Transmission electron micrographs of cross-sections through anthers of rice plants at the vacuolization microspore stages sprayed with SA under control and heat stress. a-h, anthers under control pretreatment with different SA concentrations; i-p, anthers under heat stress pretreatment with different SA concentrations. Bar = 2μm. P, pollen grain; T, tapetum; M, middle layer; E, endothecium
