Synthetic composites versus calcium phosphate cements in bone regeneration: A narrative review.

Background: When the natural process of bone remodeling is disturbed, the need arises for a stimulant material in order to enhance the formation of a new healthy and strong osseous tissue to replace the damaged one. Recent studies have reported synthetic biomaterials to be a very good option for supporting bone regeneration.

Study Design: Narrative review.

EU legal proposal for genome-edited crops hints at a science-based approach.

The European Commission (EC) recently published a legislative proposal that hints at a science-based approach to the regulation of genome-editing applications in crops in the EU. This would be in line with legislation in an increasing number of countries worldwide, but further science-based advice on implementation will be essential.

Interactive database of genome editing applications in crops and future policy making in the European Union.

European R&D in plant breeding is lagging behind, bound by strict genetically modified organism (GMO) regulations, applied to all crop varieties obtained with genome editing techniques. We developed an online database of worldwide genome editing applications in crops to support conclusions and to facilitate science-based policy making for this plant breeding innovation.

The role of scientists in policy making for more sustainable agriculture.

Dima and Inzé discuss how Europe is lagging behind in embracing the potential of genome editing in crops and highlight how scientists can contribute to advising on effective science-based policies for more sustainable agriculture through genome editing.

Small glycosylated lignin oligomers are stored in Arabidopsis leaf vacuoles.

Lignin is an aromatic polymer derived from the combinatorial coupling of monolignol radicals in the cell wall. Recently, various glycosylated lignin oligomers have been revealed in Arabidopsis thaliana. Given that monolignol oxidation and monolignol radical coupling are known to occur in the apoplast, and glycosylation in the cytoplasm, it raises questions about the subcellular localization of glycosylated lignin oligomer biosynthesis and their storage.

Systematic structural characterization of metabolites in Arabidopsis via candidate substrate-product pair networks.

Plant metabolomics is increasingly used for pathway discovery and to elucidate gene function. However, the main bottleneck is the identification of the detected compounds. This is more pronounced for secondary metabolites as many of their pathways are still underexplored.

Arabidopsis WAT1 is a vacuolar auxin transport facilitator required for auxin homoeostasis.

The plant hormone auxin (indole-3-acetic acid, IAA) has a crucial role in plant development. Its spatiotemporal distribution is controlled by a combination of biosynthetic, metabolic and transport mechanisms. Four families of auxin transporters have been identified that mediate transport across the plasma or endoplasmic reticulum membrane.

Visualization of plant cell wall lignification using fluorescence-tagged monolignols.

Lignin is an abundant phenylpropanoid polymer produced by the oxidative polymerization of p-hydroxycinnamyl alcohols (monolignols). Lignification, i.e.

Mass spectrometry-based fragmentation as an identification tool in lignomics.

The ensemble of all phenolics for which the biosynthesis is coregulated with lignin biosynthesis, i.e., metabolites from the general phenylpropanoid, monolignol, and (neo)lignan biosynthetic pathways and their derivatives, as well as the lignin oligomers, is coined the lignome.

Mass spectrometry-based sequencing of lignin oligomers.

Although the primary structure of proteins, nucleic acids, and carbohydrates can be readily determined, no sequencing method has been described yet for the second most abundant biopolymer on earth (i.e. lignin).
