WebIn situ hybridization of floral buds showed that POD2/SlG-LecRK-II.9 is specifically expressed in tapetal cells and microspores at late tetrad stage. Accordingly, abnormalities in meiosis and tapetum programed cell death in pod2 occurred during microsporogenesis, which results in the formation of four dysfunctional microspores leading to an aberrant … WebProteins of the ARGONAUTE (AGO) family function in the epigenetic regulation of gene expression. Although the rice (Oryza sativa) genome encodes 19 predicted AGO proteins, few of their functions have thus far been characterized. Here, we show that the AGO protein OsAGO2 regulates anther development in rice. OsAGO2 was highly expressed in anthers. Web期刊：The Plant Cell ...
