    Abstract

    A cDNA encoding putative phospholipid hydroperoxide glutathione peroxidase (PHGPX) was isolated from rice using rapid amplification of cDNA ends. This cDNA, designated ricPHGPX, includes an open reading frame encoding a protein of 169 amino acids which shares about 60% and 50% amino acid sequence identity with plant and mammalian PHGPXs, respectively. The gene is expressed at a relative high level in flag leaves and the expression can be markedly induced by oxidative stress, suggesting that the product of the gene plays a key role in defense against oxidative damage in rice.
