Abstract:
... Kochia [Bassia scoparia (L.) A.J. Scott] is a problematic summer-annual tumbleweed that infests cropped and noncropped areas in the Great Plains of North America. Efficient seed dispersal, prolific seed production, and abiotic stress tolerance facilitate invasiveness of kochia, while both resource-limiting and non-resource-limiting interference aid in rapid colonization of disturbed areas. Resista ...

Abstract:
... In nonagricultural systems, the relationship between intrinsic water‐use efficiency (WUEᵢ) and leaf nitrogen (Nₐᵣₑₐ) is known to be stronger for legumes than for nonlegumes. We tested whether these relationships are retained for major agricultural legumes and nonlegumes. We compared the response to N nutrition of WUEᵢ (and its component parts, photosynthesis (Aₛₐₜ) and stomatal conductance (gₛ)) f ...

Abstract:
... Water supply frequently limits crop yield in semiarid cropping systems; water deficits can restrict yields in drought-affected subhumid regions. In semiarid wheat (Triticum aestivum L.)-based cropping systems, replacing an uncropped fallow period with a crop can increase precipitation use efficiency but reduce wheat productivity. Our objective was to analyze crop sequence and environmental effects ...

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:
... Ubiquitin is a ubiquitous protein involved in targeting proteins for degradation. Maize pollen was previously reported (Callis and Bedinger 1994) to show extremely low levels of ubiquitin monomer, and developmental significance was attributed to this surprising feature of maize pollen. However, we had previously shown (Muschietti et al. 1994) that tomato pollen had high levels of ubiquitin monomer ...
