Transcriptome Analysis Reveals Photoperiod-Associated Genes Expressed in Rice Anthers.

Project description:Environmental conditions, such as photoperiod and temperature, can affect male fertility in plants. While this feature is heavily exploited in rice to generate male-sterile lines for hybrid breeding, the underlying molecular mechanisms remain largely unknown. In this study, we use a transcriptomics approach to identify key genes and regulatory networks affecting pollen maturation in rice anthers in response to different day lengths. A total of 11,726 differentially expressed genes (DEGs) were revealed, of which 177 were differentially expressed at six time points over a 24-h period. GO enrichment analysis revealed that genes at all time points were enriched in transport, carbohydrate, and lipid metabolic processes, and signaling pathways, particularly phytohormone signaling. In addition, co-expression network analysis revealed four modules strongly correlated with photoperiod. Within these four modules, 496 hub genes were identified with a high degree of connectivity to other photoperiod-sensitive DEGs, including two previously reported photoperiod- and temperature-sensitive genes affecting male fertility, Carbon Starved Anther and UDP-glucose pyrophosphorylase, respectively. This work provides a new understanding on photoperiod-sensitive pollen development in rice, and our gene expression data will provide a new, comprehensive resource to identify new environmentally sensitive genes regulating male fertility for use in crop improvement.

Transcriptome profiling reveals the regulatory role of CSA-mediated photoperiod-dependent male fertility

Project description:The discovery of photoperiod-sensitive male genic sterile (PGMS) lines started the development of two-line hybrid rice, which is critical to sustain production of high-yielding hybrid rice varieties. Previous reports about the PGMS lines are mainly focused on the gene cloning and their function description. The mechanisms by which PGMS lines perceive changes in photoperiod and transmit those signals to elicit downstream effects is rarely mentioned. In this work, we described the effects of photoperiod on gene expression in wild type (WT) and csa, a PGMS line, flag leaves and anthers to identify putative central factors that transduce photoperiod signals via CSA in both leaves and anthers. We also dissect the potential mechanisms that: cause csa-induced sterility under SD conditions; partially restore fertility in csa anthers under LD conditions; and finally, are responsible to restore full WT fertility under LD and SD conditions. These results provide an overview how the PGMS rice perceives and transmits photoperiod changes, and how the CSA and its homologs response to the environmental cues by regulating down-stream gene expression. That will be helpful to understand the photoperiod-sensitive mechanism and identify new photoperiod-sensitive genes.

Protein acetylation landscape of developing rice anthers

Project description:Protein lysine acetylation (KAC) is a dynamic and reversible post-translational modification, playing important biological roles in many organisms.Here, we reported results from a proteomic investigation to detect KAC status of the developing rice anthers near the time of meiosis (RAM), providing strong biochemical evidence for roles of many KAC-affected proteins during rice anther development and meiosis. We identified a total of 1,354 KAC sites in 676 proteins.

The transcriptome of anthers of rice gamyb mutant expressing various GAMYB homologs was measured at the microspore stage.

Project description:To confirm the function of the GAMYB homologs for Selaginella moellendorffii and Physcomitrella patens in rice cells, we examined the expression profile in the anthers of transgenic plants, which OsGAMYB, SmGAMYB, or PpGAMYB2 is expressed under the control of the rice GAMYB promoter in rice gamy mutant.
