Over centuries of plant morphological research, biologists have enthusiastically explored
how distinct vascular arrangements have diversified. These investigations have focused on …

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

Current definitions of tracheids and vessel elements are overly simple. These definitions are
based on light microscope studies and have not incorporated information gained with …

Secondary phloem and xylem tissues are produced through the activity of vascular
cambium, the cylindrical secondary meristem which arises among the primary plant tissues …

The control of primary vascular tissue differentiation by auxin produced by the shoot apex
ranks among the better known hormone signaling systems in vascular plants. Surprisingly …

The morphology of plant fossils from the Rhynie chert has generated longstanding questions
about vascular plant shoot and leaf evolution, for instance, which morphologies were …

Secondary growth from a vascular cambium, present today only in seed plants and
isoetalean lycophytes, has a 400millionyr evolutionary history that involves considerably …

During leaf development, ground meristem cells along continuous lines undergo
coordinated oriented cell divisions and differentiate to form procambial cells, the precursors …

The stele concept is one of the oldest enduring concepts in plant biology. Here, I review the
history of the concept and build an argument for an updated view of steles and their …

Plant vascular tissues are organised in continuous strands, the longitudinal and radial
patterns of which are intimately linked to the signals that direct plant architecture as a whole …
