Additional file 1: Figure S1. of Allelic variants of OsSUB1A cause differential expression of transcription factor genes in response to submergence in rice
The submergence tolerance locus Sub1 in rice. The Sub1 locus is located on rice chromosome 9 with a variable number of SUB1 genes. In different rice genotypes, SUB1A is either absent or present as different allele. (a). Introgression of the Sub1 locus into the rice variety IR64 (IR64-Sub1) enhanced survival after complete submergence. (b). The photo shows the IRRI demonstration field plot in the Philippines. Phenotyping for submergence tolerance can also be conducted by submerging plants grown in trays (inlay). The SUB1A-1 and SUB1A-2 alleles are both highly expressed in nodes of submerged plants but SUB1A-1 expression is higher in internodes. (c). Schematic illustration based on (Singh et al., 2010).
