The MADS box gene, FOREVER YOUNG FLOWER, acts as a repressor controlling floral organ senescence and abscission in Arabidopsis.
TLDR
The data suggest a role for FYF in controlling floral senescence/abscission by repressing ethylene responses and regulating the expression of BOP2 and IDA in Arabidopsis. Expand
C/D class MADS box genes from two monocots, orchid (Oncidium Gower Ramsey) and lily (Lilium longiflorum), exhibit different effects on floral transition and formation in Arabidopsis thaliana.
TLDR
The similarities of the expression patterns of OMADS4/LMADS10 and OMADS2 to those of C and D class genes, respectively, indicate that their transcriptional regulation is highly evolutionarily conserved in these monocot species. Expand
Functional analysis of three lily (Lilium longiflorum) APETALA1-like MADS box genes in regulating floral transition and formation.
TLDR
The ability of lily LMADS6 and 7 to complement the Arabidopsis ap1 mutant provided further evidence to show that the conserved motifs (paleoAP1 or euAP1) in the C-terminus of the SQUA/AP1 subfamily of MADS box genes is not strictly necessary for their function. Expand
ERECTA Family Genes Regulate Auxin Transport in the Shoot Apical Meristem and Forming Leaf Primordia1[C][W][OPEN]
TLDR
It is shown that ERfs regulate auxin transport during leaf initiation and are essential for PIN1 expression in the forming midvein of future leaf primordia and in the vasculature of emerging leaves. Expand
Functional analysis reveals the possible role of the C-terminal sequences and PI motif in the function of lily (Lilium longiflorum) PISTILLATA (PI) orthologues
TLDR
The results revealed that the 29 amino acids including the PI motif in the C-terminal region of the lily PI orthologue are valuable for its function in regulating perianth organ formation. Expand
FOREVER YOUNG FLOWER Negatively Regulates Ethylene Response DNA-Binding Factors by Activating an Ethylene-Responsive Factor to Control Arabidopsis Floral Organ Senescence and Abscission1
TLDR
The results reveal that FYF regulates flower senescence/abscission by negatively regulating EDF1/2/3/4, which is the downstream gene in the ethylene response, by activating FUF1 in Arabidopsis. Expand
Regulation of Plasmodesmatal Permeability and Stomatal Patterning by the Glycosyltransferase-Like Protein KOBITO11[W][OA]
TLDR
A novel mutant of KOBITO1 is described in Arabidopsis (Arabidopsis thaliana), where the kob1-3 mutation leads to the formation of stomata clusters in the erl1 erl2 background but not in the wild type, demonstrating that cellulose biosynthesis is not a major determining factor for regulating plasmodesmatal permeability. Expand
Delay of flower senescence and abscission in Arabidopsis transformed with an FOREVER YOUNG FLOWER homolog from Oncidium orchid
TLDR
The evidence is the similar delay of flower senescence and abscission observed in transgenic Arabidopsis ectopically expressing OnFYF, an FYF homolog from the Oncidium orchid, a monocot, which suggested that the function of FYF Homologs in regulating flower senesence andAbscission was highly conserved in both dicot and monocots plants. Expand
ERECTA family genes regulate development of cotyledons during embryogenesis
TLDR
During embryogenesis ERECTA family (ERf) receptors redundantly stimulate the growth of cotyledons by promoting cell proliferation and inhibiting premature stomata differentiation. Expand
Expression and characterization of monocot rice cytosolic CuZnSOD protein in dicot Arabidopsis
TLDR
Analysis indicates that rSODI most likely corresponds to native rice CuZnSOD that has incorporated the Cu and Zn ions required for full activity, whereas the less active rS ODII form may not have properly incorporated the necessary copper ions. Expand
