Rice (Oryza sativa L.), a monocot model plant, is an important cereal crop in the world. The flowering time, inflorescence and floral organ morphological structure have significant influence on rice yield and quality. The research on the structure and development of floral organs is helpful to improve the grain yield and rice quality. The development and morphogenesis of floral organ is a vital process from vegetative growth to reproductive growth in rice. More and more biological researches focus on its developmental pattern and molecular mechanism. The glumes of rice spikelets are unique organs and consisted of lemmas, paleae, sterile lemmas and rudimentary glumes. The molecular mechanisms of the formation and origin of glumes keep poor understanding. Recently, further study of the glumes help to not only understand the rice spikelet and floral organ development, but also facilitate understanding of the regulatory network involved in rice spikelet and floral organ development. In this paper, we focus on the rice glume development and review the ABCDE model of floral organ specialization.
