PROTEÍNAS ANTIFÚNGICAS CONTRA P. INFESTANS EN LOS ESPACIOS INTERCELULARES DE HOJAS DE TOMATE (Lycopersicon esculentum cerasiforme) POSIBLES DEFENSINAS DE PLANTAS
Keywords:
espacios intercelulares, hojas, tomate, proteínas PR (relacionadas con patogenicidad), Defensinas de plantas, actividad antifúngica (es)Downloads
después de inoculación con el patógeno dichas proteínas se acumularon sistémicamente en la planta. Las proteínas identificadas
mostraron características de Defensinas de plantas, una nueva familia de proteínas con bajo peso molecular, carga positiva a pH fisiológico y actividad antifúngica evaluada in vitro contra P. infestans.
Los análisis electroforéticos en geles de poliacrilamida con SDS-Tricina en condiciones reductoras y no reductoras, sugirieron que están asociadas en trímeros y tetrámeros y poseen pesos moleculares de 5,2 kDa.
