Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Optimization of fermentation medium for Iturin A by improved artificial neural network approach

, 2015
为提高伊枯草菌素A(Iturin A)的产量,选择发酵培养基中对Iturin A合成有影响的5个组分作为自变量、以Iturin A产量为响应值,设计5因素10水平的均匀设计试验。以均匀设计试验数据为基础,分别建立二次多项式模型和一种改进型人工神经网络模型来优化发酵培养基,最后通过比较两种模型的优劣选择改进型人工神经网络模型优化培养基组分。结果表明,相比于二次多项式模型,基于相同试验设计的改进型人工神经网路模型有更好的拟合精度和泛化能力,使用人工神经网络模型优化后的培养基发酵48 h后,Iturin ...

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

Advanced Science, Volume 13, Issue 47, 24 August 2026.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

Bioprospecting Indoor Bacteria Producing Bioactive Metabolites

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
The indoor environments served as easily accessible habitats for bacteria producing mitochondrial toxins and ionophores, effects exhibited by known antiparasitic drugs and effects useful in mitochondrial research. This study describes the bacterial species and genera producing toxic peptide antibiotics and identifies some of their biological targets in

Influence of the Culture Medium on the Production of Iturin A by Bacillus subtilis [PDF]

Microbiology, 1987
The production of iturin A by Bacillus subtilis was studied with respect to the composition of the culture medium. Increasing phosphate concentrations did not modify the antibiotic yield. Fructose, sucrose and mannitol were better carbon sources than glucose for antibiotic production.

Microbial Community Shifts and Plant Performance Improvements Driven by Bacillus firmus in Pampa Agroecosystems

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
The study shows that Bacillus firmus‐based bionematicides modulate soil microbiota and enhance soybean growth in the Pampa biome. Effects vary by location and time, with increased beneficial bacteria, reduced fungi, and decreased root nematode infestation. Overall, B.

Kinetic analysis on precursors for iturin A production from Bacillus amyloliquefaciens BPD1

, 2019
In this study, the precursor effect for iturin A production was quantitatively analyzed. A strain identified as Bacillus amyloliquefaciens BPD1 (Ba-BPD1) was selected due to its ability to produce iturin A.
