Fig 1. Time-course of Colletotrichum kahawae (isolate Que2) infection in hypocotyls of resistant (Catimor 88) and susceptible (Caturra) coffee varieties.

3hpi and 6hpi–beginning of conidia germination and appressoria differentiation, respectively; 12hpi– 42% of melanized appressoria; 24hpi–almost 100% of melanized appressoria; 48hpi—fungal penetration and biotrophic growth; 72hpi–switch to necrotrophy (susceptible variety) and restriction of fungal growth (resistant variety). Times after inoculation (bold) were selected to collect samples for gene expression studies by qPCR.
