Abstract: Abstract Young roots of wheat, barley, and sorghum, as well as methyl jasmonate pretreated rice seedlings, undergo an unprecedented allene oxide synthase pathway targeted to previously unknown oxylipins 1–3. These Favorskii‐type products, (4Z)‐2‐pentyl‐4‐tridecene‐1,13‐dioic acid (1),… read more here.
