Sophisticated regulation of gene expression, including microRNAs (miRNAs) and their
target genes, is required for leaf differentiation, growth, and senescence. The impact of …

Leaf development has been extensively studied on a genetic level. However, little is known
about the interplay between the developmental regulators and the cell cycle machinery—a …

Originally identified in a genetic screen, microRNA miR319 regulates transcription factors of
the TCP family. The balance between miR319 and its targets controls leaf morphogenesis …

In a genetic screen in a drnl-2 background, we isolated a loss-of-function allele in miR319a
(miR319a129). Previously, miR319a has been postulated to play a role in leaf development …

The tremendous diversity of leaf shapes has caught the attention of naturalists for centuries.
In addition to interspecific and intraspecific differences, leaf morphologies may differ in …

Abstract CUP-SHAPED COTYLEDON2 (CUC2) and the interacting microRNA miR164
regulate leaf margin dissection. Here, we further investigate the evolution and the specific …

Coordination of the maintenance of the undifferentiated fate of cells in the shoot meristem
and the promotion of cellular differentiation in plant organs is essential for the development …

The characteristic leaf shapes we see in all plants are in good part the outcome of the
combined action of several transcription factor networks that translate into cell division …

Abstract CUP-SHAPED COTYLEDON1 (CUC1), CUC2, and CUC3 define the boundary
domain around organs in the Arabidopsis thaliana meristem. CUC1 and CUC2 transcripts …

Abstract Background: MicroRNAs (miRNAs) are∼ 21 nucleotide (nt) RNAs that regulate
gene expression in plants and animals. Most known plant miRNAs target transcription …
