开花植物的小孢子发生在有性生殖中起着重要作用。据报道，DEFECTIVE IN EXINE FORMATION1（DEX 1）是拟南芥外壁模式形成所必需的。然而，DEX 1在调节小孢子发育中的功能在很大程度上还不清楚。在这项研究中，我们表明，DEX 1是强烈表达的绒毡层通过使用RNA原位杂交。dex1小孢子从四分体中释放后退化败育。dex1突变体的胼胝质壁比野生型的薄，表明DEX 1影响花药发育过程中四分体阶段胼胝质的形成。 DEX1编码具有一个跨膜结构域、一个胞内结构域和一个胞外结构域的膜蛋白。总的来说，我们的研究结果表明，DEX 1是必不可少的小孢子发育，可能通过调节CalS5的表达。
Microsporogenesis in flowering plants plays important roles in sexual reproduction. It has been reported that DEFECTIVE IN EXINE FORMATION1 (DEX1) is essential for exine pattern formation in Arabidopsis thaliana. However, the functions of DEX1 in regulating microspore development are largely not understood. In this study, we show that DEX1 is strongly expressed in the tapetum by using RNA in situ hybridization. dex1 microspores were degenerated and aborted after release from the tetrads. The callose wall in tetrads was thinner in the dex1 mutant than in the wild type, suggesting that DEX1 affects callose formation at the tetrad stage during anther development. DEX1 encodes a membrane protein with one transmembrane domain, one intracellular domain and one extracellular domain. Collectively, our results demonstrate that DEX1 is essential for microspore development, possibly by regulating the expression of CalS5.
