To investigate the molecular mechanism of high-temperature all-stage stripe rust resistance in Xiaoyan 6, an E3 ubiquitin ligase gene, TaPUB23, was identified based on the previous transcriptome sequencing results. This gene, which was significantly upregulated under both stripe rust infection and high-temperature conditions, has a full-length sequence of 1,272 bp, encoding 423 amino acids, and is localized in the cell membrane, cytoplasm, and nucleus. Virus-induced transient overexpression of TaPUB23 significantly reduced the stripe rust resistance of Xiaoyan 6 plant. Based on the yeast two hybrid (Y2H) system, we identified the interaction target TaDJA7 of TaPUB23 and demonstrated that TaPUB23 ubiquitinated TaDJA7. The interaction between TaPUB23 and TaDJA7 was further validated through luciferase complementation assays (LCA), bimolecular fluorescence complementation (BiFC), and Pull-down assays. These findings reveal that the E3 ubiquitin ligase TaPUB23 regulates high-temperature all-stage stripe rust resistance in wheat through ubiquitination of TaDJA7.

为探究小麦品种小偃6号高温全生育期抗条锈性分子机理,基于前期转录组测序结果,筛选到1个在条锈菌侵染及温度双重诱导下表达量显著上调的E3泛素连接酶基因TaPUB23,其序列全长1 272 bp,编码423个氨基酸,定位于细胞膜、细胞质和细胞核。病毒介导TaPUB23瞬时过表达能显著降低小偃6号植株对条锈病的抗性。利用酵母双杂交筛选到TaPUB23的互作靶标TaDJA7,TaPUB23可对靶标进行泛素化修饰,进一步通过荧光素酶互补(LCA)、双分子荧光互补(BiFC)及Pull-down试验验证了其互作关系。以上结果说明E3泛素连接酶TaPUB23通过泛素化修饰TaDJA7,从而调控小麦的高温抗锈性过程。

为探究小麦品种小偃6号高温全生育期抗条锈性分子机理,基于前期转录组测序结果,筛选到1个在条锈菌侵染及温度双重诱导下表达量显著上调的E3泛素连接酶基因TaPUB23,其序列全长1 272 bp,编码423个氨基酸,定位于细胞膜、细胞质和细胞核。病毒介导TaPUB23瞬时过表达能显著降低小偃6号植株对条锈病的抗性。利用酵母双杂交筛选到TaPUB23的互作靶标TaDJA7,TaPUB23可对靶标进行泛素化修饰,进一步通过荧光素酶互补(LCA)、双分子荧光互补(BiFC)及Pull-down试验验证了其互作关系。以上结果说明E3泛素连接酶TaPUB23通过泛素化修饰TaDJA7,从而调控小麦的高温抗锈性过程。

To investigate the molecular mechanism of high-temperature all-stage stripe rust resistance in Xiaoyan 6, an E3 ubiquitin ligase gene, TaPUB23, was identified based on the previous transcriptome sequencing results. This gene, which was significantly upregulated under both stripe rust infection and high-temperature conditions, has a full-length sequence of 1,272 bp, encoding 423 amino acids, and is localized in the cell membrane, cytoplasm, and nucleus. Virus-induced transient overexpression of TaPUB23 significantly reduced the stripe rust resistance of Xiaoyan 6 plant. Based on the yeast two hybrid (Y2H) system, we identified the interaction target TaDJA7 of TaPUB23 and demonstrated that TaPUB23 ubiquitinated TaDJA7. The interaction between TaPUB23 and TaDJA7 was further validated through luciferase complementation assays (LCA), bimolecular fluorescence complementation (BiFC), and Pull-down assays. These findings reveal that the E3 ubiquitin ligase TaPUB23 regulates high-temperature all-stage stripe rust resistance in wheat through ubiquitination of TaDJA7.
