Article Synopsis
- Fusarium pseudocircinatum is identified as the primary cause of big-leaf mahogany malformation disease (BLMMD) in mahogany trees in Mexico, significantly impacting this valuable timber species.
- The study assessed genetic diversity among F. pseudocircinatum isolates collected from 611 mahogany trees across four Mexican states, finding high overall genetic variability with 87 unique multilocus genotypes identified.
- The high genetic diversity (average 0.147) and significant variation within genotypes suggest ongoing genetic flow and possible historical dispersion routes, particularly between isolates from Colima and Michoacán.
Big-leaf mahogany (Swietenia macrophylla) is valued for its high-quality wood and use in urban landscapes in Mexico. During surveys of mango-producing areas in the central western region of Mexico, symptoms of malformation, the most important disease of mango in the area, were observed on big-leaf mahogany trees. The objectives of this research were to describe this new disease and determine its cause.
