Transcriptional profiles of primary metabolism and signal transduction-related genes in response to water stress in field-grown sunflower genotypes using a thematic cDNA microarray.

Abstract excerpt

A sunflower cDNA microarray containing about 800 clones covering major metabolic and signal transduction pathways was used to study gene expression profiles in leaves and embryos of drought-tolerant and -sensitive genotypes subjected to water-deficit stress under field conditions. Using two-step ANOVA normalization and analysis models, we identified 409 differentially expressed genes among genotypes, water...
