Body regeneration through formation of new organs is a major question in developmental biology. We investigated de novo root using whole leaves Arabidopsis (Arabidopsis thaliana). Our results show that local cytokinin biosynthesis and auxin the leaf blade followed by long-distance transport to petiole leads proliferation J0121-marked xylem-associated tissues others signaling INDOLE-3-ACETIC ACID INDUCIBLE28 (IAA28), CRANE (IAA18), WOODEN LEG, ARABIDOPSIS RESPONSE REGULATORS1 (ARR1), ARR10,...
In Arabidopsis, the root clock regulates spacing of lateral organs along primary through oscillating gene expression. The core molecular mechanism that drives periodicity and how it is modified by exogenous cues such as auxin gravity remain unknown. We identified key elements oscillator (AUXIN RESPONSE FACTOR 7, its auxin-sensitive inhibitor IAA18/POTENT, auxin) form a negative regulatory loop circuit in oscillation zone. Through multilevel computer modeling fitted to experimental data, we...
Summary Plant growth and development require a continuous balance between cell division differentiation. In root meristems, differentiated cells acquire specialized functions, losing their mitotic potential. Some plant cells, such as pericycle have remarkable plasticity to regenerate new organs. The molecular mechanisms underlying reprogramming are not completely known. this work, functional screening of transcription factors identified Arabidopsis OBP 4 (OBF Binding Protein 4) novel...
ABSTRACT Stem cells are central to plant development. During root postembryonic development stem generating tissues patterned in layers around a cell organizer or quiescent center (QC). How lineages initially is unclear. Here, we describe role for BLUEJAY (BLJ), JACKDAW (JKD) and SCARECROW (SCR) transcription factors patterning of during growth reestablishment regeneration through regulation number QC their regenerative capacities.

1. ABSTRACT Lateral root growth occurs from primed xylem pole pericycle cells that can be specified as founder cells, but how these acquire the pluripotency state to initiate a organogenesis program is not fully understood. Here, we find EMS 204 mutant unable specify due point mutation affecting C-terminal HDS3 domain of GNOM protein. We used genetics and cell biology study trafficking machinery in which primarily associated with recycling endosomes. found lack negatively affects stability...
