Transcription profiling by array of Cabernet Sauvignon grapes after growth in increased salinity or water deprivation


ABSTRACT: Potted Cabernet Sauvignon vines in the greenhouse were exposed to irrigated controls, non-irrigated water-deficits, and saline treatments for 16 days. Plant shoot tips were harvested every 4 days (0,4,8,12, and 16 days) to measure the progression of changes of global gene expression due to the stress. PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Grant Cramer. The equivalent experiment is VV2 at PLEXdb. time: Day 0 - stress: Control(3-replications); time: Day 4 - stress: Control(3-replications); time: Day 4 - stress: Water-Deficit(3-replications); time: Day 4 - stress: Salinity(3-replications); time: Day 8 - stress: Control(3-replications); time: Day 8 - stress: Water-Deficit(3-replications); time: Day 8 - stress: Salinity(3-replications); time: Day 12 - stress: Control(3-replications); time: Day 12 - stress: Water-Deficit(3-replications); time: Day 12 - stress: Salinity(3-replications); time: Day 16 - stress: Control(3-replications); time: Day 16 - stress: Water-Deficit(3-replications); time: Day 16 - stress: Salinity(3-replications)

Grapes are grown in semiarid environments, where drought and salinity are common problems. Microarray transcript profiling, quantitative reverse transcription-PCR, and metabolite profiling were used to define genes and metabolic pathways in Vitis vinifera cv. Cabernet Sauvignon with shared and divergent responses to a gradually applied and long-term (16 days) water-deficit stress and equivalent salinity stress. In this first-of-a-kind study, distinct differences between water deficit and salinit  ...[more]
