Abstract:

A full-length Cdna of cab gene was cloned from the first strand of bamboo(Bambusa oldhamii) cDNA through RT-PCR and RACE methods, named as cab-BO1 (cab gene from B. oldhamii). The length of cab-BO1(GenBank accession number:EF061137) is 1 102 bp,which contains an open reading frame encoding 265 amino acids from 64 th to 861 th position. The bioinformatics analysis indicated that the protein encoded by cab-BO1 has a chlorophyll a/b binding domain(64th232th position),a protein kinase C phosphorylation site (9th~11th position), a ubiquitin domain signature (27th~52th position),and a casein kinase II phosphorylation site(55th~58 th position). The DNA sequence and encoding amino acid sequence of cab-BO1 showed high similarity with the cab genes of Triticum aestivum,Musa acuminata,Zea mays and Oryza sativa, more than 85% and 89% repectively. The result indicates a clue that cDNA of cab family genes are conserved.
