A comprehensive analysis of the combined effects of high light and high temperature stresses on gene expression in sunflower.

ABSTRACT:

Background and aims

Although high light (HL) and high temperature (HT) stresses have been extensively investigated, a global analysis of their combined effects on the transcriptome of any plant species has not yet been described. Sunflower is an agronomically important oil crop frequently subjected to these stress factors. Because results in model plants may not always translate well to crop plants, responses of sunflower (Helianthus annuus) to HL, HT and a combination of both stresses were analysed by profiling gene expression in leaves and immature seeds.

Methods

Plants were grown in HL (600 microE m(-2) s(-1)), HT (35 degrees C) and a combination of HL and HT (HL + HT), and gene expression in leaves and immature seeds was profiled using cDNA microarrays containing more th
