  abstract = {{I}n {A}frican rice, higher transpiration efficiency is associated with transpiration restriction that is itself controlled by root-shoot growth balance. {G}enes potentially controlling these traits were identified. {I}mproving crop water use efficiency, the amount of carbon assimilated as biomass per unit of water used by a plant, is of major importance as water for agriculture becomes scarcer. {I}n rice, the genetic bases of transpiration efficiency, the derivation of water use efficiency at the whole-plant scale, and its putative component trait transpiration restriction under high evaporative demand remain unknown. {T}hese traits were measured in 2019 in a panel of 147 {A}frican rice ({O}ryza glaberrima) genotypes known to be potential sources of tolerance genes to biotic and abiotic stresses. {O}ur results reveal that higher transpiration efficiency is associated with transpiration restriction in {A}frican rice. {D}etailed measurements in a subset of highly contrasted genotypes in terms of biomass accumulation and transpiration confirmed these associations and suggested that root to shoot ratio played an important role in transpiration restriction. {G}enome wide association studies identified marker-trait associations for transpiration response to evaporative demand, transpiration efficiency, and its residuals, with links to genes involved in water transport and cell wall patterning. {O}ur data suggest that root-shoot partitioning is an important component of transpiration restriction that has a positive effect on transpiration efficiency in {A}frican rice. {B}oth traits are heritable and define targets for breeding rice with improved water use strategies.},
