Whole-Genome Sequencing of Pathogenic Nigrospora musae ST1 Causing Leaf Spot Disease in Idesia polycarpa
Yun-Ze Chen, Yan Chen, Jing Yang
TL;DR
This study sequenced the genome of Nigrospora musae ST1, a new leaf spot pathogen in Idesia polycarpa, to better understand its pathogenicity and guide disease control.
Contribution
The first whole-genome sequencing of Nigrospora musae ST1, revealing pathogenicity-related genes and evolutionary insights.
Findings
The genome of N. musae ST1 contains 12,063 protein-coding genes, including those related to pathogenicity and carbohydrate metabolism.
Six secreted carbohydrate-active enzymes were identified as potentially important for plant pathogenicity.
Comparative analysis revealed genome rearrangements distinguishing N. musae ST1 from other Nigrospora species.
Abstract
Nigrospora musae ST1 is a newly identified pathogen responsible for leaf spot disease in Idesia polycarpa. In order to further advance our understanding of this strain and improve management strategies for the leaf spot disease, the PacBio Sequel II platform was used to perform whole-genome sequencing of N. musae ST1. The assembled genome comprised 42 contigs, with a total length of 49,259,803 bp and an average GC content of 56.23%. Functional annotation identified 12,063 protein-coding genes, including 125 Transporter Classification Database (TCDB)-related genes, 3600 pathogen host interaction (PHI) genes, 2503 Virulence Factor Database (DFVF)-related genes, and 722 genes encoding carbohydrate-active enzymes (CAZymes). Integrated analyses of the secretome, PHI, and DFVF databases revealed six secreted carbohydrate-active enzymes implicated in plant pathogenicity, including three…
