(This figure is accessible in colour at JXB on the net.)necessary for pollen germination and pollen tube development. When OsAP65 was disrupted, this substrate may not be degraded within a timely manner, resulting in impaired pollen germination and pollen tube growth. On the other hand, the physiological function of OsAP65 will not be completely clear until its substrates are recognized. A latest posting showed that two rice AP genes, OsAP25 and OsAP37, that have been promoted by ETERNAL TAPETUM one, trigged programmed cell death in tapetal cells in rice anthers (Niu et al., 2013). OsAP65 could take part in a molecular pathway triggering male sterility within the identical way as OsAP25 and OsAP37. Nonetheless, the existing success show a important function for OsAP65 in fertilization by way of its function in pollen tube growth, but not pollen maturation.AcknowledgementsWe thank Dr Gynheung An (POSTECH, Korea) for delivering the mutants, Dr Liwen Jiang (The Chinese University of Hong Kong, Hong Kong, China) for giving the PVC marker plasmid RFP tVSR2 and also the Golgi marker plasmid Man1 FP, and Dr Jian Xu (Huazhong Agricultural University, China) for delivering the the mitochondrial marker plasmid F1-ATPase-:RFP.
