متن کاملMovement of Soil-Applied Imidacloprid and Thiamethoxam into Nectar and Pollen of Squash (Cucurbita pepo)
There has been recent interest in the threat to bees posed by the use of systemic insecticides. One concern is that systemic insecticides may translocate from the soil into pollen and nectar of plants, where they would be ingested by pollinators. This paper reports on the movement of two such systemic neonicotinoid insecticides, imidacloprid and thiamethoxam, into the pollen and nectar of flowe...
متن کاملl-Ornithine:2-Oxoacid Aminotransferase from Squash (Cucurbita pepo, L.) Cotyledons: Purification and Properties.
ORNITHINE: 2-oxoacid aminotransferase (EC 2.6.1.13) has been purified over 400-fold with a total recovery of 14% from acetone powders of cotyledons of germinating squash (Cucurbita pepo, L.) seedlings. The pH optimum of the transamination between l-ornithine and alpha-ketoglutarate is 8 and the Michaelis constants are 4.7 mm and 6.3 mm, respectively. The enzyme has a molecular weight of 48,000 ...
متن کاملDistribution of a - Galactosidase in Cucurbita pepo
The distribution of a-galactosidase (a-D-galactoside galactohydrolase IEC 3.2.1.221) in Cucurbita pepo has been determined in an attempt to assess its involvement in hydrolysis of transport sugars of the raffinose oligosaccharide series (la-1-6-galactopyranosyllj sucrose). Extracts prepared from leaves and petioles at different stages of development, roots, flowers, dry and germinating seeds, a...
متن کاملMetabolic Requirement of Cucurbita pepo for Boron.
Lateral roots of intact summer squash seedlings (Cucurbita pepo L.) were used to quantify the effects of boron deficiency on DNA synthesis, protein synthesis, and respiration. The temporal relationship between changes in these metabolic activities and the cessation of root elongation caused by boron deprivation was determined. Transferring 5-day-old squash seedlings to a hydroponic culture medi...
