Transcriptomic analysis of grape (Vitis vinifera L.) leaves during and after recovery from heat stress.

ABSTRACT:

Background

Grapes are a major fruit crop around the world. Heat stress can significantly reduce grape yield and quality. Changes at the molecular level in response to heat stress and subsequent recovery are poorly understood. To elucidate the effect of heat stress and subsequent recovery on expression of genes by grape leaves representing the classic heat stress response and thermotolerance mechanisms, transcript abundance of grape (Vitis vinifera L.) leaves was quantified using the Affymetrix Grape Genome oligonucleotide microarray (15,700 transcripts), followed by quantitative Real-Time PCR validation for some transcript profiles.

Results

We found that about 8% of the total probe sets were responsive to heat stress and/or to subsequent recovery in grape leaves. The heat st
