The wheat gene WPK4 encodes a 56-kDa protein kinase that belongs to group 3 of the SNF1-related protein kinase family (SnRK3), and is up-regulated by light and cytokinins and down-regulated by sucrose. In order to determine whether or not this particular regulation pattern is general among plant species, we isolated and characterized homologous genes from rice and maize. Two rice genes, OsPK4 and OsPK7, encode proteins comprising 508 and 520 amino acids, and show, respectively, 75% and 76… CONTINUE READING
