► We investigated ozone effect on rice yield in relation to spikelet formation. ► Ozone-induced small panicle is the main reason of yield loss in rice. ► Ozone inhibits spikelet differentiation and promotes spikelet degeneration. This study investigated the impact of elevated ozone concentration ([O...
