Fig. 7From: Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatmentsExpression patterns of PPR genes under the salt and drought salt stresses. (a) Heatmap showing different expression profiles of PPR genes in drought-tolerant (Nagina 22, N22) and salinity-tolerant (Pokkali, PK) rice cultivars with IR64 (susceptible cultivar) under the salt stress (SS) and drought stress (DS). (b) Expression levels of 4 genes under salt condition (S) after 12Â h, 24Â h, 48Â h and 72Â h. (c) The expression level of 4 genes under drought condition (d)Back to article page
