Potato lectin plants

Down, R.E., Gatehouse, A.M.R., Hamilton, W.D.O., and Gatehouse, J.A., Snowdrop lectin inhibits development and decreases fecundity of the glasshouse potato aphid (Aulacorthum solani) when administered in vivo and via transgenic plants both in laboratory and glasshouse trials, J. Insect Physiol., 42, 1035-1045, 1996. 

Although seeds are the common source of lectin activity, there are reports (some contradictory) of agglutinins occurring in leaves, stems, and roots.77,94 For example, black-locust (Robinia pseudoaccacia) lectin160 was isolated from its bark, potato (Solanum tuberosum) lectin161 from its tubers, and poke-weed (Phytolacca americanum) mitogen162 from its roots. A new class of plant cell-wall and membrane-bound lectins ( /3-lectins ) has been described.116,163,164 A treatise collected several schemes for the purification of lectins.165,1658... 

The extensins are highly insoluble components of cell walls of terrestrial plants and are considered to be important in the plastic extension of the typical cell wall of the land plants (Lamport, 1970, 1973). However, some of the related arabinoproteins are found elsewhere in the cell, and one of the best studied is the readily soluble lectin of the potato, Solanum tuberosum (Allen and Neuberger, 1973), which has a high content of carbohydrate.
