  abstract = {{T}he root-knot nematode ({RKN}) {M}eloidogyne incognita is one of the most damaging parasites of coffee ({C}offea arabica) plantations. {T}he aim of this study was to compare defense-related genes transcription patterns in resistant and susceptible coffee genotypes after nematode challenge. {R}oot tips of the {C}. arabica '{UFV}' (resistant) and '{CV}' (susceptible) genotypes were collected at 4, 5 and 6 days post-infection ({DPI}) with {M}. incognita. {T}he expression patterns of 88 genes related to plant immunity were assessed by q{RT}-{PCR} in infected and control coffee roots. {I}n susceptible plants, most of the genes were suppressed from 5 {DPI}, when nematode feeding sites are induced. {I}n resistant plants, gene expression was mostly activated at 6 {DPI}, when a hypersensitive response-like phenotype is detectable. {R}esistance was associated with over-expression of genes coding for {M}iraculin (defense), {RGLG}1 (protein degradation), {SENA} (senescence-associated cell death), {NLR} (immunity signaling), {C}a{WRK}11 (transcription factor), and {OBP} (cell wall modification). {I}nterestingly, some genes presented contrasting profiles during the compatible ({S}) and incompatible ({R}) interactions: {C}4{H}, {NLR}, {TUBBY} (transcription factor), and {CAF}sy (alkaloid metabolism-related). {A} {NRP} ({N}-rich protein)-based response could to be associated with the coffee response to the nematode. {D}ata obtained here improve our knowledge about the coffee immune responses to {M}. incognita and provide novel genes for plant resistance breeding.},
