Cloning of a new glutathione peroxidase gene from tea plant (Camellia sinensis) and expression analysis under biotic and abiotic stresses.

ABSTRACT:

Background

Tea plant, Camellia sinensis (L.) O. Kuntze, a well-known heavy metal hyperaccumulator, possesses a powerful tolerance to heavy metals. The heavy metal stresses lead to reactive oxygen species (ROS) production, and high concentration of ROS is harmful to plants. The glutathione peroxidase gene has positive function to damage induced by ROS. To understand the mechanism of tolerance to deferent stresses in tea plant, a new glutathione peroxidase gene of tea plant was cloned and its expression pattern was analyzed under abiotic and biotic stresses.

Results

A novel cDNA encoding glutathione peroxidase of tea plant (Camellia sinensis) was isolated by rapid amplification of cDNA ends (RACE) method and designated as CsGPX2 (GenBank Accession No. JQ247186). This full-leng
