Comprehensive expression profile analysis of the Arabidopsis Hsp70 gene family.
We isolated cDNA clones for two nuclear-encoded, organellar members of the Arabidopsis hsp70 gene family, mtHsc70-2 (AF217458) and cpHsc70-2 (AF217459). Together with the completion of the genome… Expand

Exposure of Arabidopsis to low temperatures results in cold acclimation where freezing tolerance is enhanced. To achieve a wider view of the role of transcriptome to biochemical changes that occur… Expand
β-Amylase Induction and the Protective Role of Maltose during Temperature Shock1
A number of studies have demonstrated β-amylase induction in response to abiotic stress. In the present work, a temperature response profile in 5°C increments from 45°C to 0°C showed that induction… Expand
Extension of the linkage map in Citrus using random amplified polymorphic DNA (RAPD) markers and RFLP mapping of cold-acclimation-responsive loci
Genetic mapping with RAPD markers has been initiated in Citrus. Reproducible polymorphism of amplified DNA fragments was obtained with approximately half of the 140 random primers tested, revealing… Expand

Plants possess inducible tolerance mechanisms that extend the temperature range for survival during acute temperature stress. The inducible mechanisms of cold acclimation and acquired thermotolerance… Expand
Glucan, Water Dikinase Activity Stimulates Breakdown of Starch Granules by Plastidial β-Amylases1[W][OA]
Glucan phosphorylating enzymes are required for normal mobilization of starch in leaves of Arabidopsis (Arabidopsis thaliana) and potato (Solanum tuberosum), but mechanisms underlying this dependency… Expand
RNA interference of Arabidopsis beta-amylase8 prevents maltose accumulation upon cold shock and increases sensitivity of PSII photochemical efficiency to freezing stress.
It has been suggested that beta-amylase (BMY) induction during temperature stress in Arabidopsis could lead to starch-dependent maltose accumulation, and that maltose may contribute to protection of… Expand
Acquired tolerance to temperature extremes.
Acquired tolerance to temperature stresses is a major protective mechanism. Recent advances have revealed key components of stress signal transduction pathways that trigger enhanced tolerance, and… Expand
