説明
<jats:title>Spontaneous degradation in hormone synthesis</jats:title> <jats:p> The phytohormone salicylic acid (SA) helps plants respond to biological and physical stresses. Rekhter <jats:italic>et al.</jats:italic> identified the biosynthetic pathway that produces SA in response to pathogens. A precursor, isochorismic acid, is formed in the chloroplast and then exported to the cytosol. There, enzymatically produced isochorismate-9-glutamate spontaneously decomposes to release SA plus a by-product. The results clarify key steps in the mechanisms involved in synthesizing this important regulator of plant immunity. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6452" page="498" related-article-type="in-this-issue" vol="365" xlink:href="10.1126/science.aaw1720">498</jats:related-article> </jats:p>
