DNA Sequence-Based Identification ofFusarium: A Work in Progress

Plant Disease, Journal Year: 2021, Volume and Issue: 106(6), P. 1597 - 1609

Published: Dec. 15, 2021

Accurate species-level identification of an etiological agent is crucial for disease diagnosis and management because knowing the agent's identity connects it with what known about its host range, geographic distribution, toxin production potential. This particularly true in publishing peer-reviewed reports, where imprecise and/or incorrect identifications weaken public knowledge base. can be a daunting task phytopathologists other applied biologists that need to identify Fusarium particular, published ongoing multilocus molecular systematic studies have highlighted several confounding issues. Paramount among these are: (i) this agriculturally clinically important genus currently estimated comprise more than 400 phylogenetically distinct species (i.e., phylospecies), 80% discovered within past 25 years; (ii) approximately one-third phylospecies not been formally described; (iii) morphology alone inadequate distinguish most from one another; (iv) current rapid discovery novel fusaria pathogen surveys accompanying impact on taxonomic landscape expected continue well into foreseeable future. To address critical accurate identification, our research groups are focused populating two web-accessible databases (FUSARIUM-ID v.3.0 nonredundant National Center Biotechnology Information nucleotide collection includes GenBank) portions three informative genes TEF1, RPB1, RPB2) resolve at or near level every species. The objectives Special Report, companion issue (Torres-Cruz et al. 2022), provide progress report efforts populate outline set best practices DNA sequence-based fusaria.

Diversity, Ecological Characteristics and Identification of Some Problematic Phytopathogenic Fusarium in Soil: A Review

Diversity, Journal Year: 2023, Volume and Issue: 15(1), P. 49 - 49

Published: Jan. 1, 2023

The genus Fusarium includes many pathogenic species causing a wide range of plant diseases that lead to high economic losses. In this review, we describe how the taxonomy has changed with development microbiological methods. We specify ecological traits and methods its identification in soils, particularly detection phytopathogenic representatives mycotoxins produced by them. negative effects soil-borne on agricultural plants current for control are discussed. Due complexity polymorphism species, integrated approaches risk assessment necessary.

Fusarium Dry Rot of Garlic Bulbs Caused by Fusarium proliferatum: A Review

Horticulturae, Journal Year: 2022, Volume and Issue: 8(7), P. 628 - 628

Published: July 12, 2022

Fusarium dry rot (FDR) is a postharvest disease of garlic crops causing yield losses worldwide. proliferatum has been identified as the main species disease. Symptoms begin small brown lesions with dehydrated appearance that can progress to cover entire clove during storage period. on growing plants cause basal plates and roots, sometimes damping-off observed. F. polyphagous pathogen wide range hosts. This colonizes remaining latent pathogen, develops storage. The overwinter in soil, infested crop residues, weeds. fungus also persist cloves, acting primary inoculum field contributing long-distance spread. Using healthy plant material, rotating crops, burying avoiding bulb injury harvest subsequent handling, providing appropriate environmental conditions are crucial factors greatly influence severity. Choosing suitable non-host achieve truly effective rotation difficult. Chemical control form seed treatments or spraying limited effect controlling FDR. Field applications biological agents have shown some efficacy, but optimize their activity must be determined. Moreover, different soil management strategies reduce studied.
