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 ...

Summer fallow is commonly used to stabilize winter wheat (Triticum aestivum L.) production in the Central Great Plains, but summer fallow results in soil degradation, limits farm productivity and profitability, and stores soil water inefficiently. The objectives of this study were to quantify the production and economic consequences of replacing summer fallow with spring-planted crops on the subse ...

Abstract:
... The plasma membrane is most likely the major target for sensing of aluminium (Al), leading to inhibition of plant root-growth. As a result of high external Al, alterations in plasma membrane composition may be expected in order to maintain its properties. As sphingolipids are characteristic components of this membrane, their involvement in membrane adjustment to increased Al concentrations was inv ...
