Secondary growth from vascular cambia results in radial, woody growth of stems. The
innovation of secondary vascular development during plant evolution allowed the …

The ribosomal protein S27a (RPS27a) is cleaved from the fusion protein ubiquitin–RPS27a
(Ub–RPS27a). Generally, Ub and RPS27a are coexpressed as a fusion protein but function …

Cells of eukaryotic multicellular organisms have inherent heterogeneity. Recent advances in
single-cell gene expression studies enable us to explore transcriptional regulation in …

Plant height (PH) is a key factor in maize (Zea mays L.) yield, biomass, and plant
architecture. We investigated the PH of diverse maize inbred lines (117 temperate lines, 135 …

Development in higher plants depends on the activity of meristems, formative regions that
continuously initiate new organs at their flanks. Meristems must maintain a balance between …

Abstract Calcium (Ca 2+) is an intracellular second messenger involved in many signal
transduction pathways in plants. The perception of environmental and internal cues leads to …

Root growth is maintained by the continuous division of cells in the apical meristem. ROOT
MERISTEM GROWTH FACTOR 1 (RGF1) is a critical peptide hormone regulating root stem …

The miR166/165 group and its target genes regulate diverse aspects of plant development,
including apical and lateral meristem formation, leaf polarity, and vascular development. We …

In Arabidopsis, two floral homeotic genes APETALA2 (AP2) and AGAMOUS (AG) specify the
identities of perianth and reproductive organs, respectively, in flower development. The two …

Cytokinins stimulate shoot regeneration in tissue culture but the genes required for this
developmental process are not well understood. Here we show that the Arabidopsis gene …
