High-temperature-tolerant rice has distinctive anthers
Anticipated global warming may induce floret sterility in rice even in temperate regions. Matsui and Omasa (pp. 683-687) examine the relationship between morphological characteristics of anthers and tolerance of the floret to high temperatures. Compared with susceptible cultivars, tolerant cultivars have fewer cell layers separating the anther locule from the lacuna formed in the septum.
