Fusarium Wilt Management in Cotton Cultivation

Fusarium wilt, caused by the soilborne fungus Fusarium oxysporum f. sp. vasinfectum, poses a persistent threat to cotton production worldwide. The pathogen invades the root system and colonises the xylem vessels, leading to wilting, chlorosis and often plant death. Management strategies combine resistant cultivars, cultural practices and biological or chemical interventions. Resistant varieties remain the cornerstone of disease control, with ongoing efforts to identify and incorporate resistance genes against prevalent races. Crop rotation and soil amendments can suppress pathogen inoculum, while precise planting dates and optimal temperature regimes have been shown to minimise early‐season infection. Molecular diagnostics and high‐throughput sequencing have advanced understanding of pathogen diversity and virulence mechanisms, enabling the development of targeted resistance breeding programmes. Integration of agronomic measures with improved genetic resistance supports sustainable yield stability, particularly in regions with endemic Fusarium wilt. Recent studies emphasise the importance of coordinated approaches that link genotype evaluation with field management, underlining the global significance of Fusarium wilt management for food security and fibre production.

Research from Nature Portfolio

A long‐term field survey in a major cotton‐growing region documented temporal shifts in Fusarium and Verticillium wilt incidence, revealing that changes in cultivar deployment and climatic variables directly influenced disease prevalence over a fifteen‐year period. These findings underscore the dynamic nature of pathogen epidemics and the need for adaptive management plans that consider varietal turnover and weather patterns. In parallel, transcriptome profiling of sea‐island cotton lines with contrasting resistance levels uncovered a network of long noncoding RNAs (lncRNAs) that are differentially expressed upon Fusarium oxysporum challenge. This work highlighted lncRNAs as novel regulators of defence pathways, suggesting their potential utility as molecular markers in breeding programmes aimed at enhancing wilt resistance.

Technical terms

Forma specialis: A host‐specific category within Fusarium oxysporum that defines pathogenic variants infecting particular plant species.

Race: A subgroup of a plant pathogen distinguished by its ability to overcome specific host resistance genes.

Quantitative trait locus (QTL): A chromosomal region containing one or more genes that contribute to variation in a quantitative trait, such as disease resistance.

Long noncoding RNA (lncRNA): RNA molecules longer than 200 nucleotides that do not encode proteins but regulate gene expression and defence responses.

Hypersensitive response: A rapid, localized cell‐death reaction in plants that restricts pathogen spread by sacrificing infected cells.
