Abstract:
... The E1 promoter fragment (-249 to -203) is one of three auxin-response elements (AuxREs) in the soybean (Glycine max L.) GH3 promoter (Z.-B. Liu, T. Ulmasov, X. Shi, G. Hagen, T.J. Guilfoyle [1994] Plant Cell 6: 645-657). Results presented here further characterize and delimit the AuxRE within the E1 fragment. The E1 fragment functioned as an AuxRE in transgenic tobacco (Nicotiana tabacum L.) plan ...

Abstract:
... 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 ...
