A scenario of bamboo’ culm elongation and development at molecular, physiological, cellular and tissue level. During the growth season, some environmental cues such as sufficient moisture, appropriate temperature, fertile soil and low light drive plant circadian rhythm, stimulate cell differentiation, division and growth, and biosynthesis of plant hormones, especially auxin and ABA, through some signaling sensor and transduction pathways. And then the cells take up energy or nutrients through glycolysis, photorespiration, glycan and energy metabolism to maintain normal metabolic activity, which promotes cell division, elongation or death, lignin and cellulose deposition, eventually leading to elongation and development of the Moso bamboo’ culm.
