Sugars, the clock and transition to flowering
Sugars do not only act as source of energy, but they also act as signals in plants. This mini review summarizes the emerging links between sucrose-mediated signaling and the cellular networks involved in flowering time control and defense. Cross-talks with gibberellin and jasmonate signaling pathways are highlighted. The circadian clock fulfills a crucial role at the heart of cellular networks ...
متن کاملThe flowering transition and florigen
What is the flowering transition? It marks the end of vegetative growth and the beginning of reproductive development in flowering plants. The physiological changes that cause it are referred to as floral induction. What is SAM? The shoot apical meristem — a group of undifferentiated progenitor cells that occupies the tip of the stem. It gives rise to both vegetative organs (leaves) and reprodu...
متن کاملTransition to Flowering and Morphogenesis of Reproductive Structures in Tomato
Flowering in tomato (Solanum lycopersicum L.) has long been investigated by plant physiologists and horticulturists aiming to increase productivity of this important fruit crop. The disruption of the sequence of events which give rise to normal development of the reproductive structures by either the manipulation of the environment, hormones or mutations has provided information useful to unrav...
متن کاملRevisiting phase transition during flowering in Arabidopsis.
Single-phase transition during flowering has been suggested by Hempel and Feldman (1994) [Planta 192: 276]. When early flowering ecotypes of Arabidopsis were microscopically observed, a long day signal simultaneously induced the acropetal (bottom to top) production of flower primordia and the basipetal (top to bottom) differentiation of paraclades (axillary flowering shoots) from the axils of p...
متن کاملDiscrete developmental roles for temperate cereal grass VERNALIZATION1/FRUITFULL-like genes in flowering competency and the transition to flowering.
Members of the grass subfamily Pooideae are characterized by their adaptation to cool temperate climates. Vernalization is the process whereby flowering is accelerated in response to a prolonged period of cold. Winter cereals are tolerant of low temperatures and flower earlier with vernalization, whereas spring cultivars are intolerant of low temperatures and flower later with vernalization. In...
