  abstract = {{J}asmonate dually impacts osmotic and ionic components of salt stress in rice. {J}asmonate is required for abscisic acid-mediated water deprivation responses, but inhibits {N}a(+)retention in roots, promoting leaf damage. {P}lant responses to salt exposure involve large reconfigurations of hormonal pathways that orchestrate physiological changes towards tolerance. {J}asmonate ({JA}) hormones are essential to withstand biotic and abiotic assaults, but their roles in salt tolerance remain unclear. {H}ere we describe the dynamics of {JA} metabolism and signaling in root and leaf tissue of rice, a plant species that is highly exposed and sensitive to salt. {R}oots activate the {JA} pathway in an early pulse, while the second leaf displays a biphasic {JA} response with peaks at 1 h and 3 d post-exposure. {B}ased on higher salt tolerance of a rice {JA}-deficient mutant (aoc), we examined, through kinetic transcriptome and physiological analysis, the salt-triggered processes that are under {JA} control. {P}rofound genotype-differential features emerged that could underlie the observed phenotypes. {A}bscisic acid ({ABA}) content and {ABA}-dependent water deprivation responses were impaired in aoc shoots. {M}oreover, aoc accumulated more {N}a+ in roots, and less in leaves, with reduced ion translocation correlating with root derepression of the {HAK}4 {N}a+ transporter gene. {D}istinct reactive oxygen species scavengers were also stronger in aoc leaves, along with reduced senescence and chlorophyll catabolism markers. {C}ollectively, our results identify contrasted contributions of {JA} signaling to different sectors of the salt stress response in rice.},
