The role of elastic stresses on leaf venation morphogenesis [PDF]
, 2007 We explore the possible role of elastic mismatch between epidermis and mesophyll as a driving force for the development of leaf venation. The current prevalent 'canalization' hypothesis for the formation of veins claims that the transport of the hormone auxin out of the leaves triggers cell differentiation to form veins. Although there is evidence that

Auxin-induced growth inhibition a natural consequence of two-point attachment [PDF]
, 1952 It is characteristic of a great number of biologically active substances that the responses which they elicit are twofold, low concentrations of the material promoting a particular activity, and higher concentrations inhibiting it.

Is Enhancer Function Driven by Protein–Protein Interactions? From Bacteria to Leukemia
BioEssays, EarlyView.Enhancers are key regulatory elements that are conceptually conserved from bacteria to humans. Enhancer dysregulation is common in cancers, including leukemia. We argue that highly specific protein–protein interactions, including transcription factors, mediate enhancer‐promoter proximity to allow enhancer‐bound factors to directly act on RNA polymerase

UGT74D1 is a novel auxin glycosyltransferase from Arabidopsis thaliana. [PDF]
PLoS ONE, 2013 Auxin is one type of phytohormones that plays important roles in nearly all aspects of plant growth and developmental processes. The glycosylation of auxins is considered to be an essential mechanism to control the level of active auxins.

The ARF-AID system: Methods that preserve endogenous protein levels and facilitate rapidly inducible protein degradation [PDF]
arXiv, 2020 The ARF-AID (Auxin Response Factor-Auxin Inducible Degron) system is a re-engineered auxin-inducible protein degradation system. Inducible degron systems are widely used to specifically and rapidly deplete proteins of interest in cell lines and organisms. An advantage of inducible degradation is that the biological system under study remains intact and

Mathematical Modelling of Auxin Transport in Plant Tissues: Flux meets Signalling and Growth [PDF]
arXiv, 2018 Plant hormone auxin has critical roles in plant growth, dependent on its heterogeneous distribution in plant tissues. Exactly how auxin transport and developmental processes such as growth coordinate to achieve the precise patterns of auxin observed experimentally is not well understood.

Cytoskeleton, EarlyView.ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

Quantitative predictions on auxin-induced polar distribution of PIN proteins during vein formation in leaves [PDF]
Eur. Phys. J. E 33, 165 (2010), 2010 The dynamic patterning of the plant hormone auxin and its efflux facilitator the PIN protein are the key regulator for the spatial and temporal organization of plant development. In particular auxin induces the polar localization of its own efflux facilitator.
