为探讨巴氏蘑菇子实体不同发育阶段基因的表达情况,本研究对巴氏蘑菇子实体不同发育时期(原基、采收期和开伞期)进行转录组测序,以本实验室已获得的巴氏蘑菇JA菌株的不育单孢菌株JA-15036基因组为参考基因组研究原基与采收期及开伞期样本间差异表达基因,并对差异表达基因进行了GO功能和Pathway富集分析。GO功能分析结果显示,差异表达基因主要富集在跨膜转运、碳水化合物代谢途径和膜组分,它们协同调控为子实体生长发育提供稳定的内环境。KEGG富集分析结果表明,原基期上调的差异表达基因主要富集在核糖体蛋白和DNA复制,表明原基期细胞代谢旺盛,其中核糖体蛋白基因上调为后期蛋白质合成提供重要场所;采收期和开伞期子实体时期差异表达基因主要富集在碳水化合物代谢、脂肪酸降解和氨基酸代谢等途径,为巴氏蘑菇子实体的生长发育与成熟提供营养与能量。 相似文献

Plant stature is one important factor that affects the productivity of peach orchards. However, little is known about the molecular mechanism(s) underlying the dwarf phenotype of peach tree. Here, we report a dwarfing mechanism in the peach cv. FenHuaShouXingTao (FHSXT). The dwarf phenotype of ‘FHSXT’ was caused by shorter cell length compared to the standard cv. QiuMiHong (QMH). ‘FHSXT’ contained higher endogenous GA levels than did ‘QMH’ and did not response to exogenous GA treatment (internode elongation). These results indicated that ‘FHSXT’ is a GA‐insensitive dwarf mutant. A dwarf phenotype‐related single nucleotide mutation in the gibberellic acid receptor GID1 was identified in ‘FHSXT’ (GID1cS191F), which was also cosegregated with dwarf phenotype in 30 tested cultivars. GID1cS191F was unable to interact with the growth‐repressor DELLA1 even in the presence of GA. ‘FHSXT’ accumulated a higher level of DELLA1, the degradation of which is normally induced by its interaction with GID1. The DELLA1 protein level was almost undetectable in ‘QMH’, but not reduced in ‘FHSXT’ after GA3 treatment. Our results suggested that a nonsynonymous single nucleotide mutation in GID1c disrupts its interaction with DELLA1 resulting in a GA‐insensitive dwarf phenotype in peach. 相似文献
