Relative expression levels of selected genes from the Heterosis-Related GeneDatabase exhibiting more than 90%homology with sorghum were studied in hybrids and their respective parental lines for a better understanding on the molecular basis of heterosis. A high (27A × RS 673) and a low heterotic hybrid (7A × CB 26) of sorghum along with their parental lines were used for this purpose. Twenty (15 maize and 5 rice) genes exhibiting more than 90% homology with that of sorghum were identified. The maize genes ZmHG13, ZmHG16, and ZmhG19 exhibited more than fourfold increase over the male parent (RS 673) of high heterotic hybrid during booting stage, which started decreasing during flowering stage. Similarly, the rice genes OsHG1 and OsHG12 recorded > 2.5-fold increase. However, these genes recorded less than twofold increase during the same stage of the plant in the low heterotic hybrid. Notably, among the genes that exhibited higher expression in the highly heterotic hybrid were those coding for proteins, which were known to play crucial roles in the manifestation of heterosis in plants.
