despite the economic, genetic, and ornamental value of the plant, it has not been subjected to detailed cytogenetic research, which could lead to a better understanding of its reproduction for future genetic improvement. The objective of this work was to study the meiotic behavior in pollen mother cells and its implications on the pollen viability in Agave tequilana Weber var. azul. RESULTS: The analysis of Pollen Mother Cells in anaphase I (A-I) showed 82.56% of cells with a normal anaphase and, 17.44% with an irregular anaphase. In which 5.28% corresponded to cells with side arm bridges (SAB); 3.68% cells with one bridge and one fragment; 2.58% of irregular anaphase showed cells with one or two lagging chromosomes and 2.95% showed one acentric fragment; cells with two bridges and cells with two bridges and one acentric fragment were observed in frequencies of 1.60% and 1.35% respectively. In anaphase II some cells showed bridges and fragments too. Aberrant A-I cells had many shrunken or empty pollen grains (42.00%) and 58.00 % viable pollen. CONCLUSION: The observed meiotic irregularities suggest that structural chromosome aberrations have occurred, such as heterozygous inversions, sister chromatid exchanges, deletions and duplications which in turn are reflected in a low pollen viability.  (+info)

Initial net CO2 uptake responses and root growth for a CAM community placed in a closed environment. (3/32)

To help understand carbon balance between shoots and developing roots, 41 bare-root crassulacean acid metabolism (CAM) plants native to the Sonoran Desert were studied in a glass-panelled sealable room at day/night air temperatures of 25/15 degrees C. Net CO(2) uptake by the community of Agave schottii, Carnegia gigantea, Cylindropuntia versicolor, Ferocactus wislizenii and Opuntia engelmannii occurred 3 weeks after watering. At 4 weeks, the net CO(2) uptake rate measured for south-east-facing younger parts of the shoots averaged 1.94 micro mol m(-2) s(-1) at night, considerably higher than the community-level nocturnal net CO(2) uptake averaged over the total shoot surface, primarily reflecting the influences of surface orientation on radiation interception (predicted net CO(2) uptake is twice as high for south-east-facing surfaces compared with all compass directions). Estimated growth plus maintenance respiration of the roots averaged 0.10 micro mol m(-2) s(-1) over the 13-week period, when the community had a net carbon gain from the atmosphere of 4 mol C while the structural C incorporated into the roots was 23 mol. Thus, these five CAM species diverted all net C uptake over the 13-week period plus some existing shoot C to newly developing roots. Only after sufficient roots develop to support shoot water and nutrient requirements will the plant community have net above-ground biomass gains.  (+info)

Genetic differentiation in the Agave deserti (Agavaceae) complex of the Sonoran desert. (4/32)

The Agave deserti complex, comprising A. deserti, A. cerulata and A. subsimplex, represents a group of species and subspecies with a near allopatric distribution and clear differences in morphology. Genetic differentiation and taxonomic status with respect to spatial distribution of 14 populations of the complex were analyzed in an effort to understand the evolution and speciation process within the genus. Allelic frequencies, levels of genetic variation, expected heterozygosity (H(S)), proportion of polymorphic loci (P), and genetic differentiation (theta and Nei's genetic distance) were estimated using 41 putative RAPD loci. All three species show high levels of genetic variation (H(S)=0.12-0.29, P=63.4-95.1), and low genetic differentiation between populations and species (theta populations=0.14+/-0.02 (SE); G(st)=0.11+/-0.02). Accordingly, gene flow among populations was estimated as high by three different methods (N(m)=2.91-6.14). Nei's genetic distances between the three species were low compared to the values obtained from other Agavaceae, and there was no clear correlation with taxonomic divisions. In a UPGMA analysis, A. subsimplex and A. cerulata formed exclusive monospecific clusters, whereas the A. deserti populations appear in more than one cluster together with other species. The results were consistent with a pattern of genetic isolation by distance.  (+info)

Four new steroid constituents from the waste residue of fibre separation from Agave americana leaves. (5/32)

Three new steroidal saponins, named agamenosides H-J (1-3), and a new cholestane steroid agavegenin D (4) were isolated from the waste residue of fibre separation from Agave americana leaves, together with six known steroids. Structures of the new compounds 1-4 were deduced to be (22S,23S,24R,25S)-24-[(beta-D-glucopyranosyl)oxy]-5alpha-spirostane-3beta,6alpha, 23-triol 6-O-beta-D-glucopyranoside (1), (22S,23S,24R,25S)-5alpha-spirostane-3beta,23,24-triol 24-O-beta-D-glucopyranoside (2), (22S,23S,25R,26S)-23,26-epoxy-5alpha-furostane-3beta,22,26-triol 26-O-beta-D-glucopyranoside (3), and (22S,25S)-5alpha-cholestane-3beta,16beta,22,26-tetrol (4), respectively, by means of spectroscopic analysis, including extensive 1D and 2D NMR data, and the results of hydrolytic cleavage.  (+info)

Timing and rate of speciation in Agave (Agavaceae). (6/32)

