- ... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

- ... An endogenous inhibitor of the in vitro binding of the phytotropin N-1-naphthylphthalamic acid to microsomal membranes was detected in extracts prepared from etiolated pea (Pisum sativum L.) epicotyls. Following extensive purification, the inhibitor was identified as linoleic acid. Authentic linoleic acid inhibited N-1-naphthylphthalamic acid binding noncompetitively in a dose-dependent manner, ex ...
