  abstract = {{B}ackground {D}ue to their sessile life style, plant survival is dependent on the ability to build up fast and highly adapted responses to environmental stresses by modulating defense response and organ growth. {T}he phytohormone jasmonate plays an essential role in regulating these plant responses to stress. {R}esults {T}o assess variation of plant growth responses and identify genetic determinants associated to {JA} treatment, we conducted a genome-wide association study ({GWAS}) using an original panel of {V}ietnamese rice accessions. {T}he phenotyping results showed a high natural genetic variability of the 155 tested rice accessions in response to {JA} for shoot and root growth. {T}he level of growth inhibition by {JA} is different according to the rice varieties tested. {W}e conducted genome-wide association study and identified 28 significant associations for root length ({RTL}), shoot length ({SHL}), root weight ({RTW}), shoot weight ({SHW}) and total weight ({TTW}) in response to {JA} treatment. {T}hree common {QTL}s were found for {RTL}, {RTW} and {SHL}. {A}mong a list of 560 candidate genes found to co-locate with the {QTL}s, a transcriptome analysis from public database for the {JA} response allows us to identify 232 regulated genes including several {JA}-responsive transcription factors known to play a role in stress response. {C}onclusion {O}ur genome-wide association study shows that common and specific genetic elements are associated with inhibition of shoot and root growth under {JA} treatment suggesting the involvement of a complex {JA}-dependent genetic control of rice growth inhibition at the whole plant level. {B}esides, numerous candidate genes associated to stress and {JA} response are co-located with the association loci, providing useful information for future studies on genetics and breeding to optimize the growth-defense trade-off in rice.},
