Biocontrol mechanisms of Bacillus: Improving the efficiency of green agriculture

Microbial Biotechnology, Год журнала: 2023, Номер 16(12), С. 2250 - 2263

Опубликована: Окт. 14, 2023

Abstract Species of the genus Bacillus have been widely used for biocontrol plant diseases in demand sustainable agricultural development. New mechanisms underlying activity revealed with development microbiome and microbe‐plant interaction research. In this review, we first briefly introduce typical mechanisms, such as production antimicrobial compounds, competition niches/nutrients, induction systemic resistance. Then, discussed detail new pathogen quorum sensing interference reshaping soil microbiota. The “cry help” mechanism was also introduced, which plants can release specific signals under attack to recruit root colonization against invasion. Finally, two emerging strategies enhancing efficacy agents, including construction synthetic microbial consortia application rhizosphere‐derived prebiotics, were proposed.

The prospect of antimicrobial peptides from Bacillus species with biological control potential against insect pests and diseases of economic importance in agriculture, forestry and fruit tree production

Biotechnology & Biotechnological Equipment, Год журнала: 2024, Номер 38(1)

Опубликована: Янв. 31, 2024

Plant diseases and insect pests cause tremendous losses in agriculture, forestry fruit tree production worldwide. The continuous application of chemical pesticides the control is increasingly becoming undesirable due to associated health risks, environmental pollution pesticide resistance. Biological strategies are generally safer more sustainable alternatives plant disease pest management. Bacillus species have been widely studied commercialized as biocontrol agents, their ability produce a wide range versatile antimicrobial lipopeptides, polyketides, insecticidal toxins elicitation for induced systemic resistance (ISR). This review focuses on prospects peptides from sp. ISR against economic importance production. summarizes reports including bacterial volatile compounds various phytopathogens mechanisms involved antimicrobial/insecticidal activity defence responses. study will help researchers identify gaps future research eco-friendly management pests.

Identification and combinatorial engineering of indole-3-acetic acid synthetic pathways in Paenibacillus polymyxa

Biotechnology for Biofuels and Bioproducts, Год журнала: 2022, Номер 15(1)

Опубликована: Авг. 11, 2022

Paenibacillus polymyxa is a typical plant growth-promoting rhizobacterium (PGPR), and synthesis of indole-3-acetic acid (IAA) one the reasons for its capacity. The synthetic pathways IAA in P. must be identified modified.P. SC2 spontaneous mutant SC2-M1 could promote growth by directly secreting IAA. Through metabonomic genomic analysis, genes patA, ilvB3, fusE native IPyA pathway strain were predicted. A novel strong promoter P04420 was rationally selected, synthetically analyzed, then evaluated on ability to express genes. Co-expression three genes, fusE, increased yield 60% SC2-M1. Furthermore, heterogeneous gene iaam IAM two selected improve ELJP6_14505, ipdC, ELJP6_00725 entire from Enterobacter ludwigii JP6 expressed well engineered 13 31 μg/mL, which an increase 138%.The results our study help reveal enhance future application.

Additives Altered Bacterial Communities and Metabolic Profiles in Silage Hybrid Pennisetum

Frontiers in Microbiology, Год журнала: 2022, Номер 12

Опубликована: Янв. 5, 2022

This study was conducted to investigate the effects of different additives on fermentation quality, nutrient composition, bacterial communities, and metabolic profiles silage hybrid Pennisetum. The experiment using five treatments, i.e., CK, control group, MA, 1% malic acid fresh matter (FM) basis, GL, glucose FM CE, 100 U/g cellulase, BS, 106 cfu/g Bacillus subtilis, with six replicates each treatment. After a 120-day fermentation, 30 packages were opened for subsequent determination. As result, all four had positive quality composition high-throughput sequencing V3-V4 regions in 16S rRNA performed, results showed that Firmicutes Proteobacteria dominant phyla Aquabacterium genera. BS treatment resulted 129, 21, 25, 40 differential bacteria, respectively. upregulated smithii but downregulated Lactobacillus rossiae. Metabolic determined by UHPLC-Q/TOF-MS technology metabolites caused 47, 13, 18, These played antioxidant, antibacterial, anti-inflammatory functions involved pathways, such as citrate cycle, carbon fixation photosynthetic organisms, glyoxylate dicarboxylate metabolism. In conclusion, promoted altering communities profiles. provided potential biomarkers improvement quality.

Surfactin secreted by Bacillus amyloliquefaciens Ba01 is required to combat Streptomyces scabies causing potato common scab

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Ноя. 1, 2022

Potato common scab, which is mainly caused by the bacterium Streptomyces scabies , occurs in key potato growing regions worldwide. It causes necrotic or corky symptoms on tubers and decreases economic value of potato. At present, there no recommended chemical biological control for combating scab Taiwan. can only reduce occurrence cultivation control, but efficacy limited. Previously we found that Bacillus amyloliquefaciens Ba01 could pot assay field. The potential anti- S. mechanism was associated with surfactin secretion, further molecular dissection not conducted. Thus, this study aimed to determine whether main compound active against knocking out srf gene cluster Ba01. cloning plasmid pRY1 transformed electroporation in-frame deletion. Two independent Δ mutants were obtained confirmed specific primers mass spectrometry. swarming ability inhibition significantly decreased ( P <0.001) mutants. be restored addition surfactin. Furthermore, formed wrinkled biofilm MSgg liquid medium, while abnormally. α-amylase, protease phosphate-solubilizing decreased, inhibit growth sporulation tuber slices. In conclusion, B. responsible secretion .
