TLDR
The events that occur in the meristem of A. thaliana during the floral transition are reviewed and compared with the understanding of flowering in perennial systems.Abstract:
In plants the switch from vegetative growth to flowering involves a major transition in the development of the shoot apex. This transition can occur once, in annual species, or repeatedly, in perennial plants. In annuals, flowering is associated with senescence and death of the whole plant, whereas perennials flower in consecutive years and maintain vegetative development after flowering. The perennial life strategy depends on differential behavior of meristems on a single plant so that some remain in the vegetative state while others undergo the floral transition. A. thaliana provides a powerful model system for understanding the mechanisms of flowering in annuals. Here we review the events that occur in the meristem of A. thaliana during the floral transition and compare these with our understanding of flowering in perennial systems.read more

TL;DR: It is found that sufficient amount of the LDMAR transcript is required for normal pollen development of plants grown under long-day conditions, and this finding has important implications for understanding molecular mechanisms of photoperiod regulation of many biological processes and also for developing male sterile germplasms for hybrid crop breeding.

TL;DR: In this article, the authors report that functionally diverged paralogs FLOWERING LOCUS T1 (FT1) and FT2 (FT2) coordinate the repeated cycles of vegetative and reproductive growth in woody perennial poplar (Populus spp.).

Flowering time regulation in crops—what did we learn from Arabidopsis?
TL;DR: This work summarizes recent discoveries on FTi regulators in crop species emphasizing crop-specific genes lacking homologs in Arabidopsis thaliana and highlights pleiotropic effects on agronomically important characters, impact on adaptation to new geographical/climate conditions and future perspectives for crop improvement.

LEAFY Target Genes Reveal Floral Regulatory Logic, cis Motifs, and a Link to Biotic Stimulus Response

TL;DR: This study reveals that LFY directs an elaborate regulatory network in control of floral homeotic gene expression, and supports a key role for LFY in the coordination of reproductive stage development and disease response programs in plants that may ensure optimal allocation of plant resources for reproductive fitness.

Vernalization – a cold-induced epigenetic switch
TL;DR: The principles derived from vernalization are likely to be widely relevant to epigenetic reprogramming in many organisms, and have recently been elaborated on through the use of mathematical modelling.

TL;DR: It is concluded that FT protein acts as a long-distance signal that induces Arabidopsis flowering, and evidence that FT does not activate an intermediate messenger in leaves is provided.

FLOWERING LOCUS C Encodes a Novel MADS Domain Protein That Acts as a Repressor of Flowering
TL;DR: This study reports that flc null mutations result in early flowering, demonstrating that the role of active FLC alleles is to repress flowering, and proposes that the level of FLC activity acts through a rheostat-like mechanism to control flowering time in Arabidopsis and that modulation of F LC expression is a component of the vernalization response.
