Identification of a class of CFEM proteins containing a new conserved motif in Fusarium oxysporum

摘要: Abstract Fusarium oxysporum (Fo) is an important soil-borne fungus that cause huge economic losses worldwide. Fungal-specific C ommon in F ungal E xtracellular M embrane (CFEM) proteins are known to be involved some physiological processes associated with pathogenicity. To date, few Fo CFEM have been characterized. The recent publication of several genomes has allowed us conduct a genome-wide comparison analysis Fo. In this study, we identified for 12 different formae speciales(f. sp) and obtained average 16 each were classified into three groups (groups 1–3) according structural features. Importantly, new conserved motif containing about 50 amino acids (DR motif) group 1 members. DR (CFEM_DR proteins) remarkably among Fo, their number greater compared other fungi. We found the expansion CFEM_DR can attributed segmental duplications genomes. Expression revealed genes had higher expression level mycelium than conidia, expressions increased dramatically host roots at 3 days post inoculation, indicating roles while colonizing infecting hosts.
