I have searched the public data at Genbank for rice P450s in the nr, htgs, gss and est sections. All P450 fragments have been identified and Blast searches have been done of all fragments against each other to identify overlapping fragments and assemble them into contigs. Currently there are 296 contigs. These are composed of 156 full length sequences and 45 pseudogene partial sequences that cannot be made any more complete. There are 95 more partial sequences that will need further work to complete. The 296 sequences have been made into a blast searchable file and they are now searchable on our blast server. The file of annotated sequences is available as well as the FASTA version without all the annotation. (see the rice section of the homepage).
