Abstract
This article deals with: Bananas: their origin and global rollout; genetic diversity of Fusarium oxysporum f.sp. cubense, the causal agent of Panama Disease; Panama Disease: history repeats itself; tropical race 4, a single pathogen clone, threatens global banana production; strategies for sustainable Panama Disease management.
Highlights
In the late 1960s, Panama disease emerged in Cavendish bananas in Taiwan, but Tropical Race 4 (TR4) was only identified as its cause in 1994 [9,24,25]
We showed that high-throughput genome analyses unveil Foc population diversity (Figs 1 and 2), rather than lengthy and cumbersome Vegetative compatibility group (VCG) analyses, which enables resistance deployment strategies
Commercially viable, and resistant banana cultivars reach markets, any potential disease management option needs to be scrutinized, thereby lengthening the commercial lifespan of contemporary banana accessions
Summary
In 1876, a wilting disease of banana was reported in Australia [7], and in 1890, it was observed in the “Gros Michel” plantation crops of Costa Rica and Panama [8,9]. Phenotyping has identified three Foc races (1, 2, and 4) that cause disease in different subsets of banana and PLOS Pathogens | DOI:10.1371/journal.ppat.1005197 Foc race designations are cumbersome and other methods unveiling genetic diversity were developed.
