A theoretical investigation provides an integrated understanding of the complex regulatory network controlling Arabidopsis root hair patterning [PDF]

open access: yesarXiv
A complex regulatory network controlling Arabidopsis root hair patterning has been defined using data collected over decades. The network, embedded in the root epidermis, contains positive and negative feedback loops, cell-cell signalling within the epidermal tissue, and receives positional signalling from underlying tissue.

Computational Study on the Reaction Mechanism of 5‐Enolpyruvylshikimate‐3‐phosphate Synthase from Nicotiana Tabacum

open access: yesChemistryOpen, EarlyView.
The reaction mechanism of 5‐enolpyruvylshikimate‐3‐phosphate synthase from Nicotiana tabacum (NtEPSPS) is elucidated using quantum chemical calculations. The proposed mechanism involves four sequential steps: carbocation intermediate formation, tetrahedral intermediate formation, rate‐limiting C−O bond cleavage, and C=C bond re‐formation.

Arabidopsis roots segmentation based on morphological operations and CRFs [PDF]

open access: yesarXiv, 2017
Arabidopsis thaliana is a plant species widely utilized by scientists to estimate the impact of genetic differences in root morphological features. For this purpose, images of this plant after genetic modifications are taken to study differences in the root architecture.

Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Arabidopsis 3‐Deoxy‐d‐Arabino‐Heptulosonate 7‐Phosphate (DAHP) Synthases of the Shikimate Pathway Display Both Manganese‐ and Cobalt‐Dependent Activities

open access: yesPlant Direct
The plant shikimate pathway directs a significant portion of photosynthetically assimilated carbon into the downstream biosynthetic pathways of aromatic amino acids (AAA) and aromatic natural products.

The Actin‐Binding Prolyl‐Isomerase Par17 Sustains Its Substrate Selectivity by Interdomain Allostery

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The human peptidyl‐prolyl‐cis/trans isomerases (PPIases), Parvulin 14 and Parvulin 17, accelerate the cis/trans isomerization of Xaa‐Pro moieties within protein sequences. By modulating the respective binding interfaces of their target proteins, they play a crucial role in determining the fate of their substrates within the cell. Although both

2,4‐D resistance due to a deletion in IAA2 in Sisymbrium orientale L. carries no apparent fitness penalty

open access: yesPest Management Science, EarlyView.
A 27 bp deletion in SoIAA2 does not carry a measurable fitness penalty, either in monoculture or in competition with wheat. This suggests this mutation could be relatively common in weed populations. Abstract BACKGROUND A deletion mutation in the degron tail of auxin coreceptor IAA2 was found to confer resistance to the herbicide 2,4‐D in Sisymbrium ...
