Shoot meristems are maintained by pluripotent stem cells that are controlled by CLAVATA-
WUSCHEL feedback signaling. This pathway, which coordinates stem cell proliferation with …

Peptides fulfill a plethora of functions in plant growth, development, and stress responses.
They act as key components of cell-to-cell communication, interfere with signaling and …

The Arabidopsis root has been the subject of intense research over the past decades. This
research has led to significantly improved understanding of the molecular mechanisms …

Brassinosteroids (BRs) are natural plant hormones critical for growth and development. BR
deficient or signaling mutants show significantly shortened root phenotypes. However, for a …

Adventitious rooting (AR) is a multifactorial response leading to new roots at the base of
stem cuttings, and the establishment of a complete and autonomous plant. AR has two main …

Plant cells are connected through plasmodesmata (PD), membrane-lined channels that
allow symplastic movement of molecules between cells. However, little is known about the …

Stem vascular cambium cells in forest trees produce wood for materials and energy. WOX4
affects the proliferation of such cells in Populus. Here we show that Ptr WOX4a is the most …

The indeterminate nature of plant growth and development depends on the stem cell system
found in meristems. The Arabidopsis thaliana vascular meristem includes procambium and …

Background The root system of higher plants originates from the activity of a root meristem,
which comprises a group of highly specialized and long-lasting stem cells. Their …

The decade since the publication of the third edition of this volume has been an era of great
progress in biology in general and the plant sciences in particular. This is especially true …
