Regulation of floral patterning by flowering time genes.
Floral patterning in Arabidopsis requires activation of floral homeotic genes by the floral meristem identity gene, LEAFY (LFY). Here we show that precise activation of expression of class B and C homeotic genes in floral meristems is regulated by three flowering time genes, SHORT VEGETATIVE PHASE (SVP), SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1), and AGAMOUS-LIKE 24 (AGL24), through dir...
متن کاملSugars, 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 کاملFlowering on time: genes that regulate the floral transition. Workshop on the molecular basis of flowering time control.
Successful sexual reproduction in plants depends on the recognition of favourable environmental conditions and the integration of that information with endogenous developmental cues. Flowering in higher plants involves the transition of a vegetative meristem, producing leaves and stems, into a floral meristem, producing flowers. Most of our understanding of the regulation of the floral transiti...
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 کاملDirected network discovery with dynamic network modelling.
Cognitive tasks recruit multiple brain regions. Understanding how these regions influence each other (the network structure) is an important step to characterize the neural basis of cognitive processes. Often, limited evidence is available to restrict the range of hypotheses a priori, and techniques that sift efficiently through a large number of possible network structures are needed (network ...
