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 ...

Abstract:
... Isolated plant microspores, when stressed and cultured in vitro, can be diverted from their normal gametophytic pathway towards sporophytic development, with the formation of haploid embryos and ultimately doubled-haploid plants. This process is called androgenesis or microspore embryogenesis, and is widely used in plant breeding programmes to generate homozygous lines for breeding purposes. Proto ...

Subject:
Brassica napus; Nicotiana tabacum; Secale cereale; Trifolium incarnatum; Triticum aestivum; Vicia villosa; aboveground biomass; biomass production; canola; conservation practices; cover crop termination; cover crops; crop rotation; crop-weed competition; growers; herbicides; mulches; plant density; rain; reduced tillage; rye; tobacco; weed control; weeds; wheat
Abstract:
... Weed management in tobacco (Nicotiana tabacum L.) is accomplished primarily with soilresidual herbicides, cultivation, and hand removal. Management practices that reduce weed emergence, like reduced tillage and cover crop mulches, may improve weed management efficacy. Depending on cover-cropping goals, growers face trade-offs in species selection and management priorities—producing weed-suppressiv ...
