Common mechanism of recognition and binding of the complementary molecules, carbohydrate-lectin, in the verticillium disease of Agaricus bisporus and Pleurotus ostreatus cultivated mushrooms

Se compara la interacción carbohidrato-lectina entre el glucogalactomananoaislado de las paredes celulares de Verticillium fungicola y las lectinas de los carpóforosde Agaricus bisporus o de Pleurotus ostreatus, para establecer el mecanismomolecular de la «mole seca» o verticiliosis de los cultivos comerciales de ambassetas comestibles. La interacción entre las moléculas complementarias, «moléculasdiana», parece ser debida a la galactosa terminal unida en (1-4) al esqueleto demanosa unido en (1-6) de la molécula del glucogalactomanano de V. fungicola

The carbohydrate-lectin interaction between the isolated glucogalactomannanof Verticillium fungicola cell walls, and lectins, either from Agaricus bisporus orPleurotus ostreatus fruit bodies, was compared in order to establish the molecularmechanism of the «dry bubble» or verticillium disease exhibited in the commercialcultures of both edible mushrooms. This interaction between complementarymolecules, «target molecules», appears to be due to the terminal galactose linkedat (1-4) to the (1-6) mannose bone of the V. fungicola glucogalactomannan molecule
