摘要: 前期研究中通过对秀珍菇经低温诱导后不同发育阶段样本进行转录组测序及差异表达基因分析发现,ID为Cluster-6377.64510的基因(命名为PpFBD1)在原基形成前期的样本中高表达。为进一步了解分析其表达特性及功能,根据转录组测序结果设计特异性引物,利用RT-PCR技术从秀珍菇中克隆获得了该基因的cDNA全长。该基因由342个核苷酸组成,编码一个由113个氨基酸组成的蛋白,蛋白相对分子质量约11 ku。进化树分析显示,PpFBD1编码蛋白与糙皮侧耳hydrophobin1编码的疏水蛋白亲缘关系最近。Gene Ontology功能分析表明,PpFBD1主要参与真菌类细胞壁的合成。荧光定量RT-PCR检测显示,该基因在菌丝体经低温诱导后恢复至室温阶段(原基形成前期)表达量最高,这表明其可能参与调控秀珍菇原基形成过程。本研究结果为阐明秀珍菇原基形成机制提供参考。

Abstract: Through transcriptome sequencing and differential expression gene analysis of Pleurotus pulmonarius samples at different developmental stages induced by low temperature in the previous study, it was found that the gene with ID Cluster-6377.64510 (named as PpFBD1) was highly expressed at the prophase of primordium formation. To further understand and analyze its expression characteristics and functions, the full-length cDNA sequences of PpFBD1 was cloned from Pleurotus pulmonarius by RT-PCR method with the specific primers designed based on transcriptome data. The PpFBD1 was composed of 342 nucleotides that encode a protein consisted of 113 amino acids. The relative molecular weight of this protein is about 11 ku. Phylogenetic tree analysis showed that the protein encoded by PpFBD1 had the closest relationship with hydrophobin1 of Pleurotus ostreatus. GO functional analysis showed that the PpFBD1 mainly involved in the synthesis of fungal cell walls. Fluorescence quantitative RT-PCR detection found that the expression of the gene was the highest in the phase of mycelium recovery to room temperature after induction at low temperature. It suggested that the gene may be involved in the regulation of primordium morphogenesis in Pleurotus pulmonarius. The results of this study provided a reference for elucidating the formation mechanism of the primordium of Pleurotus pulmonarius.
