trichosanthes kirilowii, an important economic plant in china, is sensitive to chilling. to investigate the effect of abscisic acid (aba) treatment on the chilling tolerance of trichosanthes kirilowii maxim, different concentrations of aba were sprayed on trichosanthes kirilowii leaves and the resulting catalase (cat) and superoxide dismutase (sod) activities and the malondialdehyde (mda) conte...

to better understand seed dormancy breaking of bread wheat (triticum aestivum l.rl4137), we examined protein synthesis in dormant and after-ripened seeds.we used six treatments including dormant seed, dormant seed that were subjected to gibberllic acid (ga3) for 10 hours, dormant seed with one, three and six weeks of after-ripening and finally six weeks after-ripened seed subjected to abscisc a...

BACKGROUND Retention rate, efficacy, and safety of abatacept (ABA) was compared between patients with rheumatoid arthritis receiving ABA as monotherapy to those in combination ABA + conventional synthetic DMARD (csDMARD). METHODS The patients were obtained from the ORA registry. The retention rate was analysed in two ways: (1) therapeutic strategy retention, in which the addition of a csDMARD...

Drought stress at the reproductive stage causes pollen sterility and grain loss in wheat (Triticum aestivum). Drought stress induces abscisic acid (ABA) biosynthesis genes in anthers and ABA accumulation in spikes of drought-sensitive wheat varieties. In contrast, drought-tolerant wheat accumulates lower ABA levels, which correlates with lower ABA biosynthesis and higher ABA catabolic gene expr...

Biochemical, genetic and imaging studies support the involvement of the serotonin (5-HT) system in anorexia nervosa. Activity-based anorexia (ABA) is considered an animal model of anorexia nervosa, and combines scheduled feeding with voluntary running wheel activity (RWA). We investigated the effect of d-fenfluramine (d-FEN) treatment on development and propagation of ABA. d-FEN is an appetite ...

Expression of the Em gene was characterized in rice (Oryza sativa L.) suspension cultures following exposure of the cultures to various combinations of abscisic acid (ABA) and salt. Response-saturating concentrations of either ABA (50 micromolar) or NaCl (0.4 molar) rapidly induced (by 60 minutes) the accumulation of Em mRNA, with a maximum accumulation occurring 12 to 24 hours after treatment....

The length of potato tuber dormancy depends on both the genotype and the environmental conditions during growth and storage. Abscisic acid (ABA) has been shown to play a critical role in tuber dormancy control but the mechanisms regulating ABA content during dormancy, as well as the sites of ABA synthesis, and catabolism are unknown. Recently, a temporal correlation between changes in ABA conte...

Excessive physical activity is commonly described as symptom of Anorexia Nervosa (AN). Activity-based anorexia (ABA) is considered an animal model for AN. The ABA model mimics severe body weight loss and increased physical activity. Suppression of hyperactivity by olanzapine in anorectic patients as well as in ABA rats suggested a role of dopamine and/or serotonin in this trait. Here, we invest...

The effect of fluridone on the growth of plants and drought stressinduced abscisic acid (ABA) accumulation were studied in mature leaf tissue of Vicia faba L. plants grown under different light intensity. Drought stress was induced by allowing the leaves to lose 12% of fresh weight. Treatment of Vicia plants (grown at high light intensity – 600μmol.m-2.s-1) with 10μmoles fluridone caused a cons...
