Selenate and selenite affect photosynthetic pigments and ROS scavenging through distinct mechanisms in cowpea (Vigna unguiculata (L.) walp) plants.

Ecotoxicology and Environmental Safety, 2020
Selenium (Se) is a beneficial element to higher plants. Application of Se at low concentrations enhances the antioxidant metabolism reducing the reactive oxygen species (ROS) generated by plant membrane cells.

Inheritance of resistance to the cowpea aphid in cowpea

Theoretical and Applied Genetics, 1987
Inheritance of resistance to cowpea aphid, Aphis craccivora Koch, in three resistant cultivars of cowpea, Vigna unguiculata (L.) Walp, was studied. The parents, F1 and F2 population were grown in an insect-proof screenhouse. Each 3-day-old seedling was infested with 10 apterous adult aphids. Seedling reaction was recorded when the susceptible check was

The ultrastructural appearance of cowpea mosaic virus in cowpea

Journal of Ultrastructure Research, 1975
Cowpea mosaic virions (CPMV) were present in large numbers in cowpea tissue, both in dispersed and crystalline aggregates. Virion aggregates were found after buffered glutaraldehyde or chromate fixation at pH 7.2. Five to 10 min in 5% glutaraldehyde was sufficient for good fixation and yielded sections of greater electron-density than prolonged ...

Infection of cowpea mesophyll protoplasts with cowpea mosaic virus

Virology, 1975
Mesophyll protoplasts were isolated from the primary leaves of cowpeas by a one-step procedure using a mixture of Macerozyme and Cellulase. The protoplasts were inoculated with cowpea mosaic virus and virus multiplication was shown to occur by measuring the virus infectivity at various times after inoculation.

Drought priming improved water status, photosynthesis and water productivity of cowpea during post-anthesis drought stress

, 2020
Drought occurring at the reproductive stage is the most critical phase affecting cowpea production. It remains unclear whether drought priming at the early growth stage can be employed to alleviate drought stress during the post-anthesis drought period ...

Protein fractions, in vitro protein digestibility and amino acid composition of select cowpea varieties grown in Ethiopia

, 2020
Cowpea is a drought-tolerant legume consumed as a high-quality plant protein source in many parts of the world. In this study, crude protein contents, Osborne fractions, in vitro protein digestibility and amino acid composition of proteins of 5 different

Integrated use of seed priming and biochar improves salt tolerance in cowpea

, 2020
Cowpea (Vigna unguiculata (L.) Walp.) is an important grain legume crop, mostly grown on marginal soils which hamper its productivity. Improvement of salt tolerance in cowpea is contemplated as a useful strategy to economically utilize salt-affected ...

Crystalline cowpea mosaic virus

Virology, 1980
Crystals of Cowpea mosaic virus displaying a high degree of order have been grown in two different forms. Hexagonal crystals, space group P6(1)22 or P6(5)22 with a = 450 A and c = 1038 A containing six virus particles per cell, have been grown in sodium citrate buffer at pH 4.9. Each particle has four nearest neighbors at 284 A.
