Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, Volume 13, Issue 38, 9 July 2026.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Florigens and antiflorigens: a molecular genetic understanding [PDF]

Essays in Biochemistry, 2015
Florigens, the leaf-derived signals that initiate flowering, have been described as ‘mysterious’, ‘elusive’ and the ‘Holy Grail’ of plant biology. They are synthesized in response to appropriate photoperiods and move through the phloem tissue. It has been proposed that their composition is complex.

Ectopic over-expression of two apple Flowering Locus T homologues, MdFT1 and MdFT2, reduces juvenile phase in Arabidopsis

Biologia Plantarum, 2010
To get insight into mechanism by which apple tree (Malus domestica Borkh.) regulates flowering, two apple flowering locus T (FT) homologues, MdFT1 and MdFT2, were isolated from the leaf cDNAs of cultivar Gala.

RICE CENTRORADIALIS 1, a TFL1-like Gene, Responses to Drought Stress and Regulates Rice Flowering Transition

Rice, 2020
Background The initiation of flowering transition in rice (Oryza sativa) is a complex process regulated by genes and environment. In particular, drought can interfere with flowering; therefore, many plants hasten this process to shorten their life cycle ...

Triple florigenic signaling in rice promotes stem elongation via transcriptional de‐repression

The Plant Journal, Volume 127, Issue 2, 2026.
Significance Statement Rice florigenic proteins Hd3a, RFT1, and FT‐L1 coordinate reproductive transition with stem elongation through repression of PINE1 expression, independently of floral MADS box proteins, relieving repression of internode growth. PINE1 represses growth by transcriptionally repressing target genes by interacting with TOPLESS‐related

Flowering time: From photoperiodism to florigen [PDF]

Current Biology, 1998
An Arabidopsis blue-light receptor, Cry2, has been found to play a critical role in the photoperiodic control of flowering time; and genes have been identified that may control the production of a transmissible flower-inducing signal, which may turn out to be the long-elusive putative flowering hormone 'florigen'.

FLOWERING LOCUS T Genes MtFTb1 and MtFTb2 Act Redundantly to Promote Flowering Under Long Days in Medicago truncatula

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Flowering time is a crucial agronomic trait affecting yield and plant performance in different climates and photoperiods. While the molecular pathways regulating photoperiodic flowering are well‐characterized in Arabidopsis and cereals, they remain poorly understood in many other groups of plants.

Florigen and the Photoperiodic Control of Flowering in Rice [PDF]

Rice, 2008
Abstract Flowering time is a key trait for geographical and seasonal adaptation of plants and is an important consideration for rice breeders. Recently identified genetic factors provide new insights into this complex trait. The list of genes involved in flowering and their functions tells us that the molecular basis of day-length measurement

Allele‐informed QTL‐seq identifies Hd18 as a minor modifier of heading date in elite rice cultivars

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Fine‐tuning heading date is critical for optimizing yield, grain quality, and local adaptation in rice (Oryza sativa L.). QTL‐seq (where QTL is quantitative trait locus), which integrates bulked segregant analysis with whole‐genome resequencing, provides a rapid and cost‐effective approach for identifying QTLs underlying complex traits ...

Natural variation of the RICE FLOWERING LOCUS T 1 contributes to flowering time divergence in rice.

PLoS ONE, 2013
In rice (Oryza sativa L.), there is a diversity in flowering time that is strictly genetically regulated. Some indica cultivars show extremely late flowering under long-day conditions, but little is known about the gene(s) involved.
