Expression of the putative imprinted genes is interrupted by heat stress. A, Expression-level fold changes (FC) of the putative imprinted genes between 48 and 72 HAF under normal control (CK), moderate stress (MS), and severe stress (SS) conditions. B, Expression of the putative imprinted gene OsFBL36 is activated in transgenic lines overexpressing OsFIE1, a known rice imprinted gene. C, Expression-level response of OsFBL36 to 2°C increments in temperature at 48 HAF. D, Expression profile of OsFBL36 in different tissues. Error bars indicate sd.
