The aim of this study investigate the toxicity effect of (GA3) on liver & kideny function, activity of acetylcholine and antioxidant at different doses as well as the possibility of recovery after apostasy GA3 Twenty five adult male albino Rats were .equally divided into five groups. Group 1 served as control. Groups 2&3 received GA3 daily in drinking water in two gradually increasing doses of ...

field trials with ficus benjamina l.were conducted at the experimental farm of faculty of agriculture, university azad jiroft in 2012 growth seasons. the aim of this work is to study the effect of foliar application with gibberellic acid (ga3) and benzyladenine (ba) at 0, 100 and 200 mg.l-1 on the vegetative growth and photosynthetic pigments of ficus benjamina plants. the obtained results show...

The content of gibberellic acid (GA3) in male sex organs of Chara tomentosa L. was estimated using capillary electrophoresis. Young antheridia contained 0.25 microg GA3 while mature ones 0.48 microg per antheridium. Although there are significant differences in GA3 content in antheridia between C. vulgaris and C. tomentosa, these values calculated per one spermatid are 2.4 and 3.3 pg, respectiv...

The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilli...

Bioactive gibberellins (GAs) play a key regulatory role in plant growth and development. In the biosynthesis of GAs, GA3-oxidase catalyzes the final step to produce bioactive GAs. Thus, the evaluation of GA3-oxidase activity is critical for elucidating the regulation mechanism of plant growth controlled by GAs. However, assessing catalytic activity of endogenous GA3-oxidase remains challenging....

In this research, our aim was to determine the effects of gibberellic acid, which was applied to safflower plants (Carthamus tinctorius L. cv. Dinçer 5-118) for pollen sterility induction, on some physiological activity and endogenous hormone levels of the seeds. Exogenously applied gibberellic acid (GA3) strongly influenced the endogenous hormone levels of the seeds by decreasing the levels of...

Valeriana officinalis is an important medicinal herb commonly found in Kashmir valley. This study forms an important preliminary step for in-vitro micro propagation of V. officinalis from breaking the seed dormancy, inducing rapid seed germination and its subsequent micro propagation. We investigated the influence of pretreatment of V. officinalis seeds with reduced temperature and light on see...

A murine monoclonal antibody (GA3) obtained by immunizing mice with cells of the human erythroleukemic cell line K562 is shown to define a 105 kilodalton (kd) membrane antigen on K562 cells that is restricted within the hematopoietic system to the erythroid lineage and to a minor population of CD3, CD4 positive T lymphocytes. Cocapping studies and immunoprecipitation experiments performed with ...

The effects of the plant growth promoter gibberellic acid (GA3) and plant growth retardant chlormequat chloride (CCC) on biomass and quality of Angelica dahurica var. formosana plants were investigated employing physiological and biochemical methods. Plants were sprayed with GA3 or CCC at rosette stage and coumarin content was analyzed by high performance liquid chromatography (HPLC) after harv...

Type VI secretion systems (T6SSs) are multiprotein complexes best studied in Gram-negative pathogens where they have been shown to inhibit or kill prokaryotic or eukaryotic cells and are often important for virulence. We recently showed that T6SS loci are also widespread in symbiotic human gut bacteria of the order Bacteroidales, and that these T6SS loci segregate into three distinct genetic ar...
