Transcription profiling of Arabidopsis wild type and hfr1/sics1 knock-out mutant seedlings exposed to low R/FR light

ABSTRACT: Aim of the experiment is the identification of genes differentially regulated in hfr1/sics1 seedlings relative to wild type after prolonged exposure to low R/FR. To this end, gene expression changes were analysed in Arabidopsis wild-type and hfr1/sics1 knock-out mutant seedlings exposed to low R/FR light. The experiment was designed to enable comparison between the different genotypes exposed or not exposed to low R/FR light.

Shade-intolerant plants perceive the reduction in the ratio of red light (R) to far-red light (FR) as a warning of competition with neighboring vegetation and display a suite of developmental responses known as shade avoidance. In recent years, major progress has been made in understanding the molecular mechanisms underlying shade avoidance. Despite this, little is known about the dynamics of this response and the cascade of molecular events leading to plant adaptation to a low-R/FR environment.  ...[more]
