Reduced Sensitivity to Red Light in TIR-NBS-LRR Mutants.
(A) T-DNA insertion alleles in CSA1 (csa1-2) and other TIR-NBS-LRR loci show reduced inhibition of hypocotyl growth under red light.
(B) Expression levels of CSA1, RPS4, and AT5g44870 determined by RT-PCR in wild-type and T-DNA insertion mutants. T-DNA insertion sites for each mutant are shown.
