“…The salicylic acid response and the production of PR1 have been previously identified as a key defense indicator differentiating Fusarium wilt resistant and susceptible banana cultivars (Van Den Berg et al, 2007 ; Wang et al, 2015 ; Ramu et al, 2016 ; Li et al, 2017 ; Zhang et al, 2019 , 2020 ). The exogenous application of salicylic acid has also been demonstrated to induce partial resistance to Fusarium wilt in bananas (Wang et al, 2015 ; Emilda et al, 2020 ). Systemic acquired resistance, in parallel with salicylic acid defense is likely controlled by the production of nitric oxide, itself controlled by N nutrition (Sun et al, 2020 ).…”

Nitrogen (N) fertilizers are routinely applied to bananas (Musa spp.) to increase production but may exacerbate plant diseases like Fusarium wilt of banana (FWB), which is the most economically important disease. Here, we characterized the effects of N rate and form on banana plant growth, root proteome, bacterial and fungal diversity in the rhizosphere, the concentration of Fusarium oxysporum f.sp. cubense (Foc) in the soil, and the FWB severity. Banana plants (Musa subgroup ABB) were grown under greenhouse conditions in soil with ammonium or nitrate supplemented at five N rates, and with or without inoculation with Foc. The growth of non-inoculated plants was positively correlated with the N rate. In bananas inoculated with Foc, disease severity increased with the N rate, resulting in the Foc-inoculated plant growth being greatest at intermediate N rates. The abundance of Foc in the soil was weakly related to the treatment conditions and was a poor predictor of disease severity. Fungal diversity was consistently affected by Foc inoculation, while bacterial diversity was associated with changes in soil pH resulting from N addition, in particular ammonium. N rate altered the expression of host metabolic pathways associated with carbon fixation, energy usage, amino acid metabolism, and importantly stress response signaling, irrespective of inoculation or N form. Furthermore, in diseased plants, Pathogenesis-related protein 1, a key endpoint for biotic stress response and the salicylic acid defense response to biotrophic pathogens, was negatively correlated with the rate of ammonium fertilizer but not nitrate. As expected, inoculation with Foc altered the expression of a wide range of processes in the banana plant including those of defense and growth. In summary, our results indicate that the severity of FWB was negatively associated with host defenses, which was influenced by N application (particularly ammonium), and shifts in microbial communities associated with ammonium-induced acidification.

Acclimatization is one of the important processes in banana micro propagation before plantlets/planting materials are ready to be cultivated in the field. Trichoderma sp. are well known as plant promoter fungi that can promote plant growth and increase survival rate of plantlets. The study was arranged in a Completely Randomized Factorial Design with two factors and four replications. The first factors was covering type i.e. 1) individual covering and 2) mass covering. The second factor was the proportion of Trichoderma addition into manure, namely A) manure without the addition of Trichoderma sp. (control), B) Trichoderma sp. : manure = 1 : 400 (w/w), C) Trichoderma sp. : manure = 1 : 800 (w/w) and D) Trichoderma sp. : manure = 1 : 1,200 (w/w). The purpose of this study was to investigate the effect of Trichoderma sp. applications and covering types in the growth of banana plantlets cv. Barangan during the acclimatization process. The results showed that the best treatment to induce plantlet growth during the acclimatization process was the addition of Trichoderma sp.: manure with 1 : 400 (w/w) proportion and individual covering. The combination of Trichoderma sp. : manure with 1 : 400 (w/w) proportion and individual covering produced plant height and leaf length 8.5 cm and 4.4 cm, respectively, compared to the treatment without Trichoderma sp. addition that produced plantlets with 6.6 cm height and 3.4 cm leaf length. No significant interaction was shown between Trichoderma sp. proportions and covering types on leaf width, the number of leaves and root length parameters.

Phylloplane fungi is a non-pathogenic fungi on the leaf surface that can be used to control plant diseases caused by pathogens. One of the most damaging banana plant diseases is fusarium wilt, caused by the pathogenic fungi Fusarium oxysporum f. sp. Cubense (Foc). Mangrove plant Rhizophora apiculate is widely distributed and is a high-diversity area where microorganisms that produce anti-microbial compounds flourish. This plant can be used as a biological agent. This study aims to determine the various phylloplane fungi available from mangrove plant R. apiculata leaves and their potential use against Fusarium oxysporum f. sp. cubense (Foc) in banana plants (Musa acuminata L.). All 20 phylloplane fungi were identified through DNA sequencing with identities of 83.88–100%; of those 20, 3 were found that have antagonistic potential against Fusarium oxysporum f. sp. cubense (Foc): Lasiodiplodia theobromae (67.43%), Trichoderma harzianum (66.65), and Nigrospora sphaerica (65.33%). In the in vivo tests, the best inhibition of disease incidence was shown by treatment with Lasiodiplodia theobromae (11.11%). The present study confirmed that phylloplane fungi isolated from R. apiculata can inhibit fusarium wilt disease in banana plant.
