Los\u00a0Candidatus<\/em>\u00a0Phytoplasma son procariotes sin pared celular pertenecientes a la clase Mollicutes (mycoplasmas), que invaden el floema y se transmiten por chicharritas vectoras. Los fitoplasmas no pueden ser cultivados\u00a0in vitro<\/em>,\u00a0y\u00a0 se caracterizan por poseer un genoma peque\u00f1o (0.53 – 1.35 Mb), con bajo %GC (21-28%) (Kube et al. 2008<\/a>;\u00a0Marcone et al. 1999<\/a>).\u00a0Causan amarillamientos, achaparramientos, escobas de bruja y otras alteraciones del crecimiento.<\/p>\n

El agente causal de\u00a0la\u00a0Proliferaci\u00f3n del manzano se encuentra en los tubos cribosos\u00a0del floema. El fitoplasma es altamente pleom\u00f3rfico, de aproximadamente 200-800 nm de di\u00e1metro, limitado por una membrana citopl\u00e1smica trilaminar pero sin una pared celular r\u00edgida (Seem\u00fcller, 1990).<\/p>\n
