Abstract:
... Copper-contaminated soils were managed with aided phytoextraction in 31 field plots at a former wood preservation site, using a single incorporation of compost (OM) and dolomitic limestone (DL) followed by a crop rotation with tobacco and sunflower. Six amended plots, with increasing total soil Cu, and one unamended plot were selected together with a control uncontaminated plot. The mobility and p ...

... Branched broomrape (Orobanche ramosa L.) is a chlorophyll-lacking, root parasitic plant that infects many crops and wild species (2). Plants are densely hairy with minute, glandular hairs, particularly on flowers and upper stems. Stems are erect, often branched just above the ground, and brown to straw yellow. Leaves are sparse, triangular, dark brown or purple, and arranged alternately mainly nea ...

Abstract:
... Most adult Lepidoptera feed on nectar, whereas caterpillars consume mainly structural tissue such as leaves, stems, flowers, and/or fruits. This may result in behavioral trade-offs in which search time for high-quality oviposition sites suitable for larval food is restricted by adult foraging needs. Here we report on the preference for and performance on flowering and nonflowering host plants of t ...

Abstract:
... T-phylloplanin proteins secreted to aerial surfaces of tobacco (Nicotiana tabacum) by short procumbent trichomes inhibit spore germination and blue mold disease caused by the oomycete pathogen Peronospora tabacina. Many other plants were found to contain water-washed leaf surface proteins (phylloplanins), but the functions and properties of these are not known. Here we extend earlier evidence for ...

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 ...

In roots containing a GUS reporter fusion to the Hahsp17.7G4 pr ...
