The Effects of Cytokinin on the Transcriptional Regulation of PIN Expression in Arabidopsis thaliana [PDF]
, 2012 The processes of cell division and differentiation are critical to the development of any multicellular organism. During the formation of plant roots these processes take place at a region of the root tip called the meristem.

Interplay of the two ancient metabolites auxin and MEcPP regulates adaptive growth. [PDF]
, 2018 The ancient morphoregulatory hormone auxin dynamically realigns dedicated cellular processes that shape plant growth under prevailing environmental conditions. However, the nature of the stress-responsive signal altering auxin homeostasis remains elusive.

Advanced Science, EarlyView.OsNRT1.1B forms a membrane complex with OsCNGC14/16 that mediates nitrate‐triggered calcium influx. This calcium signal phosphorylates OsNLP3 at Ser193, accelerating its nuclear translocation and activating nitrogen‐responsive genes. The calcium‐dependent pathway complements the established ubiquitination‐mediated pathway, dynamically regulating ...

Overexpression of the auxin binding protein1 modulates PIN-dependent auxin transport in tobacco cells. [PDF]
PLoS ONE, 2013 Auxin binding protein 1 (ABP1) is a putative auxin receptor and its function is indispensable for plant growth and development. ABP1 has been shown to be involved in auxin-dependent regulation of cell division and expansion, in plasma-membrane-related ...

Molecular genetics of auxin signaling [PDF]
, 2002 The plant hormone auxin is a simple molecule similar to tryptophan, yet it elicits a diverse array of responses and is involved in the regulation of growth and development throughout the plant life cycle.

A mathematical study of the transport of auxin
Mathematical Modelling, 1980 AbstractStarting with the one-dimensional equation of diffusion (Fick's equation) and the law governing transport across a membrane, the concentrations of auxin in the walls of n cells forming a linear array are expressed as infinite series in the time t for several stipulations of the concentration of auxin at the two ends of the array.

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics
Advanced Science, EarlyView.Small nanoplastics can disrupt cell integrity and inhibit cell division in meristem zone of plant root. The plants can counteract the cell damage by upregulating genes associated with root meristem maintenance and increasing auxin accumulation by PIN2 transport inhibition.

Diversification and expression of the PIN, AUX/LAX, and ABCB families of putative auxin transporters in \u3cem\u3ePopulus\u3c/em\u3e [PDF]
, 2012 Intercellular transport of the plant hormone auxin is mediated by three families of membrane-bound protein carriers, with the PIN and ABCB families coding primarily for efflux proteins and the AUX/LAX family coding for influx proteins. In the last decade

Transcriptional regulation of PIN genes by FOUR LIPS and MYB88 during Arabidopsis root gravitropism [PDF]
, 2015 PIN proteins are auxin export carriers that direct intercellular auxin flow and in turn regulate many aspects of plant growth and development including responses to environmental changes.
