Interplay between cold-responsive gene regulation, metabolism and RNA processing during plant cold acclimation.
Temperate plants are capable of developing freezing tolerance when they are exposed to low nonfreezing temperatures. Acquired freezing tolerance involves extensive reprogramming of gene expression and metabolism. Recent full-genome transcript profiling studies, in combination with mutational and transgenic plant analyses, have provided a snapshot of the complex transcriptional network that oper...
متن کاملLow temperature signal transduction during cold acclimation: protein phosphatase 2A as an early target for cold-inactivation
The authors have previously shown that cold acclimation and cold acclimation-specific (cas) gene expression in alfalfa require cold-triggered calcium influx and phosphorylation of specific pre-existing proteins. In this study, the authors used the expression of cas15 gene as an end-point marker to examine the role of protein phosphorylation in low temperature signal transduction in alfalfa cell...
متن کاملGene regulation during cold acclimation in plants
doi: 10.1111/j.1399-3054.2005.00596.x Cold acclimation involves precise signaling and regulation of the transcriptome. The plasma membrane may be the primary cold-stress sensor, and FRY1/HOS2 inositol polyphosphate 1-phosphatase regulates cytosolic inositol-1,4,5-triphosphate levels, which in turn control cytosolic Ca2þ signatures and cold acclimation. Cold-induced reactive oxygen species may a...
متن کاملLowTemperature Signal Transduction: lnduction of Cold Acclimation-Specific Genes of Alfalfa by Calcium at 25OC
To study the role of calcium in cold acclimation, we examined the relationship between calcium influx and accumulation of transcripts of two cas (cold acclimation-specific) genes of alfalfa, cas75 and cas78. Whereas a decline in temperature from 25 to 15OC had little effect on the influx of extracellúlar 45Ca2+, an increasing influx was observed when the temperature was lowered further. The inf...
