A gene encoding a preprohydroxyproline-rich systemin, SnpreproHypSys, was identified from the leaves of black nightshade (Solanum nigrum), which is a member of a small gene family of at least three genes that have orthologs in tobacco (Nicotiana tabacum; NtpreproHypSys), tomato (Solanum lycopersicum; SlpreproHypSys), petunia (Petunia hybrida; PhpreproHypSys), potato (Solanum tuberosum; Phprepro...

Plot-scale field studies were conducted to evaluate the efficacy of steam for the control of cropland weeds in comparison with common herbicides. Weed densities, biomass, or emergence after treatment were measured. Steam (3,200 kg/ha, energy dosage equivalent to 890 kJ/m2, speed of 0.8 m/s) and glyphosate (560 g ai/ha) gave similar control (. 90%) of seedling common lambsquarters and seedling r...

In a search for an analogue of AAL-toxin with high phytotoxicity and low mammalian toxicity, aminopentols [(AP1), hexacetyl AP1 and N-acetyl AP1], and nine analogues (1-9), were tested for toxicity to duckweed (Lemna pausicostata), susceptible tomato (asc/asc) leaf discs, black nightshade leaf discs and mammalian cell lines, including dog kidney (MDCK), rat liver hepatoma (H4TG) and mouse fibro...

potato tuberworm, phthorimaea operculella zeller (lepidoptera; gelechiidae) is a worldwide pest of solanaceous crops. larvae feed inside galleries in foliage, stems and tubers making chemical control unsuccessful, so other control methods should be applied. in recent years many plants have received genes that encode toxic proteins as a strategy to resist insect pests. in this study, optimal ph ...

Leafy vegetables play a crucial role in the human diet providing numerous nutrients and health benefiting compounds. like collard (Brassica oleracea var. acephala) black nightshade (Solanum nigrum l.) are commonly consumed leafy Kenya. However, their high perishability short shelf life (usually 1-2 days at ambient temperature) limits utilization resulting significant postharvest losses. This st...

The presence of volunteer potato Solanum tuberosum L., cutleaf nightshade, S. triflorum N., and hairy nightshade, S. physalifolium Rusby (Solanales: Solanaceae), throughout potato crop rotations can diminish the effectiveness of crop rotations designed to control disease and pest problems associated with growing potatoes. In greenhouse bioassays, larvae of the Colorado potato beetle, Leptinotar...

Numerous plant species are considered weeds in agronomic cropping systems. Weeds have many attributes undesirable to crop producers, not the least being the ability to reduce crop yields through competition for resources such as sunlight, water, nutrients, and space. Weeds also may harbor insects and provide a host for certain plant pathogens. Some weed species, such as wild garlic and eastern ...
