متن کاملContent during Abscisic Acid Induced Freezing Tolerance in Bromegrass Cells1
Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...
متن کاملEvaluation of Biochemical and Physiological Responses of Seven Olive Cultivars in Relation to Freezing Tolerance
Abstract: Temperature is one of the most important factors limiting the production and distribution of olive. Different olive cultivars show diverse responses to low temperature and so, the selection of cold tolerant cultivars is the most effective method to avoid frost damages. The main purpose of this study was to compare freezing tolerance of seven olive cultivars and to investigate the rel...
متن کاملCold-regulated gene expression and freezing tolerance in an Arabidopsis thaliana mutant.
Low temperature is an important environmental factor influencing plant growth and development. In this study, we report the characterization of a genetic locus, HOS2, which is defined by three Arabidopsis thaliana mutants. The hos2-1, hos2-2 and hos2-3 mutations result in enhanced expression of RD29A and other stress genes under low temperature treatment. Gene expression in response to osmotic ...
متن کاملGene expression in response to abscisic acid and osmotic stress.
Abscisic acid (ABA) was discovered in the 1950s to be a phytohormone affecting leaf abscision and bud dormancy. It was soon characterized as a sesquiterpene derived from mevalonate although certain steps of its biosynthesis in plants are still unknown (Li and Walton, 1987; Zeevaart and Creelman, 1988). Continuing work on ABA has shown that it mediates various developmental and physiological pro...
