Functions of the Arabidopsis RLCK VI_A2 kinase in photomorphogenesis

The T-DNA insertion mutant of the ROP GTPase-binding Arabidopsis RLCK VI_A2 kinase exhibits limited cell and organ growth that interferes with skotomorphogenesis (morphogenesis under dark). Transcriptomic analysis was used to identify the cellular and developmental pathways affected by the absence of the kinase in seedlings grown under dark for 18-days.
