Response of cowpea lines to inoculation with four seed transmitted viruses of cowpea.

Serodiagnosis of Cowpea (Vigna Unguiculata) Viruses in Gilan Province, Iran

Response of Cowpea Breeding Lines and Cultivars to Meloidogyne incognita and M. arenaria.

Twenty-four cowpea breeding lines and four cultivars were tested for resistance to Meloidogyne incognita in the greenhouse. Gall and egg mass ratings indicated a range of responses from susceptible to highly resistant. Five breeding lines - VS84-2, VS84-8, VS84-12, VS84-14, and VS84-22 - and the cultivar Erectset had gall and egg mass ratings comparable to the M. incognita-resistant cultivar Mi...

Responses of Soybean and Cowpea Root Membranes to Inoculation with Azospirillum brasilense

Inoculation with Azospirillum brasilense Cd of two leguminous species, soybean (Glycine max) and cowpea (Vigna unguiculata), demonstrated that: (1) A. brasilense significantly increased proton efflux from their roots; (2) inoculation reduced plant membrane potential (in soybean), (3) inoculation changed the phospholipid quantity in plant membranes of calli (in cowpea), and (4) a low molecular w...

Purification of a Ltp from Cowpea Seed Exudate

Plants exude a variety of substances through their surface especially of roots and germinating seeds. Some of these released compounds seem to have an inhibitory action against certain pathogens. Lipid transfer proteins (LTPs) are 9 kDa cysteine-rich cationic peptides and are thought to play a role in the protection of plants against microbial infections. The aim of this work was to isolate and...
