(This figure is obtainable in colour at JXB online.)important for pollen germination and pollen tube growth. When OsAP65 was disrupted, this substrate is probably not degraded in a timely manner, resulting in impaired pollen germination and pollen tube growth. On the other hand, the physiological function of OsAP65 is not going to be totally clear until finally its substrates are identified. A current write-up showed that two rice AP genes, OsAP25 and OsAP37, that were promoted by ETERNAL TAPETUM one, trigged programmed cell death in tapetal cells in rice anthers (Niu et al., 2013). OsAP65 may well participate in a molecular pathway creating male sterility in the similar way as OsAP25 and OsAP37. Nonetheless, the existing results demonstrate a critical function for OsAP65 in fertilization through its function in pollen tube development, but not pollen maturation.AcknowledgementsWe thank Dr Gynheung An (POSTECH, Korea) for offering the mutants, Dr Liwen Jiang (The Chinese University of Hong Kong, Hong Kong, China) for supplying the PVC marker plasmid RFP tVSR2 and also the Golgi marker plasmid Man1 FP, and Dr Jian Xu (Huazhong Agricultural University, China) for offering the the mitochondrial marker plasmid F1-ATPase-:RFP.
