Transcriptional changes in response to oxidative stress in combination with temperature extremes in rice


ABSTRACT: Genome wide expression profiles of 10-day-old seedlings in response to prior exposure with OS followed by heat stress or cold stress as well simultaneous exposure to OS along with HS/CS was done to study the transcriptional changes in response to combination of stresses. 10-day old rice seedlings were used for experiments. Transcript profiling was done in 10-day old rice seedling following oxidative Stress prior to High Temperature Stress (PO_HS) or Low Temperature Stress (PO_CS) and Oxidative Stress during High Temperature Stress (DO_HS)/ during Low temperature stress (DO_CS). Unstressed seedlings were used as control. For each condition, three biological replicates were processed in a similar manner for the microarray analysis.

Transcript expression profiles of rice seedlings were analyzed in response to (a) prior exposure with oxidative stress followed by heat or cold stress and (b) simultaneous exposure to oxidative stress along with heat stress or cold stress. The numbers of genes differentially regulated during stress combination of cold and oxidative stress as well as heat and oxidative stress treatments were higher when compared with the number of genes differentially regulated in response to individual stress co  ...[more]
