Evaluation of Cd2+ stress tolerance in transgenic rice overexpressing PgGPx gene that maintains cellular ion and reactive oxygen species homeostasis.

ABSTRACT: Non-essential toxic heavy metal like cadmium (Cd2+) interferes with the plant growth and development in many ways. Cd2+ travels via plant transportation system, specifically through xylem and may integrate into the food chain causing unfavorable condition in human health. Therefore, strategies to develop Cd2+ tolerance and less accumulation in the plant system require urgent attention. Peroxidase gene family is known for metal ions transportation including Cd2+ and thus plays an important role in ion homeostasis. Previously, we have reported the presence of a Cd2+ dependent functional peroxiredoxin from Pennisetum glaucum (PgGPx). The present study elucidates the role of this PgGPx against Cd2+ stress in rice. The transcript levels of PgGPx were found to be highly upregulated in response t
