  abstract = {{M}eloidogyne graminicola is a major plant-parasitic nematode affecting rice cultivation in {A}sia. {R}esistance to this nematode was found in the {A}frican rice genotypes {O}ryza glaberrima and {O}. longistaminata; however, due to interspecific hybrid sterility, the introgression of resistance genes in the widely consumed {O}. sativa varieties remains challenging. {R}ecently, resistance was found in {O}. sativa and, here, we report for the first time the histological and genetic characterization of the resistance to {M}. graminicola in {Z}honghua 11, an {O}. sativa variety. {B}right-light microscopy and fluorescence observations of the root tissue of this variety revealed that the root cells surrounding the nematode displayed a hypersensitivity-like reaction with necrotic cells at early stages of infection when nematodes are migrating in the root's mesoderm. {A}n accumulation of presumably phenolic compounds in the nematodes' neighboring root cells was also observed. {I}n addition, at a later stage of infection, not only were few feeding sites observed but also the giant cells were underdeveloped, underlining an incompatible interaction. {F}urthermore, we generated a hybrid {O}. sativa population by crossing {Z}honghua 11 with the susceptible {O}. sativa variety {IR}64 in order to describe the genetic background of this resistance. {O}ur data suggested that the resistance to {M}. graminicola infection was qualitative rather than quantitative and, therefore, major resistance genes must be involved in this infection process. {T}he full characterization of the defense mechanism and the preliminary study of the genetic inheritance of novel sources of resistance to {M}eloidogyne spp. in rice constitute a major step toward their use in crop breeding.},
