Heat maps of expression data of genes involved in the ABA signal transduction pathway in inferior grains of rice subjected to soil drying during grain filling. The indica rice variety YD6 (YD) was used and plants were either well-watered controls (CK) or subjected to moderate drying (MD) of the soil. Samples were taken at 12 d after anthesis (DAA), 18 DAA, and 24 DAA. The maps were plotted using the value of RPKM for each gene in the different samples: blue indicates low values, red indicates high values
