The <a href=\"https:\/\/www.nature.com\/articles\/s41477-025-02049-y\">study<\/a>\u00a0was published in Nature Plants.<\/p>\n<p>Plants, like animals, have immune systems. Part of their defense toolkit includes immune receptors, which give them the ability to detect bacteria and defend against it. One of those receptors, called FLS2, helps plants recognize flagellin \u2014 a protein in the tiny tails bacteria use to swim. But bacteria are sneaky and constantly evolving to avoid detection.<\/p>\n<p>&#8220;Bacteria are in an arms race with their plant hosts, and they can change the underlying amino acids in flagellin to evade detection,&#8221; said lead author\u00a0<a href=\"https:\/\/plantpathology.ucdavis.edu\/people\/gitta-coaker\">Gitta Coaker<\/a>, professor in the Department of Plant Pathology.<\/p>\n<p>To help plants keep up, Coaker\u2019s team turned to using natural variation coupled with artificial intelligence \u2014 specifically AlphaFold, a tool developed to predict the 3D shape of proteins and reengineered FLS2, essentially upgrading its immune system to catch more intruders.<\/p>\n<p>The team focused on receptors already known to recognize more bacteria, even if they weren\u2019t found in useful crop species. By comparing them with more narrowly focused receptors, the researchers were able to identify which amino acids to change.<\/p>\n<p>\u201cWe were able to resurrect a defeated receptor, one where the pathogen has won, and enable the plant to have a chance to resist infection in a much more targeted and precise way,\u201d Coaker said.<\/p>\n<h2><strong>Why it matters<\/strong><\/h2>\n<p>Coaker said this opens the door to developing broad-spectrum disease resistance in crops using predictive design.<\/p>\n<p>One of the researchers\u2019 targets is a major crop threat:\u00a0<em>Ralstonia solanacearum<\/em>, the cause of bacterial wilt. Some strains of the soil-borne pathogen can infect more than 200 plant species, including staple crops like tomato and potato.<\/p>\n<p>Looking ahead, the team is developing machine learning tools to predict which immune receptors are worth editing in the future. They\u2019re also trying to narrow down the number of amino acids that need to be changed.<\/p>\n<p>This approach could be used to boost the perception capability of other immune receptors using a similar strategy.<\/p>\n<p>Other authors of the study include Tianrun Li, Esteban Jarquin Bola\u00f1os, Danielle M. Stevens and Hanxu Sha of UC Davis and Daniil M. Prigozhin of Lawrence Berkeley National Laboratory.<\/p>\n<p>The research was supported by the National Institutes of Health and the United States Department of Agriculture\u2019s National Institute for Food and Agriculture.<\/p>\n<p>The post <a href=\"https:\/\/californiaagtoday.com\/how-plants-are-learning-to-spot-sneaky-bacterial-invaders\/\">How Plants are Learning to Spot Sneaky Bacterial Invaders<\/a> appeared first on <a href=\"https:\/\/californiaagtoday.com\">California Agriculture News Today<\/a>.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>With Help From AI, Researchers Upgraded Plants\u2019 Internal Alarm System to Fend Off Pathogens Scientists at the University of California, Davis, used artificial intelligence to help plants recognize a wider range of bacterial threats \u2014 which may lead to new ways to protect crops like tomatoes and potatoes from devastating diseases.
