Abstract

Hydrophobins (HFBs) are a group of small, secreted amphipathic proteins of fungi with multiple physiological functions and potential commercial applications. In this study, HFB genes of the edible mushroom, , were systematically identified and characterized, and their transcriptional profiles during fungal development were determined. In total, 19 typical class I HFB genes were discovered and bioinformatically analyzed. Gene expression profile examination showed that was particularly highly upregulated during primordia formation, suggesting its major role as the predominant HFB in the lifecycle of . The wettability alteration profile and the surface modification ability of recombinant rGf.hyd9954 were greater than for the HFB HGFII-his. rGf.hyd9954 was also demonstrated to form the typical class I HFB characteristic-rodlet bundles. In addition, rGf.hyd9954 was shown to possess nanoparticle characteristics and emulsification activities. This research sheds light on the regulation of fungal development and its association with the expression of HFB genes.

摘要

疏水蛋白(HFBs)是一类由真菌分泌的小型两亲性蛋白质,具有多种生理功能和潜在的商业应用价值。在本研究中,对食用菌的HFB基因进行了系统鉴定和表征,并确定了其在真菌发育过程中的转录谱。总共发现了19个典型的I类HFB基因,并进行了生物信息学分析。基因表达谱检测表明,在原基形成过程中特别高度上调,表明其作为生命周期中主要HFB的主要作用。重组rGf.hyd9954的润湿性改变谱和表面修饰能力大于HFB HGFII-his。rGf.hyd9954也被证明能形成典型的I类HFB特征性杆状束。此外,rGf.hyd9954显示出具有纳米颗粒特性和乳化活性。本研究为真菌发育的调控及其与HFB基因表达的关联提供了线索。
