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 ...

Cowpea Trypsin Inhibitor and Resistance to Cowpea Weevil (Coleoptera: Bruchidae) in Cowpea Variety ‘TVu 2027’

Environmental Entomology, 1994
Seeds of cowpea, Vigna unguiculata (L.) Walp, line ‘TVu 2027’ are moderately resistant to the cowpea weevil, Callosobruchus maculatus (F.). C. maculatus larvae exhibit higher mortality and take longer to develop in ‘TVu 2027’ than in more susceptible seeds. Claims have been made (Gatehouse, A.M.R., J. A. Gatehouse, P. Dobie, A. M.

Dissipation behavior, residue distribution and dietary risk assessment of cyromazine, acetamiprid and their mixture in cowpea and cowpea field soil.

The Journal of the Science of Food and Agriculture, 2020
BACKGROUND Cyromazine and acetamiprid are widely applied as pesticides in agriculture, causing increasing concerns about their residues in crops. In this study, cyromazine, acetamiprid and their mixture were applied to cowpea to investigate their ...

Complete genome sequences of cowpea polerovirus 1 and cowpea polerovirus 2 infecting cowpea plants in Burkina Faso

Archives of Virology, 2017
The full-length genome sequences of two novel poleroviruses found infecting cowpea plants, cowpea polerovirus 1 (CPPV1) and cowpea polerovirus 2 (CPPV2), were determined using overlapping RT-PCR and RACE-PCR. Whereas the 5845-nt CPPV1 genome was most similar to chickpea chlorotic stunt virus (73% identity), the 5945-nt CPPV2 genome was most similar to ...

Effect of a Synthetic Lysolecithin on the Multiplication of Cowpea Mosaic Virus in Cowpea Protoplasts

Biochemie und Physiologie der Pflanzen, 1989
Summary 2-0-hexadecyl-glycero-3-posphocholine (GPC) is a synthetic lysolipid with antiphytoviral activity. GPC applied at concentrations higher than 0.01 mM caused visual damage of cowpea protoplasts. While pretreatment of protoplasts with 0.6 M mannitol containing potassium citrate buffer and GPC does not cause significant changes in the infection ...

Factors influencing the infection of cowpea protoplasts by cowpea mosaic virus RNA

Virology, 1976
Abstract Protoplasts were isolated from primary leaves of cowpeas ( Vigna sinensis ) by a slight modification of the procedure reported (Beier and Bruening, 1975) . They were inoculated with cowpea mosaic virus RNA under various conditions. The highest yield of virus from the infected protoplasts was achieved when viral RNA was incubated in 0.45 M
