Plants undergo a series of developmental transitions during their life cycle.After seed germination,plants pass through two distinct phases:the vegetative phase in which leaves are produced and the reproductive phase in which flowering occurs.Based on the reproductive competence and morphological changes,the vegetative phase can be further divided into juvenile and adult phases.Here,we demonstrate that the difference between juvenile and adult phase of Nicotiana tabacum is characterized by the changes in leaf size,leaf shape as well as the number of leaf epidermal hairs (trichomes).We further show that miR 156,an age-regulated microRNA,regulates juvenile-to-adult phase transition in N.tabacum.Overexpression of miR156 results in delayed juvenile-to-adult transition and flowering.Together,our results support an evolutionarily conserved role of miR 156 in plant developmental transitions.
