What's a GeneRIF?

a cross-repressive interaction of GNC and GNL on the one side and SOC1 on the other in the control of flowering time, greening, and cold tolerance
Title: Cross-repressive interactions between SOC1 and the GATAs GNC and GNL/CGA1 in the control of greening, cold tolerance, and flowering time in Arabidopsis.
Constitutive Cga1 overexpression increases both chloroplast biogenesis and starch production but also results in delayed senescence and reduced grain filling. Cga1 regulates chloroplast development in higher plants.
Title: Rice cytokinin GATA transcription Factor1 regulates chloroplast development and plant architecture.
Data indicate that CARBON-METABOLISM INVOLVED (GNC) and GNC-LIKE (GNL)/CYTOKININ-RESPONSIVE GATA FACTOR1 (CGA1) expression is repressed by AUXIN RESPONSE FACTO ARF2 and ARF7.
Title: Convergence of auxin and gibberellin signaling on the regulation of the GATA transcription factors GNC and GNL in Arabidopsis thaliana.
GNC and CGA1 regulate chlorophyll production, and positively regulate chloroplast growth in the hypocotyl.
Title: Functional characterization of the GATA transcription factors GNC and CGA1 reveals their key role in chloroplast development, growth, and division in Arabidopsis.
CGA1 encodes a GATA factor, whose expression is rapidly induced by both the light and cytokinin signals in Arabidopsis thaliana.[CGA1]
