(Submitter supplied) Leaves are flat determinate organs derived from indeterminate shoot apical meristems. The presence of a specific leaf meristem is debated, as anatomical features typical of meristems are not present in leaves. Here we demonstrate that multiple NGATHA (NGA) and CINCINNATA-class-TCP (CIN-TCP) transcription factors act redundantly to suppress activity of a leaf margin meristem in Arabidopsis thaliana, and that their absence confers persistent marginal growth of leaves, cotyledons and floral organs. more...

(Submitter supplied) Leaf development has been monitored chiefly by following anatomical markers. Analysis of transcriptome dynamics during leaf maturation revealed multiple expression patterns that rise or fall with age or that display age specific peaks. These were used to formulate a digital differentiation index (DDI), based on a set of selected markers with informative expression during leaf ontogeny. The leaf-based DDI reliably predicted the developmental state of leaf samples from diverse sources and was independent of mitotic cell division transcripts or propensity of the specific cell type. more...

(Submitter supplied) The REVOLUTA and KANADI1 transcription factors act in opposite directions to control polarity in Arabidopsis. By analyzing mRNA profiles following activation of REVOLUTA or KANADI1 proteins we identified genes regulated by both transcription factors, focusing on those regulated in opposite directions.

(Submitter supplied) AS1 and AS2 encode MYB related protein and AS2-domain containing protein, respectively and may regulate transcription. These genes are involved in the determination of axes of leaves of Arabidopsis thaliana. To know the gene regulation in the leaf development, expression profile among wild-type, as1 and as2 mutants and AS2 overexpression plants were compaired.

(Submitter supplied) Cell-cell communication is critical for stem cell maintenance. Shoot apical meristem (SAM) located at the shoot tip harbors stem cells within the central zone (CZ). Their progeny differentiate in the adjacent peripheral zone (PZ). WUSCHEL (WUS) is a homeodomain transcription factor produced in a few cells of the organizing center (OC), located beneath the CZ. It has been shown to specify stem cell fate and also activate CLAVATA3 (CLV3) expression in cells of the CZ. more...

(Submitter supplied) Plant-specific DOF-type transcription factors regulate various biological processes. Here, we characterized a silique-abundant gene AtDOF4.2 for its functions in Arabidopsis. AtDOF4.2 is localized in the nuclear region and has transcriptional activation activity in both yeast and plant protoplast assays. The Thr-Met-Asp motif in AtDOF4.2 is essential for its activation. AtDOF4.2-overexpressing plants exhibit an increased branching phenotype, and the mutation of Thr-Met-Asp motif in AtDOF4.2 significantly reduces the branching in transgenic plants. more...

(Submitter supplied) Trough a two components inducible system, we expressed ectopically in the SAM a resistant version of AP2 to the regulation of miR172 (AP2m3). The differentially expressed genes by AP2 induction allows the identification of differents groups of genes that could mediate AP2 functions in the SAM.

(Submitter supplied) The characteristic leaf shapes we see in all plants are in good part outcome of the combined action of several transcription factor networks that translate into cell division activity during the early development of the organ. We show here that wild-type leaves have distinct transcriptomic profiles in center and marginal regions. Certain transcripts are enriched in margins, including those of CINCINNATA-like TCPs, and members of the NGATHA (NGA) and STYLISH (STY) gene families. more...

(Submitter supplied) In seed plants, leaves are born on radial shoots but unlike shoots they are determinate dorsiventral organs made of flat lamina. YABBY genes are found only in seed plants and in all cases studied, are expressed primarily in lateral organs and in a polar manner. Despite their simple expression, Arabidopsis plants lacking all YABBY gene activities have a wide range of morphological defects in all lateral organs as well as the shoot apical meristem. more...

(Submitter supplied) Background: The carpel margin meristem is a vital multi-potent structure located in the medial domain of the Arabidopsis thaliana gynoecium, the female floral reproductive organ. The carpel margin meristem generates ovules that upon fertilization become seeds. The molecular mechanisms that specify this meristematic region and regulate its organogenic potential are poorly understood. Here, we present an analysis of the transcriptional profile of the medial domain of the Arabidopsis gynoecium highlighting the developmental stages that immediately proceed ovule initiation, the earliest stages of seed development. more...

(Submitter supplied) The highly conserved plant microRNA, miR156, is an essential regulator for plant development. We found miR156 changed gradually during leaf development. To find how miR156 regulated genes temporally, we analyzed the transcriptome of old and young leaves from miR156-overexpressed and wild type plants. The results show that the gradual increase of miR156 regulates temporal changes of numerous gene expressions during leaf development.
