Dynamics of gene expression associated with arsenic uptake and transport in rice during the whole growth period.

ABSTRACT:

Background

Genes associated with arsenite uptake and transport in rice plants (i.e., OsLsi1, OsLsi2, OsLsi3, OsLsi6 and OsABCC1) have been identified to date. However, their expression over time during the whole growth period of rice under arsenite stress conditions is still poorly understood. In this study, the dynamics of gene expression associated with arsenite transport and arsenic concentrations in different organs of rice were investigated to determine the critical period(s) of arsenite uptake and translocation regulated by gene expression during the whole growth period.

Results

The relative expression of OsLsi2 and OsLsi1 in the roots was upregulated and reached its highest value (2^-∆∆Ct = 4.04 and 1.19, respectively) at the jointing stage (9 weeks after tr
