Effect of wheat germ isolectins on development of cowpea weevil
1991
Huesing, J.E. | Murdock, L.L. | Shade, R.E.
Wheat germ agglutinin (WGA) isolated from hexaploid wheat is made up of six isolectin dimeric forms. In order to determine if the previously observed biological activity of WGA against the cowpea weevil was due preferentially to particular isolectins, we isolated each of the three isolectin homodimers and bioassayed them in an artificial seed bioassay. We show that each of the isolectins is equally detrimental to the growth and development of the cowpea weevil. Hence, any of the three genes for WGA isolectins could, in principle, be transferred into cowpea to confer bruchid resistance.
