Scientists at the Salk Institute have identified a plant enzyme denoted SOBER1 that plants use to seemingly lower their resistance to infection. Future study on the gene may lead to ways to boost natural immunity or contain infections that would otherwise decimate entire agricultural crops and biofuel resources.<\/p>\n<p>Additional experiments involved several model plant species (Arabidopsis, oilseed rape, and tobacco) and evaluated the structure and function of SOBER1 and an immune protein known as AvrBst. The ultimate goal of this work is to understand how bacterial resistance works in plants. The information gained may help identify new methods of improving agricultural and biofuel crop resistance to harmful bacterial infections.<\/p>\n<p><strong>References<br \/>\n<\/strong><a href=\"https:\/\/www.nature.com\/articles\/s41467-017-02347-w\" target=\"_blank\" rel=\"noopener\">A hydrophobic anchor mechanism defines a deacetylase family that suppresses host response against YopJ effectors,<\/a>\u00a0Nature Communications, 2017; 8 (1) DOI: 10.1038\/s41467-017-02347-w,\u00a0Marco B\u00fcrger, Bj\u00f6rn C.
