- ... Microprojectile- or Agrobacterium-mediated DNA delivery into calluses initiated from immature embryos has proven to be effective in transforming wheat. Yet, obtaining a large number of high quality immature embryos throughout the year is a laborious and delicate process. To circumvent these limitations, we propose an alternative technique applying the particle bombardment technology to calluses de ...

- ... 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 ...
