AI Article Synopsis
- Banana is a major global fruit crop, with 145 million metric tons produced in 2011, primarily in over 130 countries, generating $44 billion.
- Fusarium wilt, or Panama disease, caused by Fusarium oxysporum f. sp. cubense, poses significant threats to banana production, particularly against the predominant Cavendish variety, which accounts for about 45% of the world's banana supply.
- While management strategies exist, they mainly focus on preventing the spread of the pathogen and using resistant cultivars, but resistance remains inadequate, especially in key dessert and cooking types.
Article Abstract
Banana (Musa spp.) is one of the world's most important fruits. In 2011, 145 million metric tons, worth an estimated $44 billion, were produced in over 130 countries. Fusarium wilt (also known as Panama disease) is one of the most destructive diseases of this crop. It devastated the 'Gros Michel'-based export trades before the mid-1900s, and threatens the Cavendish cultivars that were used to replace it; in total, the latter cultivars are now responsible for approximately 45% of all production. An overview of the disease and its causal agent, Fusarium oxysporum f. sp. cubense, is presented below. Despite a substantial positive literature on biological, chemical, or cultural measures, management is largely restricted to excluding F. oxysporum f. sp. cubense from noninfested areas and using resistant cultivars where the pathogen has established. Resistance to Fusarium wilt is poor in several breeding targets, including important dessert and cooking cultivars. Better resistance to this and other diseases is needed. The history and impact of Fusarium wilt is summarized with an emphasis on tropical race 4 (TR4), a 'Cavendish'-killing variant of the pathogen that has spread dramatically in the Eastern Hemisphere.

strain PJH16, isolated and tested by our team, suppresses cucumber wilt as an efficient biocontrol agent. For further investigation, the strain has been combined with two other ( VJH504 and JNF2) to enhance biocontrol ability, which formed high-efficiency microbial agents in the current study. The methodological target taken is based on achieving the optimal growth conditions of the combined microbial agents; hence, the medium composition and culture conditions were optimized through a single-factor test, orthogonal test and response surface methodology.

With the aim of enhancing plants' ability to respond to pathogenic fungi, this study focuses on disease resistance genes. We commenced a series of investigations by capitalizing on the pronounced differences in resistance to Fusarium wilt between resistant and susceptible varieties. Through an in-depth exploration of the metabolic pathways that bolster this defense, we identified genes associated with resistance to f.
