“…Regardless of the application of conventional organic fertilizer or biofertilizer, both the pepper–banana and eggplant–banana rotations showed highly efficient suppression of banana Fusarium wilt disease via significant legacy effects of rotation crop‐unique core taxa. This observation agreed well with previous findings of the pineapple ( Ananas squamosa )‐banana rotation strategy to manage soilborne disease (Yuan et al ., 2021). Notably, significant inhibition of pathogens by biofertilizers was not observed, as reported previously (Fu et al ., 2017).…”

“…It is well known that to invade banana vascular tissue, pathogens must breach the defense line of the rhizosphere (Chapelle et al ., 2016) and compete with rhizosphere microbes for limited nutrient resources or available habitat niches (Philippot et al ., 2013). Crop rotation has been a proven agricultural practice to improve soil fertility and crop production (Zhao et al ., 2022), and it could also provide substantial antagonistic benefits, such as manipulating the rhizosphere soil community structure and function to form a shield for suppressing pathogens (Lupwayi et al ., 1998; Larkin, 2015; Tiemann et al ., 2015; Yuan et al ., 2021). Furthermore, the application of biofertilizer as a farming management practice has proven frequently effective for banana disease suppression via, for instance, providing beneficial microbes that directly antagonize the pathogen or indirectly stimulate the indigenous soil microbiome (Fu et al ., 2017).…”

Summary Crop rotation can assemble distinct core microbiota as functionally specific barriers against the invasion of banana Fusarium oxysporum pathogens. However, the taxonomic identity of rotation‐unique core taxa and their legacy effects are poorly understood under field conditions. Pepper and eggplant rotations were employed to reveal rotation crop‐ and banana‐unique antagonistic core taxa by in situ tracking of the soil microbiome assembly patterns for 2 yr. The rotation crop‐unique antagonistic taxa were isolated and functionally verified by culture‐dependent techniques, high‐throughput sequencing, and pot experiments. Pepper and eggplant rotations resulted in eight and one rotation‐unique antagonistic core taxa out of 12 507 microbial taxa, respectively. These nine antagonistic taxa were retained the following year and significantly decreased banana wilt disease incidence via legacy effects, although the cultivated strains were exclusively of the genera Bacillus and Pseudomonas. The fermentation broth and volatiles of these two taxa showed strong antagonistic activity, and pot experiments demonstrated high suppression of wilt disease and significant promotion of banana growth. Our study provides a mechanistic understanding of the identification of rotation crop‐unique antagonistic taxa and highlights the importance of targeted cultivation of beneficial microorganisms for optimizing crop rotation‐based scenarios in support of banana agriculture sustainability.

“…High-throughput sequencing and analysis were used to identify the taxa-specific bacteria with potential promoting strawberry growth. Potential promoting bacteria was isolated according to Yuan et al (2021) with slight modifications. Briefly, a total of 10 g of CarSt-FloB treatment soil was added to 90 mL of sterile water and shaken for 30 min.…”

Long‐term continuous cropping of strawberry induces soil degradation, which reduces strawberry growth and yield. Agricultural waste and microorganisms have great potential in improving soil health. The aim of this study was to identify the potential mechanisms of Bacillus velezensis containing agricultural waste to improve soil health. Soil that had been cropped continuously for more than 10 years was flooded with water for approximately 28 days. After flooding, agricultural waste fermented with microorganisms was applied to improve soil health. Microbial biofilm formation and rhizosphere colonization were also determined. Different agricultural waste coupled with pre‐flooding resulted in a significant increase of strawberry biomass by 33.0%–98.4% compared with control and changes in soil properties. The application of agricultural waste also significantly increased soil bacterial diversity, with the Shannon index increased by 2.37%–6.11% compared with control, and changed the bacterial community composition. The promotion of plant growth was linked with detectable shifts in the soil bacterial taxa after pre‐flooding and B. velezensis containing agricultural waste usage. Most importantly, random forest and correlated analyses showed that taxa affiliated with Pseudomonas may be important in strawberry growth after treatment. Subsequent bacterial isolation and pot inoculation experiments validated that co‐inoculation of Pseudomonas fluorescens and B. velezensis significantly promoted strawberry growth by 21.7% and 31.4%, respectively, compared with inoculation of only P. fluorescens or only B. velezensis, thus confirming the beneficial effect on strawberry plant growth in continuous cropped soils. Our results also indicate that co‐culture of P. fluorescens and B. velezensis could enhance biofilm formation and rhizosphere colonization, which may be essential in promoting plant growth. B. velezensis containing agricultural waste could stimulate indigenous Pseudomonas and promote plant growth by enhancing biofilm formation and rhizosphere colonization.

“…However, a large proportion of bacteria and fungi associated with banana remain unidentified and their functional potential unknown (Kaushal, Swennen, et al, 2020a; Köberl et al, 2015). Traditional culture‐dependent approaches and advanced culture‐independent approaches, such as next‐generation sequencing and DNA metabarcoding (Table 1), have been used to profile microbial assemblages associated with banana under different management practices (Kaushal, Swennen, et al, 2020a; Köberl et al, 2015; Yuan, Hong, et al, 2021a; Yuan, Wang, et al, 2021b).…”

“…Soil management practices, such as the application of organic amendments, intercropping or crop rotation, have been shown to modulate the structure and composition of banana‐associated microbial communities (Yuan, Hong, et al, 2021a; Yuan, Wang, et al, 2021b) that can be harnessed for effective disease suppression (Tables 2 and 3). Generally, bulk soil harbours diverse bacterial and fungal communities, which progressively decline in the rhizosphere and roots of the banana plant, suggesting that bulk soil serves as the pool of microbial communities (Kaushal, Mahuku, et al, 2020b).…”

Banana (Musa spp.) is a giant perennial herb with a pantropical distribution (Heslop-Harrison & Schwarzacher, 2007). Bananas originated in South-east Asia following interspecific and intraspecific hybridization between two wild diploid species, Musa acuminata (AA) and M. balbisiana (BB). These two species contributed the A and B genomes, respectively, resulting in more than 1000 banana varieties comprising diploids (AA, AB, BB), triploids (AAA, AAB, ABB) and tetraploids (ABBB) (Heslop-Harrison & Schwarzacher, 2007). Most of the cultivated bananas are triploids, which include sweet dessert bananas such as Cavendish (AAA), Gros Michel (AAA), Apple (Silk AAB), Pome (AAB) and Pisang Awak (ABB), and cooking bananas such as Matooke bananas (Musa spp. genomic group AAA), plantains (AAB) and Bluggoe (ABB) (Heslop-Harrison & Schwarzacher, 2007).
