Transcription profiling of barley roots and shoots from the cultivars Maythorpe and Golden Promise grown under normal and high salinity conditions

ABSTRACT: Salt Stress response of salt-tolerant genotype Golden Promise compared to Maythorpe; Barley1 GeneChip was used to find differential expression between two barley genotypes under control and salt stress conditions at vegetative stage of growth Experiment Overall Design: Roots (tips) and shoot (crown and growing point) tissue was used for hybridization to GeneChips

BACKGROUND: Golden Promise is a salt-tolerant spring barley closely related to Maythorpe. Salt tolerance in Golden Promise has been attributed to a single mutation at the Ari-e locus (on 5H) resulting from irradiation of Maythorpe. Golden Promise accumulates lower shoot Na+ compared to Maythorpe when growing under saline conditions. This study focused on elucidating the genetic basis and mechanisms involved in this difference. RESULTS: The level of polymorphism between the two genotypes was expl  ...[more]
