(A) The iodine-stained cross-sections of the anthers at different developmental stages used in the real-time RT-PCR. Bars=0.1 mm. (B) Transcript levels of OsSUT1 and OsSUT3 in the pollen at different developmental stages. The transcript levels the SUT genes determined by real-time RT-PCR were standardized against those of a constitutive ubiquitin gene RUBIQ1 and expressed on a logarithmic scale. Values are the means of three independent replications (bars indicate SE). See Materials and methods for the details of the developmental stage. (This figure is available in colour at JXB online.)
