Alternative splicing of flowering time gene FT is associated with halving of time to flowering in coconut

Alternative splicing and the control of flowering time.

The fca mutant of Arabidopsis is one of numerous late-flowering mutants in the autonomous, or constitutive, floral promotion pathway (Koornneef et al., 1991, 1998). The autonomous pathway acts independently of the photoperiod pathway and intersects with the vernalization response pathway in the control of flowering. The FCA gene encodes a novel protein that contains RNA binding domains and a pu...

Identification of AFLP markers associated with flowering time and ornamental traits in Chrysanthemum

 Flowering period and longevity play important roles in determining the quality of commercial flowers. Marker-trait associations for eight flowering and 12 ornamental traits have been studied using a GLM and MLM analysis with a set of 2099 AFLP polymorphic markers in Chrysanthemum. The GLM model identified 453 markers for phenotypic traits whereas the MLM association analysis model revealed a t...

BRR2a Affects Flowering Time via FLC Splicing

Several pathways control time to flowering in Arabidopsis thaliana through transcriptional and posttranscriptional gene regulation. In recent years, mRNA processing has gained interest as a critical regulator of flowering time control in plants. However, the molecular mechanisms linking RNA splicing to flowering time are not well understood. In a screen for Arabidopsis early flowering mutants w...

A naturally occurring splicing site mutation in the Brassica rapa FLC1 gene is associated with variation in flowering time

FLOWERING LOCUS C (FLC), encoding a MADS-domain transcription factor in Arabidopsis, is a repressor of flowering involved in the vernalization pathway. This provides a good reference for Brassica species. Genomes of Brassica species contain several FLC homologues and several of these colocalize with flowering-time QTL. Here the analysis of sequence variation of BrFLC1 in Brassica rapa and its a...
