Previously, we described the AtGRF [Arabidopsis thaliana growth-regulating factor (GRF)] gene family, which encodes putative transcription factors that play a regulatory role in growth and development of leaves and cotyledons. We demonstrate here that the C-terminal region of GRF proteins has transactivation activity. In search of partner proteins for GRF1, we identified another gene family, GRF-interacting factor (GIF), which comprises three members. Sequence and molecular analysis showed that… Expand
The transcription factor AtGRF5 and the transcription coactivator AN3 regulate cell proliferation in leaf primordia of Arabidopsis thaliana.
TLDR
Describing two genes from Arabidopsis thaliana suggest that AN3 and AtGRF5 act together and are required for the development of appropriate leaf size and shape through the promotion and/or maintenance of cell proliferation activity in leaf primordia. Expand
GIP1 may act as a coactivator that enhances transcriptional activity of LBD18 in Arabidopsis.
TLDR
Reverse-transcription-polymerase chain reaction analysis showed overlapping expression of GIP1 and LBD18 in various tissues of Arabidopsis such as roots, aerial parts, and rosette leaves, indicating that GIP 1 may act as a transcriptional coactivator of LBD 18. Expand
Overexpression of the maize GRF10, an endogenous truncated growth-regulating factor protein, leads to reduction in leaf size and plant height.
TLDR
It is proposed that ZmGRF10 aids in fine-tuning the homeostasis of the GRF-GIF complex in the regulation of cell proliferation, which is important in controlling plant growth and development. Expand
Isolation and characterization of genes encoding GRF transcription factors and GIF transcriptional coactivators in Maize (Zea mays L.)
TLDR
It is postulated that these four genes which expressed preferentially in immature ear tissues in maize might play important roles in the growth and development of ears and might contribute to improving corn yields. Expand
The Arabidopsis GRF-INTERACTING FACTOR Gene Family Performs an Overlapping Function in Determining Organ Size as Well as Multiple Developmental Properties1[C][W][OA]
TLDR
It is demonstrated that the other members of the GIF gene family, GIF2 and GIF3, are also required for cell proliferation and lateral organ growth, as gif1, gif2, and gif3 mutations cause a synergistic reduction in cell numbers, leading to small lateral organs. Expand
Post-transcriptional control of GRF transcription factors by microRNA miR396 and GIF co-activator affects leaf size and longevity.
TLDR
It is found that, in addition to the leaf size, the GRF system also affects the organ longevity and the functions of GRFs in leaf growth and senescence can be uncoupled, demonstrating that the miR396-GRF-GIF network impinges on different stages of leaf development. Expand
GROWTH-REGULATING FACTOR4 ofArabidopsis thaliana is required for development of leaves, cotyledons, and shoot apical meristem
TLDR
It is suggested that GRF4 is required for both leaf cell proliferation and the embryonic development of cotyledons and the shoot apical meristem in Arabidopsis thaliana. Expand
Regulation of plant growth and development by the GROWTH-REGULATING FACTOR and GRF-INTERACTING FACTOR duo.
TLDR
Molecular and biological functions of the two transcription regulator families, GRF and GIF, which have only recently been recognized are reviewed, revealing the presence of a complex regulatory circuit in regulation of plant growth and development by the GRF-GIF duo. Expand
Biological roles and an evolutionary sketch of the GRF-GIF transcriptional complex in plants
TLDR
The current review highlights recent advances in the understanding of how the GRF-GIF-miR396 module regulates plant growth and development and revise the previous view on the evolutionary origin of theGRF gene family. Expand
Interaction between the GROWTH-REGULATING FACTOR and KNOTTED1-LIKE HOMEOBOX Families of Transcription Factors1[W]
Members of the GRF family are conserved transcriptional regulators in both monocot and dicot plants. KNOTTED1-LIKE HOMEOBOX (KNOX) genes are important regulators of meristem function, and a complexExpand

The AtGRF family of putative transcription factors is involved in leaf and cotyledon growth in Arabidopsis.
TLDR
Results indicate that AtGRF proteins play a role in the regulation of cell expansion in leaf and cotyledon tissues in Arabidopsis thaliana. Expand

TLDR
The results indicate that Os-GRF1 belongs to a novel class of plant proteins and may play a regulatory role in GA-induced stem elongation and was expressed in Arabidopsis. Expand
Whole genome analysis of the OsGRF gene family encoding plant-specific putative transcription activators in rice (Oryza sativa L.).
TLDR
Results indicate that OsGRF1 acts as a transcriptional activator and postulate that it may be involved in regulating vegetative growth in rice. Expand
The ROTUNDIFOLIA3 gene of Arabidopsis thaliana encodes a new member of the cytochrome P-450 family that is required for the regulated polar elongation of leaf cells.
TLDR
The results imply that the ROT3 protein is a member of a new class of cytochrome P-450 encoding putative steroid hydroxylases, which is required for the regulated polar elongation of cells in leaves of Arabidopsis. Expand
The ANGUSTIFOLIA gene of Arabidopsis, a plant CtBP gene, regulates leaf‐cell expansion, the arrangement of cortical microtubules in leaf cells and expression of a gene involved in cell‐wall formation
TLDR
It is found that the abnormal arrangement of cortical microtubules in an leaf cells appeared to account entirely for the abnormal shape of the cells, and it was suggested that the AN gene might regulate the polarity of cell growth by controlling the arrangement of cortex MTs. Expand
Overexpression of a novel small peptide ROTUNDIFOLIA4 decreases cell proliferation and alters leaf shape in Arabidopsis thaliana.
TLDR
Phylogenetic analysis indicates that ROT4 defines a novel seed plant-specific family of small peptides with 22 members in Arabidopsis, ROT FOUR LIKE 1-22 (RTFL1-22). Expand
Two independent and polarized processes of cell elongation regulate leaf blade expansion in Arabidopsis thaliana (L.) Heynh.
TLDR
It is proposed that leaf expansion in Arabidopsis involves at least two independent developmental processes: width development and length development, with the ANGUSTIFOLIA and ROTUNDIFOLia3 genes playing different polarity-specific roles in cell elongation. Expand
The cell morphogenesis gene ANGUSTIFOLIA encodes a CtBP/BARS‐like protein and is involved in the control of the microtubule cytoskeleton
TLDR
It is shown that the AN gene encodes a C‐terminal binding proteins/brefeldin A ADP‐ribosylated substrates related protein, which suggests that CtBP/BARS‐like protein function in plants is directly associated with the microtubule cytoskeleton. Expand
SYT Associates with Human SNF/SWI Complexes and the C-terminal Region of Its Fusion Partner SSX1 Targets Histones*
TLDR
SYT-SSX interferes with the function of either the SNF/SWI complexes or another SYT-interacting co-activator, p300, by changing their targeted localization or by directly inhibiting their chromatin remodeling activities. Expand
Functional domains of the SYT and SYT-SSX synovial sarcoma translocation proteins and co-localization with the SNF protein BRM in the nucleus.
TLDR
It is demonstrated that the human homologue of the SNF2/Brahama protein BRM co-localizes with SYT and SYT-SSX in nuclear speckles, and also interacts withSYT andSYT- SSX proteins in vitro, which may provide an explanation of how the SYT protein activates gene transcription. Expand
