The Past, Present, and Future of Vegetative Phase Change

Transitioning to the Next Phase: The Role of Sugar Signaling throughout the Plant Life Cycle

“…The relationship between heteroblasty and attainment of floral competence differs between species, and some species may even flower before vegetative changes become apparent (Poethig, 2010). Different signaling pathways may therefore exist (Matsoukas, 2014b;Hyun et al, 2017).…”

“…The juvenile-to-adult phase transition comprises major morphological changes during shoot development (heteroblasty or vegetative phase change) as well as developmental changes that result in the competence to flower under inductive conditions (Poethig, 2010). In some woody species (e.g.…”

Modularity and intra-floral integration in metameric organisms: plants are more than the sum of their parts

“…Such regular patterns of intra-individual variation among vegetative metamers are well-known features of ontogeny, and this phenomenon is termed heteroblasty [4]. Heteroblasty is clearly under genetic control and, for model organisms, is associated with gradients in the activities of at least two microRNAs [5,6].…”

The control of developmental phase transitions in plants

“…During the juvenile-to-adult phase transition (see Glossary, Box 1), plants thus acquire reproductive competence. Simultaneously, changes in multiple traits, such as leaf size and shape, internode length and trichome distribution, result in the appearance of both early (juvenile) and mature (adult) shoots on the same plant, a condition known as heteroblasty (see Glossary, Box 1) (Goebel, 1889;Poethig, 1990;Poethig, 2010).…”
