Bin1/Amphiphysin/Rvs (BAR) domain-containing proteins mediate fundamental cellular processes, including membrane remodeling and endocytosis. Nematode-trapping (NT) fungi can differentiate to form trapping structures through highly reorganized cell membranes and walls. In this study, we identified the NT fungus ortholog of yeast Rvs167 and documented its involvement in membrane bending and endocytosis. We further confirmed that the deletion of makes the fungus more hypersensitive to osmotic salt (Nacl), higher temperatures (28 to 30 °C), and the cell wall perturbation agent Congo red. In addition, the disruption of reduced the trap formation capacity. Hence, may regulate fungal pathogenicity through the integrity of plasma membranes and cell walls.
含Bin1/Amphiphysin/Rvs(BAR)结构域的蛋白质介导包括膜重塑和内吞作用在内的基本细胞过程。捕食线虫(NT)真菌可通过高度重组的细胞膜和细胞壁分化形成捕食结构。在本研究中,我们鉴定了酵母Rvs167的NT真菌直系同源物,并记录了其参与膜弯曲和内吞作用。我们进一步证实,该基因的缺失使真菌对渗透盐(氯化钠)、较高温度(28至30°C)和细胞壁扰动剂刚果红更加敏感。此外,该基因的破坏降低了陷阱形成能力。因此,该基因可能通过质膜和细胞壁的完整性来调节真菌致病性。
