A key question in developmental biology is how cells exchange positional information for
proper patterning during organ development. In plant roots the radial tissue organization is …

Plants and animals produce modular developmental units in a periodic fashion. In plants,
lateral roots form as repeating units along the root primary axis; however, the developmental …

This article deals with the origin and evolution of the DOF transcription factor family through
a phylogenetic analysis of those DOF sequences identified from a variety of representative …

Stem cells are defined by their ability to self-renew and produce daughter cells that proliferate
and mature. These maturing cells transition from a proliferative state to a terminal state …

Roots normally grow in darkness, but they may be exposed to light. After perceiving light,
roots bend to escape from light (root light avoidance) and reduce their growth. How root light …

In nature roots grow in the dark and away from light (negative phototropism). However, most
current research in root biology has been carried out with the root system grown in the …

Tissue patterns are dynamically maintained. Continuous formation of plant tissues during
postembryonic growth requires asymmetric divisions and the specification of cell lineages. We …

Many genomic-scale datasets in plants have been generated over the last few years. This
substantial achievement has led to impressive progress, including some of the most detailed …

In Arabidopsis thaliana, lateral roots initiate in a process preceded by periodic gene expression
known as the root clock. We identified the vesicle-trafficking regulator GNOM and its …

Postembryonic organogenesis is critical for plant development. Underground, lateral roots (LRs)
form the bulk of mature root systems, yet the ontogeny of the LR primordium (LRP) is not …
