Plant diseases significantly impact food security and food safety. It was estimated that food production needs to increase by 50% to feed the projected 9.3 billion people by 2050.

Article Synopsis
  • - Gummy stem blight (GSB) is a widespread disease affecting cucurbits, caused by a complex of three similar fungal species that show high resistance to fungicides and lack of resistant plant varieties.
  • - The pathogenic fungi belong to the genus Stagonosporopsis and can infect a variety of cucurbit species—37 hosts in total—along with some other plants like papaya.
  • - Symptoms of GSB include leaf spots, blighting, and cankers on stems, often accompanied by gummy exudates, with visible signs typically appearing within 3-12 days under suitable conditions.

Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. We investigated the genetic diversity and reproductive biology of Colletotrichum graminicola isolates which infect maize by sequencing the genomes of 108 isolates collected from 14 countries using restriction site-associated DNA sequencing (RAD-seq) and whole-genome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms revealed three genetic groups delimited by continental origin, compatible with short-dispersal of the pathogen and geographic subdivision.

is one of the most important genera of plant-pathogenic fungi in the world and arguably the world's most important mycotoxin-producing genus. species produce a staggering array of toxic metabolites that contribute to plant disease and mycotoxicoses in humans and other animals. A thorough understanding of the mycotoxin potential of individual species is crucial for assessing the toxicological risks associated with diseases.

Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. In 2013, the community voiced near unanimous support for a concept of that represented a clade comprising all agriculturally and clinically important species, including the species complex (FSSC). Subsequently, this concept was challenged in 2015 by one research group who proposed dividing the genus into seven genera, including the FSSC described as members of the genus , with subsequent justification in 2018 based on claims that the 2013 concept of is polyphyletic.
