Nitrous oxide (N2O) emissions from N fertilizer applied to row crops makes up a large portion of the greenhouse gas loading atmosphere. Guayule (Parthenium argentatum A. Gray) is desert perennial shrub being promoted for Central Arizona farmers as source natural rubber and hypoallergenic latex. Emissions N2O crop uptake have not been previously quantified in this multi-year cropping system. A 2...
Although the Compositae harbours only two major food crops, sunflower and lettuce, many other species in this family are utilized by humans and have experienced various levels of domestication. Here, we have used next-generation sequencing technology to develop 15 reference transcriptome assemblies for Compositae crops or their wild relatives. These data allow us to gain insight into the evolut...
Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...
با توجه به اهمیت گیاهان مولد کائوچو در دنیا، طرح بررسی سازگاری کولتیوارهای مختلف گیاه وایول در ایران تدوین و تحقیق در مورد بهترین روشهای جوانه زنی بذر، زمان و شرایط مناسب کشت آن انجام گرفت و بعد در پی بررسیهای انجام شده، پایه های حاصل از کشت بذر 5 کولتیوار وایول در سال 1375 به بستر زمین انتقال و در قالب طرح بلوکهای کامل تصادفی در چهار تکرار، مطالعات سازگاری در مورد آنها انجام گرفت. بررسی میانگی...
Cytochrome P450s exist ubiquitously in all organisms and are involved in many biological processes. Allene oxide synthase (AOS) is a P450 enzyme that plays a key role in the biosynthesis of oxylipin jasmonates, which are involved in signal and defense reactions in higher plants. The crystal structures of guayule (Parthenium argentatum) AOS (CYP74A2) and its complex with the substrate analog 13(...
