  abstract = {{T}he response of a susceptible coffee cultivar ({C}aturra) to infection by the root-knot nematode {M}eloidogyne exigua was compared histologically with that of cv. {I}apar 59 possessing the recently identified {M}ex-1 resistance gene. {T}he reproductive behaviour of the nematode was also compared in the two cultivars. {P}enetration and development in resistant plants were reduced in comparison with susceptible plants. {S}everal cell features, including dark-stained cytoplasm and altered organelle structure, were observed in the resistant cultivar, indicating a hypersensitive-like ({HR}) response of the infested host cells. {F}eatures of giant cells were sometimes found beside necrotic-like areas, but the corresponding feeding sites were frequently associated with nematodes displaying abnormal shape. {S}ix weeks after inoculation, root systems of cv. {C}aturra contained significantly more nematodes than those of cv. {I}apar 59 (mean values 1574 and 41, respectively). {T}he susceptible cultivar presented a minimum of 11 galls per plant, compared with only one or two galls per plant in the resistant cultivar. {T}he findings are discussed in the context of plant-pathogen interactions.},
