The hemolymph of Sarcophaga peregrina (flesh fly) larvae was found to contain multiple inhibitors of hemocyte cysteine protease. One of them, named sarcocystatin A, was purified and found to be a mixture of the components sarcocystatin A, and AP in a molar ratio of 2:l. These components can exist in either the associated or dissociated form. The apparent heterogeneity of the protease inhibitors...
Poly A(+) mRNA was isolated from Vicia faba leaves and translated in vitro using a rabbit reticulocyte translation system. From analysis of the total translation products, the major proteins synthesized in vitro were 32 kilodaltons and 20 kilodaltons. When antibodies to Vicia faba polyphenoloxidase were added, a specific immunoprecipitable protein was observed. This protein's molecular weight w...
REVIOUS experiments have shown that quantitatively the response P of chromosomes of Vicia faba in pachytene to X-rays is approximately the same as that of the same species at the onset of the somatic prophase (MARSHAK 1939a). CREIGHTON (1941) using methods similar to those employed in the Vicia studies found that meiotic chromosomes are only a sixth as sensitive as the mitotic chromosomes in Ch...
FIA functions as an early signal component of abscisic acid signal cascade in Vicia faba guard cells
An abscisic acid (ABA)-insensitive Vicia faba mutant, fia (fava bean impaired in ABA-induced stomatal closure) had previously been isolated. In this study, it was investigated how FIA functions in ABA signalling in guard cells of Vicia faba. Unlike ABA, methyl jasmonate (MeJA), H(2)O(2), and nitric oxide (NO) induced stomatal closure in the fia mutant. ABA did not induce production of either re...
Cadmium (Cd) is one of the most toxic heavy metals in plants. To investigate whether Cd induces common plant defense pathways, different physiological and molecular reactions, including modifications in glutathione (GSH) level, activity and gene expression of glutathione reductase (GR) enzyme were characterized in roots of hydroponically cultivated-Vicia seedlings during 12, 24 and 48 h. Vicia ...
مطالعات سیتوژنتیک بر روی 6 تاکسون متعلق به بخش vicia از جنس vicia نشان داد که کلیه تاکسون ها دیپلوئید است و عدد کروموزومی چهار تاکسون v. sativa var. amphicarpa، v. grandiflora، v. lathyroides و v. sativa var. cordata برای اولین بار از ایران گزارش شد. فرمول کاریوتیپی در تاکسون های مورد مطالعه متفاوت بود؛ به طوری که فرمول کاریوتیپی و عدد کروموزومی درتاکسون های v. sativa var. sativa (st4+m2)، v. l...
برای بررسی سیتوتاکسونومی جنس vicia در ایران، از 40 تاکسون مختلف از 13 بخش جهت مطالعه کروموزوم ها در مرحله متافاز میتوز استفاده شد. کمترین عدد دیپلوئید مشاهده شده برابر با 10 و بیشترین برابر با 28 بود. در میان اعداد دیپلوئید شمارش شده 3 عدد پایه کروموزومی در تاکسون های جنس vicia در ایران (x=5, 6, 7) مشاهده شد. بر این پایه، این جنس دارای دو سطح دیپلوئیدی و تتراپلوئیدی در ایران است. در تاکسون های ...
