Abstract
Stamens,the male reproductive organs of plants,are essential to plant reproduction and crop yield. Although light signals affect reproductive development of Arabidopsis thaliana, little is known about its mechanism. HEMERA (HMR) is one of the key members of phytochrome signaling pathways. It plays an important role in the photomorphogenesis process by mediating the subcellular localization of phytochrome B (PhyB) and the degradation of PIFs. However,whether it is required for reproductive development is still not clear. In this study, we showed that the hmr mutant exhibited decreased anther size and pollen number, reduced pollen germination rate,and partial vacuolizated tapetum cells. In addition, the HMR-HA transgenic plants restored all these fertility defects and presented phenotype similar to the wildtype.
