The plant hormone auxin is a central regulator of plant growth and development. Because
auxin plays critical roles in cell division and cell expansion, plants use a number of cellular …

Plant development under altered nutritional status and environmental conditions and during
attack from invaders is highly regulated by plant hormones at the molecular level by various …

Inadequate availability of inorganic phosphate (Pi) in the rhizosphere is a common
challenge to plants, which activate metabolic and developmental responses to maximize Pi …

The endodermis is a root cell layer common to higher plants and of fundamental importance
for root function and nutrient uptake. The endodermis separates outer (peripheral) from inner …

The root cap has a central role in root growth, determining the growth trajectory and
facilitating penetration into the soil. Root cap cells have specialized functions and …

In this review, we analyze progress in understanding the mechanisms of root meristem
development and function. The formation of embryonic and lateral roots, together with the …

Levels of auxin, which regulates both cell division and cell elongation in plant development,
are controlled by synthesis, inactivation, transport, and the use of storage forms. However …

Primary plant meristems are the shoot and root meristems that are initiated at opposite poles
of the plant embryo. They contain stem cells, which remain undifferentiated, and supply new …

Although the quiescent center (QC) is crucial to root development, the molecular
mechanisms that regulate its postembryonic maintenance remain obscure. In this study, a …

Somatic embryogenesis involves a broad repertoire of genes, and complex expression
patterns controlled by a concerted gene regulatory network. The present work describes this …
