A cDNA clone corresponding to a gibberellin-responsive gene (CRG16) was isolated from cucumber hypocotyls. CRG16 was deduced to encode an extremely hydrophobic protein of 65 amino acids. The deduced sequence exhibited no significant homology to other proteins. Levels of CRG16 mRNA reflected the gibberellin-induced elongation of cucumber hypocotyls.
The involvement of lipase in flowering is seldom studied, and this research provides evidence that fatty acids produced by lipase affect flowering. OSAG78 encoding a patatin-like protein was isolated from Oncidium Gower Ramsey. OSAG78 fused with green fluorescent protein was found to localize at the cell membrane. Transgenic Arabidopsis overexpressing OSAG78 demonstrated higher lipase activity ...
مقدمه : سقط شایع ترین عارضه بارداری بوده و در ? 15 حاملگی ها رخ می دهد . اختلالات ایمنولوژیک یکی از علل شایع سقط می باشد که خود شامل فاکتورهای آلوایمیون و اتوایمیون می باشد . با توجه به نقش آنتی بادی ها ضد تیروئیدی از جمله anti-tpo به عنوان یک فاکتور اتوایمیون در ایجاد سقط های خودبه خودی ومکرر ، در این مطالعه به بررسی ارتباط بین این دو می پردازیم . اهداف : هدف کلی : بررسی ارتباط بین سطح anti-...
An inhibitor extracted from short day treated Acer negundo leaves was compared to abscisic acid in 4 different solvent systems. The chromatographic properties of abscisic acid and the inhibitor were in very close agreement. Treatment of Acer negundo plants under non-hardening preconditions (long days) with either the inhibitor or abscisic acid increased hardiness after a hardening period of 3 w...
A plant's eventual size depends on the integration of its genetic program with environmental cues, which vary on a daily basis. Both efficient carbon metabolism and the plant hormone gibberellin are required to guarantee optimal plant growth. Yet, little is known about the interplay between carbon metabolism and gibberellins that modulates plant growth. Here, we show that sugar starvation in Ar...
Floral buds were induced either by 8 h photoperiods or by the application of GA3 and GA13 in Impatiens bahamina. Total enzyme activity was not directly related to floral morphogenesis although some interesting qualitative correlations existed. Thus, the presence of a new isoenzyme of amylase {Rp 0-05) may be related to flower formation since it was present only in the induced plants and not in ...
Influence of jasmonic acid on endogenous gibberellin and abscisic acid in salt-stressed chard plant.
The endogenous gibberellin (GA) and abscisic acid (ABA) contents as an effect of different application times of jasmonic acid (JA) in chard seedlings exposed to salt stress were investigated. Endogenous ABA content was increased by JA treatment after NaCl treatment, rather than after JA application before NaCl treatment. JA application after NaCl treatment caused higher ABA content than treatme...
