- ... 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 ...

- ... Five different varieties of Brassica napus (Cyclone, Dunkled, Oscar, Rainbow and KS75) were tested for their regeneration response. Cyclone showed a very high frequency of regeneration (92%). The use of silver nitrate was a pre-requisite for efficient shoot regeneration. Hypocotyls were selected as the starting material for transformation experiments on the basis of high transient GUS expression. ...
