    Abstract:
    Fusarium oxysporum f. sp. cubense is one of the most destructive soilborne fungi causing Fusarium wilt disease in banana. Generally, F. oxysporum f. sp. cubense race 1 (R1) severely affects most of the banana varieties, except Cavendish banana (AAA). Here, we present the draft genome of an isolate of VCG 0124, a novel virulent R1 strain that severely affects the Cavendish group of banana isolated from the Theni district of Tamil Nadu, India. The genome assembly of R1 comprises 61,471,473 bp with 88 contigs and 18,377 protein-coding regions. The genome contains homologs of F. oxysporum f. sp. cubense race-specific secreted-in-xylem (SIX) genes SIX1, SIX5, SIX9, and SIX13. The absence of SIX4 and SIX6 and deletion of a peptide in SIX1 virulence factor genes in the R1 (VCG 0124) strain might be the contributing factor for strains infecting Cavendish banana in India.
