Rice Gene Expression Analysis In Response To Two Kind Of Flood Stresses Using 22K Rice Oligo Microarray

Abstract

Global expression profiles of the flood stresses, standing (FS) and lay down (FD) were analyzed using 22K rice oligo microarray. Combined results from two flood stresses revealed 1,166 genes with greater than 2-fold change over (Up regulation) or less than 0.5-fold change over (Down regulation) control. Numbers of genes after each stress treatment (24hr) is as follows, 962 genes (5%) were changed in FS and 469 genes (2.3%) were in FD. Commonly up-regulated genes in both two flood stresses were 130 genes, including peroxidase and glucose biosynthesis etc. Commonly down-regulated genes were 132 genes, including nitrate reductase and transcription factor-like gene etc. Results of cis-element analyze and the related transcription factors will be presented.
