Microsystems & Nanoengineering, 2022 For plants on Earth, the phytohormone auxin is essential for gravitropism-regulated seedling establishment and plant growth. However, little is known about auxin responses under microgravity conditions due to the lack of a tool that can provide an ...

Plants, 2021 We explored the interplay between ethylene signals and the auxin pool in roots exposed to high salinity using Arabidopsisthaliana wild-type plants (Col-0), and the ethylene-signaling mutants ctr1-1 (constitutive) and ein2-1 (insensitive).

Mechanism of dynamic reorientation of cortical microtubules due to mechanical stress [PDF]
Biophysical Chemistry 207, 82-89 (2015), 2015 Directional growth caused by gravitropism and corresponding bending of plant cells has been explored since 19th century, however, many aspects of mechanisms underlying the perception of gravity at the molecular level are still not well known. Perception of gravity in root and shoot gravitropisms is usually attributed to gravisensitive cells, called ...

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

BMC Plant Biology, 2019 Background Auxin conjugates are hydrolyzed to release free auxin to ensure defined cellular auxin levels or gradients within tissues for proper development or response to environmental signals.

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.

Both Induction and Morphogenesis of Cyst Nematode Feeding Cells Are Mediated by Auxin
Molecular Plant-Microbe Interactions, 2000 Various lines of evidence show that local changes in the auxin concentration are involved in the initiation and directional expansion of syncytia induced by cyst nematodes.

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.

Phyllotaxis, Pushed Pattern-Forming Fronts and Optimal Packing [PDF]
, 2013 We demonstrate that the pattern forming partial differential equation derived from the auxin distribution model proposed by Meyerowitz, Traas and others gives rise to all spiral phyllotaxis properties observed on plants. We show how the advancing pushed pattern front chooses spiral families enumerated by Fibonacci sequences with all attendant self ...
