A feedforward loop controls vascular regeneration and tissue repair through local auxin biosynthesis (Plant Cell)

March 27, 2020 in /by

Plant cells are entrapped in rigid cell walls, so morphogenesis relies on asymmetric cell division (ACD) and positional cues to regulate tissue patterning. The Arabidopsis phloem is a good system to study tissue patterning due to its relatively simple composition: sieve elements (SEs) and companion cells (CCs) lineages. Although the regulatory programs that control phloem […]

A feedforward loop controls vascular regeneration and tissue repair through local auxin biosynthesis (Development)

March 20, 2020 in /by

Plants are constantly exposed to biotic and biotic stresses that can cause tissue damage, and, as a response, plants have evolved remarkably plastic regenerative mechanisms in response to wounding. Although some genes required for regeneration have been identified in the Arabidopsis root context, most notably PLETHORA (PLT) genes, the molecular players required for wound repair […]
