Animal-derived substances, such as chitosan, propolis, and antimicrobial peptides, primarily exert antibacterial effects through membrane disruption and immune system stimulation. Microbial-derived natural products contribute to synergistic disease suppression by modulating host immunity and interfering with the pathogen\u2019s quorum sensing mechanisms. Evidence indicates that these natural products possess multi-target antimicrobial properties, offering a rich repository of candidate molecules, such as baicalein, lignans, and carvacrol, for the development of eco-friendly antibacterial agents. Future investigations should focus on detailed characterization of these bioactive compounds and their specific disease targets, optimization of extraction methodologies to improve stability and bioavailability, and comprehensive assessment of environmental safety to advance the industrial implementation of sustainable biocontrol strategies\n                  <\/jats:p>","DOI":"10.3389\/fpls.2026.1754522","type":"journal-article","created":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T06:57:51Z","timestamp":1772607471000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Natural products for biocontrol of Pseudomonas syringae: mechanisms and applications"],"prefix":"10.3389","volume":"17","author":[{"given":"Xiaosen","family":"Han","sequence":"first","affiliation":[{"name":"School of Pharmacy, Hunan University of Chinese Medicine","place":["Changsha, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zihan","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Hunan University of Chinese Medicine","place":["Changsha, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sai","family":"Jiang","sequence":"additional","affiliation":[{"name":"Institute of Innovative Traditional Chinese Medications, Hunan Academy of Chinese Medicine","place":["Changsha, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Hunan University of Chinese Medicine","place":["Changsha, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Hunan University of Chinese Medicine","place":["Changsha, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"B1","first-page":"119575","article-title":"Essential structural features of sulfated polysaccharides required for plant immunity induction","volume":"291","author":"Ale","year":"2022","journal-title":"Carbohydr Polym."},{"key":"B2","doi-asserted-by":"publisher","first-page":"76","DOI":"10.1016\/j.phytochem.2016.01.001","article-title":"Expression of antimicrobial peptides under control of a camalexin-biosynthetic promoter confers enhanced resistance against Pseudomonas syringae","volume":"122","author":"Alexandra","year":"2016","journal-title":"Phytochemistry"},{"key":"B3","unstructured":"Normative Instruction No. 43, of 18 August 2022.
