  abstract = {{W}e tested the ability of root-adhering soils ({RAS}) from eight rice cultivars to attract a bacterivorous nematode ({A}crobeloides sp.) living in a poor-nutrient soil in {M}adagascar. {W}e showed that the ability of rice to attract bacterivorous nematodes in its rhizosphere is variable among cultivars. {FOFIFA} 172 was the cultivar with the highest attraction value, the lowest root biomass ({RB}) and the highest {RAS}:{RB} ratio and {RAS} respiration. {I}n contrast, nematodes exhibited strong repellent response to {W}880 {RAS}. {A}lso, nematode attractancy was not related to rice resistance against pests (blast rice disease and {S}triga asiatica) neither to cultivar ability to grow at specific altitude. {O}ur results suggest a trade-off in carbon allocation between plant biomass and root exudation driving nematode attractancy and raise questions about the impact of plant breeding on cultivar ability to interact with soil mutualists such as bacterivorous nematodes. {F}urther investigations are required into (i) variation in root exudate quantity and composition among the eight cultivars and (ii) the response of rice cultivars to bacterivorous nematode inoculation.},
