摘要:

大规模生产大豆杂交种,利用杂种优势是种质资源创新与品种改良关键所在。通过挖掘和利用大豆雄性不育基因,能够培育出更具优势的大豆品种,从而提升大豆的产量和品质。选用宝泉岭绿大豆(母本)与黑农44(父本)杂交后代出现的雄性不育突变群体作为试验材料。选取大豆可育植株与不育植株的花蕾,对花药与花粉进行细胞学观察,并采用高通量测序平台对大豆可育植株与不育植株的花与花药组织进行转录组测序,对测序结果进行注释、筛选与分析。结果表明,不育植株的绒毡层发育异常,花粉高度不育,是导致雄性不育的重要原因。戊糖和葡萄糖醛酸相互转化途径(ko00040:Pentose and glucuronate interconversions)是影响大豆育性的关键通路,编码果胶甲酯酶(PEM)与果胶裂解酶(PL)基因呈下调表达。差异表达基因蛋白质互作网络表明,果胶裂解酶基因是影响戊糖和葡萄糖醛酸相互转化途径的关键基因。通过对果胶裂解酶含量的测定表明,不育植物花药中果胶裂解酶含量显著降低。qRT-PCR检测结果与RNA-Seq测序结果一致。推测这些基因的下调表达可能引起果胶裂解酶活性下降,从而影响绒毡层发育,导致雄性不育。

Abstract:

The large-scale production of soybean hybrids and the utilization of hybrid vigor are key to germplasm resource innovation and variety improvement.By mining and utilizing soybean male sterility genes,more advantageous soybean varieties can be cultivated,thereby improving soybean yield and quality.This study selected the male sterile mutant population that appeared in the hybrid offspring of Baoquanling green soybean(female parent)and Heinong 44(male parent)as the experimental material.Flower buds were selected from soybean fertile and sterile plants,the anthers and pollen cytology were observed,and a high-throughput sequencing platform was used to perform transcriptome sequencing on the flower and anther tissues of soybean fertile and sterile plants.Annotated,screened and analyzed the sequencing results.The results indicated that abnormal development of the tapetum layer and high pollen sterility in sterile plants were important causes of male infertility.The pentose and glucuronate interconversion pathway(ko00040:Pentose and glucuronate interconversion)was a key pathway affecting soybean fertility,and the genes encoding pectin methylesterase(PEM)and pectin lyase(PL)were downregulated in expression.The differentially expressed gene protein interaction network indicated that the pectin lyase gene was a key gene affecting the interconversion pathway between pentose and glucuronic acid.The determination of pectin lyase content showed that the pectin lyase content in sterile plant anthers was significantly reduced.The qRT-PCR detection results were consistent with the RNA-Seq sequencing results.It is speculated that the downregulation of these genes may cause a decrease in pectin lyase activity,thereby affecting the development of the tapetum and leading to male infertility.

Key words: Soybean, Male infertility, Transcriptomics, Tapetum, Pectate lyase
