Transmission of Tobacco Mosaic Virus by Myzus persicae
It is well known that many plant viruses can be transmitted by aphids, but the highly infectious tobacco mosaic virus (TMV) seems to have no aphid vector. Only Hoggan (1934) reported a very low level of transmission which, however, has not been substantiated (Orlob, 1963; Pirone, 1969).

Overexpression of Nictaba-like lectin genes from glycine max confers tolerance towards Pseudomonas syringae infection, aphid infestation and salt stress in transgenic Arabidopsis plants [PDF]
Plants have evolved a sophisticated immune system that allows them to recognize invading pathogens by specialized receptors. Carbohydrate-binding proteins or lectins are part of this immune system and especially the lectins that reside in the ...

Determination of Resistance Levels of Myzus persicae (Sulzer) by Biochemical Methods [PDF]
Peach/potato aphid Myzus persicae (Sulzer) has developed three mechanisms of resistance: overproduction of one or two closely related carboxylesterases (E4 and FE4), production of modified acetylcholinesterase (MACE and knockdown resistance ...
