A new AOX homologous gene OsIM1 from rice (Oryza sativa L.) with an alternative splicing mechanism under salt stress

A differentially expressed OsIM1 gene was isolated from rice salt-tolerant mutant M-20 by differential display. Sequence analysis revealed that the amino-acid sequence of OsIM1 showed 66% and 62% identity with PTOX from tomato (Capsicum annuum) and AtIM from Arabidopsis, both of which encoded chloroplast-orientated terminal oxidase. Comparison of the… CONTINUE READING
