Light serves as a crucial environmental cue which modulates plant growth and development, is controlled by multiple photoreceptors including the primary red light photoreceptor, phytochrome B (phyB). The signaling mechanism of phyB involves direct interactions with group basic helix-loop-helix (bHLH) transcription factors, PHYTOCHROME-INTERACTING FACTORS (PIFs), negative regulators photomorphog...

From eggplant hypocotyl tissues we have cloned two closely related cDNAs encoding cytochromes P450 (P450s) by PCR amplification using a primer designed based on the highly conserved sequence among the known eggplant P450s. One cDNA lacks the NH2-terminal short sequence that is present in the other, full-length cDNA. The two predicted protein sequences are 71% identical with each other and show ...
