Endophytes, microorganisms inhabiting internal plant tissues, play a pivotal role in growth and disease resistance. Moreover, previous studies have established that Musa plants derive protective functions from their microbiome. Notably, one of the crop wild relatives banana, Calcutta 4 variety, exhibits resistance to various phytopathogens such as Pseudocercospora fijiensis (P. fijiensis), while Williams commercial cultivar (cv.) is highly susceptible. Therefore, this study aims primarily characterize compare endophytic microbiota composition banana when grown sympatrically. Alongside, differences microbiome between sections (shoot or roots), phases (in vitro greenhouse) fitness factors addition growth-promoting bacteria Bacillus subtilis EA-CB0575 (T2 treatment) infection by P. (T3 were examined. Both culture-dependent -independent techniques used evaluate these assess culturability endophytes under varying conditions. Microbial cultures resulted 331 isolates distributed across 54 genera all treatments evaluated, whereas 16 S sequencing produced 9510 ASVs assigned 1456 genera. Alpha beta diversity exhibited significant based on section, with an increase phylogenetic observed pathogen (T3) compared control (T1). Additionally, four differentially abundant associated nitrogen metabolism identified T3 seven showed differential abundance comparing varieties. When methods compared, it was found represented 3.7 % detected culture-independent methods, accounting for 12-41 total data depending treatment. These results are crucial proposing management strategies derived enhance resilience susceptible varieties against affecting development. they help decipher pathogenic effects advance understanding how domestication influences endosphere.

Abstract Root exudates are composed of primary and secondary organic compounds that function as signalling molecules play important roles in plant-environment interactions. The quantity composition root vary depending on the species, genotype, environmental conditions, including presence identity neighbouring plants. Although cover crops commonly used agricultural practices for their ecosystem services, such weed suppression, pathogen control, soil structure improvement, studies limited. Our study provides first characterization black oat interacting with neighbours, redroot pigweed blackgrass, well neighbours same oat. We investigated how these interactions influence exudation patterns. Furthermore, we impact exposure to exudate treatments affects traits weeds. upregulated detected response plants primarily belonged oxygen superclass, most which identified amino acids carbohydrates. In pigweed, a general increase was observed, sugar sulphates being upregulated. had varying effects among While significant decreases observed traits, an blackgrass. Similarly, more pronounced were compared blackgrass upon application. This insights into dynamic nature plant

The aim of this study was to evaluate the effects winter cover crops (CCs) on soybean agronomic performance and their implications for different physiological groups rhizosphere microorganisms in two sustainable production systems. techniques rye, peas, oats are well known, but suitability as CCs (organic low-input) needs be examined. After years trials, yields among tested (peas (P + O) rye (R)) were statistically significant only P O. yield succession O 3.0 t ha−1, whereas R, it 2.7 control plot, 2.6 ha−1. average grain protein content range 40 41% dry matter (DM), while oil ranged from 20 22% DM. Protein primarily depends selected variety is confirmed through that, studied system, we can obtain adequate nutritional quality. results indicate an increase abundance total bacteria, ammonifiers, free N2-fixing bacteria rhizosphere, depending CCs, differences between According study, (CCs), including peas (R), included crop rotation soybean. answer agro-biodiversity empowerment less diverse cropping systems, along with other benefits that provide at level rotation. In addition, almost all aspects organic ahead low input. Low input system if there no opportunities certification producers who aware advantages also represent a transitional path towards regenerative agriculture or production.
