Abstract

Abstract A highly virulent Colletotrichum falcatum pathotype (CF08) was cultured in nutrient deficit media with fine-cut sugarcane stalks of red rot susceptible variety (CoJ 64). The mycelium was collected for the analysis of whole proteome using LCMS/MS. In-silico analysis was performed to identify the exclusive and differentially abundant proteins from whole proteomes of C. falcatum samples cultured with sugarcane (CFS1 and CFS2). Whole proteome analysis revealed a relatively higher number of peptide identities/proteins in CFS2 (2233), followed by CFS1 (1911), and CFC (control) with least number of proteins (1808). Compared to control, CFS1 and CFS2 samples of C. falcatum had plenty of exclusively abundant proteins like ABC transporters, glucose transporter, actin cytoskeleton-regulatory complex proteins, antimicrobial peptides, autophagy-related proteins, chitin synthase, dicer-like proteins, histone-lysine N-methyltransferase proteins, myosin-1 proteins, polyketide synthase proteins, and nonribosomal peptide synthase proteins which are involved in the process of fungal virulence/pathogenicity. In this manuscript, we report the first draft of C. falcatum proteome (whole proteome) which has been successfully submitted to ProteomeXchange Consortium via the PRIDE partner repository with the dataset identifier PXD033368.
