Plants are the only living organisms which have to suffer a lot from automobile exhaust pollution because they remain static at their habitat. But such roadside plants like Nerium indicum Mill., Boerhaavia diffusa L., Amaranthus spinosus L., Cephalandra indica Naud., and Tabemaemontana divaricata L. can easily avoid the effects of air pollution by altering their physiological pathways pertainin...
The swamp eel, Monopterus albus, is an obligatory air-breathing teleost which can undergo long period of emersion, has high environmental and tissue ammonia tolerance, and can survive in brackish water. We obtained a cDNA sequence of glutamate dehydrogenase (gdh), which consisted of a 133-bp 5' UTR, a complete coding sequence region spanning 1629 bp and a 3' UTR of approximately 717 bp, from th...
In order to determine their taxonomic significance, 10 pericarp structure characters were scored for 21 Amaranthus L. taxa. In many, peri carp patterns permit recognition of the taxa as species. Differences between cultivated taxa and their wild relatives offer new arguments against their taxonomic union. The relationships between other closely related taxa are also analyzed (A. quitensis and A...
با توجه به اهمیت شناسایی دقیق آفات کلیدی و گیاهان میزبان آن ها در یک منطقه به منظور کنترل موفقیت آمیز آفات، فون ساقه خوارهای جنس chilo zincken, 1817 (lepidoptera: pyralidae) و گیاهان میزبان آنها در مازندران مورد بررسی قرار گرفت. چهار گونه ساقه خوار شامل c. partellus swinhoe، c. phragmitellus hubner، c. suppressalis walker و c. sacchariphagus indicus (kapur) جمع آوری شدند که گونه اخیر برای فون ...
گونه petasites albus (l.) gaertner به عنوان گزارش جدیدی از جنگلهای شمال ایران نام برده می شود. این گونه از petasites hybridus (l.) p. gaertner به علت داشتن کرک های دائمی تار عنکبوتی در زیر برگها و گل آذینی بلند و کشیده و گل های سفید رنگ با برگه های گریبانه ای غده دار متفاوت است.
In recent years, nutraceuticals attracted a great amount of attention in the biomedical research due to their significant contribution as natural agents for prevention of various health issues. Ethanolic extracts from the ungerminated and germinated seeds of Lupinus albus L. and Lupinus angustifolius L. were analyzed for the content in isoflavones (genistein) and cinnamic acid derivatives. Addi...
Genetic variability, heritability and genetic advance studies in Amaranthus (Amaranthus tricolor L.)
A previously unknown glyphosate resistance mechanism, amplification of the 5-enolpyruvyl shikimate-3-phosphate synthase gene, was recently reported in Amaranthus palmeri. This evolved mechanism could introgress to other weedy Amaranthus species through interspecific hybridization, representing an avenue for acquisition of a novel adaptive trait. The objective of this study was to evaluate the p...
