Web27 feb. 2014 · This hemibiotroph infects only cacao pods and has an extended biotrophic phase lasting up to sixty days, culminating in plant necrosis and sporulation of the fungus without the formation of a basidiocarp. Results. M. roreri genome. Of the 17,920 predicted open reading frames (OFRs), 13,760 were validated by RNA-Seq. WebPenetrating a host leaf surface composed of cutin covered with wax is the first challenge to plant pathogens. Infection requires intricate sensing and signalling in both plant and pathogen (Knogge, 1998; van Kan, 2006). The pathogen must choose whether, when and where to germinate, develop an infection structure and/or produce enzymes and ...
