Plant growth and development involves with the integration of many environmental and endogenous signals that determine plant form together with the intrinsic genetic program. Fundamental to this process are several growth regulators which we collectively called the plant hormones or phytohormones [1]. For many years,
phytohormones have been considered to fall into five classes: auxins; gibberellins (GAs); cytokinins; abscisic acid (ABA) and ethylene. More recently, a variety of additional classes such as jasmonic acid (JA) and brassinosteriods (BRs) have been added [1]. Each of these classes acts at low concentrations to regulate almost every aspect of plant growth and development to some degree [2]. Phytohormones not only act to control many aspects of plant growth and development but also response to the environment stresses [3].Their signaling pathways can be effectively controlled by modulation of positive and negative regulators during plant growth and development [4]. Among these, small RNA was recently found to be a new growth regulator involved in plant hormone signaling.
