Technical Abstract: Rice physiology occurs in physical space through chemical reactions constrained by anatomy and morphology, and is guided by genetics. Genes encode proteins that are subsequently processed to produce enzymes that direct and govern the biochemical processes involved in the physiology of the plant. Rice and other grass crops possess a large number of genes in common, and because it has the smallest genome of all commercial crops, rice often serves as a useful model system for research and improvement of other crops. Rice is physiologically distinct from most other plants in several respects, including its ability to adapt to flooded conditions and its ability to selectively absorb and utilize silica from soils. In this chapter we review numerous aspects of rice physiology including life cycle, phytohormone regulation of plant growth, seedling development, vegetative development including photosynthesis and aerenchyma cell formation and function, reproductive development and grain filling, and mineral nutrition, plant abnormalities, and associated stress relating to nitrogen nutrition, salt toxicity, zinc deficiency, iron toxicity (akagare), straighthead abnormalities, and oxidative stress.
