Effects of GNA and other mannose binding lectins on development and fecundity of the peach-potato aphid Myzus persicae

N. Sauvion ; Y. Rahbe ; W. Peumans ; E. Vandamme ; J. Gatehouse ; A. Gatehouse | 1996

Three mannose-binding lectins were assayed in artificial diets for their toxic and growth-inhibitory effects on nymphal development of the peach-potato aphid Myzus persicae. The snowdrop (Galanthus nivalis) lectin GNA was the most toxic, with an[...]

Expression of the insecticidal lectin from snowdrop (Galanthus nivalis agglutinin; GNA) in transgenic wheat plants: effects on predation by the grain aphid Sitobion avenae

E. Stoger ; S. Williams ; P. Christou ; R. Down ; J. Gatehouse | 1999

Transgenic wheat plants containing the gene encoding snowdrop lectin (Galanthus nivalis agglutinin; GNA) under the control of constitutive and phloem-specific promoters were generated through the particle bombardment method. Thirty-two independe[...]

Transgenic potato plants with enhanced resistance to the peach-potato aphid Myzus persicae

A. Gatehouse ; R. Down ; K. Powell ; N. Sauvion ; Y. Rahbe ; C. Newell ; A. Merryweather ; W. Hamilton ; J. Gatehouse | 1996

Potato plants (Solanum tuberosum) cv. Desiree were transformed with the genes encoding the proteins bean chitinase (BCH), snowdrop lectin (GNA) and wheat a-amylase inhibitor (WAI) under the control of the constitutive Ca MV 35 S promoter. Transg[...]
