  abstract = {{R}ising temperatures and extreme heat events threaten rice production. {H}alf of the global population relies on rice for basic nutrition, and therefore developing heat-tolerant rice is essential. {D}uring vegetative development, reduced photosynthetic rates can limit growth and the capacity to store soluble carbohydrates. {T}he photosystem {II} ({PSII}) complex is a particularly heat-labile component of photosynthesis. {W}e have developed a high-throughput chlorophyll fluorescence-based screen for photosynthetic heat tolerance capable of screening hundreds of plants daily. {T}hrough measuring the response of maximum {PSII} efficiency to increasing temperature, this platform generates data for modelling the {PSII}-temperature relationship in large populations in a small amount of time. {C}oefficients from these models (photosynthetic heat tolerance traits) demonstrated high heritabilities across {A}frican ({O}ryza glaberrima) and {A}sian ({O}ryza sativa, {B}engal {A}ssam {A}us {P}anel) rice diversity sets, highlighting valuable genetic variation accessible for breeding. {G}enome-wide association studies were performed across both species for these traits, representing the first documented attempt to characterize the genetic basis of photosynthetic heat tolerance in any species to date. {A} total of 133 candidate genes were highlighted. {T}hese were significantly enriched with genes whose predicted roles suggested influence on {PSII} activity and the response to stress. {W}e discuss the most promising candidates for improving photosynthetic heat tolerance in rice. {A} high-throughput platform for screening heat tolerance using chlorophyll fluorescence was developed and utilized to identify candidate genes underlying photosynthetic heat tolerance in {A}frican and {A}sian rice via {GWAS}.},
