(in plants was significantly reduced. We exhibited that TEK negatively regulates expression after the tetrad stage in wild-type anthers and further discovered that premature TEK-GFP in directly represses expression through histone modification. Our findings show that TEK RQ-00203078 flexibly mediates its different functions via RQ-00203078 different temporal regulation, revealing that this temporal regulation of TEK is essential for exine patterning. Moreover, the result that this repression of by TEK after the tetrad stage coincides with the timing of callose wall dissolution suggests that tapetum utilizes temporal regulation of genes to stop callose wall synthesis, which, together with the activation of callase activity, achieves microspore release and pollen wall patterning. Author summary To develop into mature pollen grains, microspores require formation of the pollen wall. To date, pollen wall developmental events, including production and transportation of pollen wall components, synthesis and degradation of the callose wall, and deposition and demixing of primexine, have been studied in.
