糖基神经酰胺是真核生物膜系统中重要的脂质成分。近年来的研究表明,GlcCers在调节真菌生长和发病机制中发挥着重要作用。在这项研究中,我们报道了PdGcs1基因的鉴定和功能表征,PdGcs1是指青霉基因组中编码GlcCer合成酶(GCS)的基因,GCS是GlcCer生物合成所必需的。研究表明,PdGcs1基因的缺失导致了指状地黄GlcCer (d18:1/18:0 h)和GlcCer (d18:2/18:0 h)的完全丧失,植被生长和产孢减少,孢子萌发延迟。PdGcs1缺失突变体对柑橘果实的毒力也受到损害,表现为水浸泡损伤的发生延迟,损伤的形成尺寸变小。这些结果表明,PdGcs1是一个真正的GCS,通过控制GCS的生物合成,在调节指状假单胞菌的细胞生长、分化和毒力方面发挥重要作用。
Glucosylceramides (GlcCers) are important lipid components of the membrane systems of eukaryotes. Recent studies have suggested the roles for GlcCers in regulating fungal growth and pathogenesis. In this study, we report the identification and functional characterization of PdGcs1, a gene encoding GlcCer synthase (GCS) essential for the biosynthesis of GlcCers, in Penicillium digitatum genome. We demonstrated that the deletion of PdGcs1 in P. digitatum resulted in the complete loss of production of GlcCer (d18:1/18:0 h) and GlcCer (d18:2/18:0 h), a decrease in vegetation growth and sporulation, and a delay in spore germination. The virulence of the PdGcs1 deletion mutant on citrus fruits was also impaired, as evidenced by the delayed occurrence of water soaking lesion and the formation of smaller size of lesion. These results suggest that PdGcs1 is a bona fide GCS that plays an important role in regulating cell growth, differentiation, and virulence of P. digitatum by controlling the biosynthesis of GlcCers.
