WebFeb 1, 2006 · Researchers have used light studies to reveal that the flowering time control protein (FCA) is an ABA receptor that plays a vital role in the metabolism of RNA to control flowering time in ... WebSep 27, 2024 · In this study, we demonstrate that calcium-dependent protein kinase 32 (CPK32) regulates flowering time by affecting the alternative polyadenylation of FLOWERING CONTROL LOCUS A (FCA) and altering the transcription of FLOWERING LOCUS C (FLC), a central repressor of flowering time.
The RNA-binding protein FCA is an abscisic acid receptor
Following a BLAST search in the Solanaceae Genomics Network, we identified two GAMYB-like genes, SlGAMYB1 (Solyc01g009070) and SlMYB33 (Solyc06g073640), in tomato. Since the SlGAMYB1 gene has been reported previously20, we focused on SlMYB33 in this study. SlMYB33 contains three exons and two … See more To address the possible functions of SlMYB33, we first evaluated its expression profiles in various tissues of tomato (Micro-Tom) through qRT-PCR. SlMYB33 is mainly expressed in stamens and pistils, in which its transcript … See more To identify the potential genes and molecular pathways involved in SlMYB33-regulated tomato flowering, transcriptome analysis was performed in shoot apices (30-day-old, not … See more To determine the biological function of SlMYB33, we attempted to inhibit its expression in Micro-Tom plants using gene-silencing technology. An RNA interference (RNAi) … See more To evaluate whether SlMYB33 could affect anther and pollen development similarly to a typical GAMYB homolog7,12,16,17, the pollen phenotypes were analyzed in the SlMYB33-RNAi lines. … See more WebJan 19, 2006 · FCA, an RNA binding protein that regulates flowering time, binds abscisic acid with high affinity.

WebMay 1, 2002 · The predicted FCA protein contains two copies of an RNA binding domain, the RNP (also referred to as RNA recognition motif or consensus sequence RNA-binding domain), ... Genetic analysis in Arabidopsis has enabled the isolation of genes that control flowering time, and the identification of interacting pathways that promote flowering in ... WebJun 1, 2003 · FCA contains a WW protein interaction domain that is essential for FCA function. We have identified FY as a protein partner for this domain. FY belongs to a highly conserved group of eukaryotic proteins represented in Saccharomyces cerevisiae by the RNA 3' end-processing factor, Pfs2p. FY regulates RNA 3' end processing in Arabidopsis … WebJan 14, 2010 · Abstract. The spen family protein FPA is required for flowering time control and has been implicated in RNA silencing. The mechanism by which FPA carries out these functions is unknown. We report the identification of an activity for FPA in controlling mRNA 3' end formation. We show that FPA functions redundantly with FCA, … fluff monster furniture
