Abstract

f. sp. is one of the most destructive soilborne fungi causing Fusarium wilt disease in banana. Generally, 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. sp. race-specific () genes , and . The absence of SIX4 and SIX6 and deletion of a peptide in virulence factor genes in the R1 (VCG 0124) strain might be the contributing factor for strains infecting Cavendish banana in India.

摘要

f. sp. 是一种最具破坏性的土传真菌，可引起香蕉枯萎病。通常，型 1 (R1) 严重影响大多数香蕉品种，但 Cavendish 香蕉 (AAA) 除外。在这里，我们展示了一个 VCG 0124 分离株的基因组草图，这是一种新型的强毒 R1 菌株，它严重影响了印度泰米尔纳德邦 Theni 区分离的 Cavendish 组香蕉。R1 的基因组组装由 61,471,473 bp 组成，有 88 个 contigs 和 18,377 个蛋白质编码区。基因组包含 f. sp. 种特异性 () 基因和的同源物。R1 (VCG 0124) 菌株中 SIX4 和 SIX6 的缺失以及毒力因子基因中一个肽的缺失可能是导致印度感染 Cavendish 香蕉的菌株的因素。