The Agave (Agavaceae) are keystone species of semiarid to arid regions where the geographic center of origin is Mexico but whose populations spread from the southwestern U.S. through Central America, the Caribbean, and into northern South America. Our analyses indicate that Agave is a young genus, between 7.8 and 10.1 million years old, and yet it harbors the most species of any genera in the family. Of the eight genera in the family, Agave is paraphyletic with respect to three of them, and these four genera are often grouped into a genus termed Agave sensu lato, which harbors 208 of the 293 recognized species in the Agavaceae. In this article, we examine the phylogenetic limits of Agave sensu lato and present analyses elucidating the origin and rate of speciation in the group. These analyses lead to some new insights into the phylogenetic limits of Agave, indicate an estimated age of the family between 20 and 26 million years and an age of the Agave sensu lato of +info)

Isolation, characterization, and localization of AgaSGNH cDNA: a new SGNH-motif plant hydrolase specific to Agave americana L. leaf epidermis. (8/32)

GDSL and SGNH hydrolases are lipases involved in a wide range of functions, behaving in many cases as bifunctional enzymes. In this work, the isolation and characterization of AgaSGNH, a cDNA encoding a member of the SGNH-hydrolase superfamily from young leaf epidermis of the monocot Agave americana L., is reported. The protein possesses a typical signal peptide at its N-terminus that allows its secretion to the epidermis cell wall, as verified by immunolocalization experiments. In addition, the AgaSGNH sequence contains a His-Leu-Gly-Ala-Glu (HLGAE) motif which is similar to that observed in other plant acyltransferases. Expression levels by northern blot and in situ localization of the corresponding mRNA, as well as the immunolocalization of the protein in Agave young leaves indicate that the protein is specifically present in the epidermal cells. The detailed study performed in different parts of the Agave leaf confirms two aspects: first, the expression of AgaSGNH is limited to the epidermis, and second, the maximum mRNA levels are found in the epidermis of the youngest zones of the leaf which are especially active in cutin biosynthesis. These levels dramatically decrease in the oldest zone of the leaf, where the presence of AgaSGNH mRNA is undetectable, and the biosynthesis of different cuticle components is severely reduced. These data could be compatible with the hypothesis that AgaSGNH could carry out both the hydrolysis and the transfer, from an activated acyl-CoA to a crescent cutin in Agave americana leaves and, therefore, be involved in the still unknown mechanism of plant cutin biosynthesis.  (+info)

  • and lucky for them, they found a plant (agave) whose juices they could readily distill. (
  • Agave is a perennial, flowering plant, primarily found in Mexico, but some species grow in the southwestern US and parts of South America, and even as far north as Alberta, Canada. (
  • The word piña is used to describe the heart of the agave plant, refers to the idea that the heart resembles a pinecone or pineapple. (
  • Each plant can be used only once, which means agave, unlike grapes and many other crops, needs to be planted anew every year. (

  • The agave plant produces large amounts of sugar that is easily fermented to bioethanol, and suitable also for use as raw material for products such as paints, plastics and high value chemicals which normally use fossil fuels. (
  • This plant is very different from all other types of agave. (
  • It can take nearly a decade for one agave plant to reach maturity and be ready for harvesting. (
  • The plant was used by the Spaniards to create the first agave distillate after conquering Mexico in the 16th century. (
  • The small town of Tequila was where the blue agave plant naturally grew, so it became famous for producing the most delicious form of the drink. (
  • The cool and dry climate allows the plant to mature more slowly - so the piña (the heart of the Agave) grows larger and sweeter. (
  • It takes a bit longer to remove this part of the agave plant, but the effort is absolutely worth it. (
  • Tequila is an objectively strong drink (it usually contains about 38% alcohol) made from blue agave, a plant native to the sandy soils of Mexico. (
  • Tequila is distillation drinks that made of agave plant. (

  • The agave-based straws feature a mouthfeel and texture similar to traditional plastic straws, with the agave fibers visibly creating a natural, organic tan color. (
  • Jose Cuervo has actively been involved in 21 years of community projects through its foundation, from education to healthcare, providing local businesses in Tequila, Mexico with agave fibers for paper and beauty products and supplying agave fibers to American car manufacturers for research into sustainable, agave-based car parts. (
  • The next step in the process is to bake the agave piñas in an oven to break down the sugars and fibers in the agave. (
  • The shredder takes the large chunks of agave and turns them into fine fibers, all without damaging them. (
  • The more fine the agave fibers are, the more complex the tequila is. (

(
  • In 2020, millions of Jose Cuervo biodegradable agave-based straws will be rolled out at bars, restaurants, and Jose Cuervo events across the US and Mexico in a bid to reduce the consumption of regular plastics from the tequila-drinking experience. (
  • The debut of our biodegradable, agave-based drinking straws is a new step in utilizing the full potential of this very special Mexican agricultural product. (
  • The agave fiber in our bio-based composites is an ideal material that not only works as a replacement to plastic, but simultaneously reduces the dependency on petroleum-based polymers, fossil fuels and water for the production of our straws. (
  • The juice is then extracted from the core of the agave, called the piña . (
  • An alternative method used to process the agave juice without heat is described in a United States patent for a process that uses enzymes derived from the mold Aspergillus niger to convert the inulin-rich extract into fructose. (
  • The researchers modelled ethanol yields from analysis of whole plants, waste leaves from existing agave industries and agave juice. (
