Transcription profiling of SALK_084897 or SAIL_303_D08 Arabidopsis plants grown under normal conditions or with moderate light and drough treatment applied


ABSTRACT: 4 week old Arabidopsis plants, of ecotype Columbia, SALK_084897 or SAIL_303_D08 were either grown under normal conditions or grown under normal conditions for before having a moderate light and drought treatment applied. Light and drought treatment was applied by withholding water for 5 days prior to transfer to 300 uE m-2 s-1 light conditions. Samples were collected after 3 days of treatment or for the same age plants grown under normal conditions.

Treatment of Arabidopsis (Arabidopsis thaliana) alternative oxidase1a (aox1a) mutant plants with moderate light under drought conditions resulted in a phenotypic difference compared with ecotype Columbia (Col-0), as evidenced by a 10-fold increase in the accumulation of anthocyanins in leaves, alterations in photosynthetic efficiency, and increased superoxide radical and reduced root growth at the early stages of seedling growth. Analysis of metabolite profiles revealed significant changes upon  ...[more]
