Gene : AGL20 A. thaliana

Gene ID  ? AT2G45660
Brief Description  AGAMOUS-like 20  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? AGAMOUS-like 20 (AGL20); FUNCTIONS IN: sequence-specific DNA binding transcription factor activity; INVOLVED IN: flower development, response to cold, positive regulation of flower development, maintenance of inflorescence meristem identity; LOCATED IN: nucleus; EXPRESSED IN: 22 plant structures; EXPRESSED DURING: 12 growth stages; CONTAINS InterPro DOMAIN/s: Transcription factor, MADS-box (InterPro:IPR002100), Transcription factor, K-box (InterPro:IPR002487); BEST Arabidopsis thaliana protein match is: AGAMOUS-like 42 (TAIR:AT5G62165.3).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Controls flowering and is required for CO to promote flowering. It acts downstream of FT. Overexpression of (SOC1) AGL20 suppresses not only the late flowering of plants that have functional FRI and FLC alleles but also the delayed phase transitions during the vegetative stages of development. AGL20/SOC1 acts with AGL24 to promote flowering and inflorescence meristem identity.AGL20 upregulates expression of AGL24 in response to GA.  Source: TAIR, Jun 30, 2015.

SOC1 gene. MADS box proteins are thought to bind their DNA targets as dimers or higher-order multimers 16623882
once AP1 is activated during the floral transition, it acts partly as a master repressor in floral meristems by directly suppressing the expression of flowering time genes SVP, AGL24 and SOC1, preventing continuation of the shoot developmental program 17428825
during floral transition, a positive-feedback loop conferred by direct transcriptional regulation between AGL24 and SOC1 at the shoot apex integrates flowering signals 18339670
Interaction with AGL24 relocates SOC1 to the nucleus, where SOC1 regulates leafy expression by binding to the LFY promoter. 18466303
EARLY FLOWERING9 (ELF9), an Arabidopsis thaliana RNA binding protein, directly targets the SOC1 transcript and reduces SOC1 mRNA levels. 19376936
SOC1 is able to bind directly to regulatory regions of class B and C homeotic genes. 19656343
Results demonstrate the presence of feedback loop that delays flowering through the increase of FLC when a cold spell is transient but suppresses the cold response when floral induction occurs through the repression of cold-inducible genes by SOC1. 19825833
Flowering was promoted by induction of FT and SOC1 expression with blue light in Arabidopsis, whereas GpFTs and GpSOC1 expression was low with blue light induction in G. paniculata. 21431295
SOC1 directly controls the expression of AGL42, AGL71 and AGL72 to balance the expression level of these SOC1-like genes. 21609362
SOC1-SPL module serves as a molecular link that integrates photoperiod and gibberellic acid signals to promote flowering in Arabidopsis. 21988498
Findings show that feedback regulatory loops mediated by SOC1 and SVP are essential components of the gene regulatory networks that underpin the integration of flowering signals during floral transition. 22268548
Our studies provide insight into the role of MPF2-like genes in phase transition by interacting with SOC1 and MAF1 genes, thereby also pointing to their significance as potential candidates for modifying flowering in crop plants in the future. 22539207
SOC1 constitutes a major hub in the regulatory networks underlying floral timing and flower development and that these networks are composed of many positive and negative autoregulatory and feedback loops. 22791302
Flowering is controlled by AGL24 partly independently of SOC1 and FUL. 22902690
