The evolution of drought tolerance in silver fir: evidence from genetics, physiology and common garden experiments
1H-NMR metabolomic profiling reveals a distinct metabolic recovery response in shoots and roots of temporarily drought-s...
Yield formation in regions with intermittent drought periods depends on the plant's ability to recover after cessation of the stress. The present work assessed differences in metabolic recovery of leaves and roots of drought-stressed sugar beets with high temporal resolution. Plants were subjected to drought for 13 days, and rewatered for 12 days. ...
NAD+ Biosynthesis and Signaling in Plants
Etude de la réponse de l’activité photosynthétique au déficit hydrique d’une collection de diversité de pommiers par étu...
Une étude fine de l’évolution de variables écophysiologiques en réponse à un déficit hydrique modéré au champ a été réalisé sur un panel de 8 génotypes sélectionné au sein d’une collection de diversité rassemblant 242 génotypes de pommiers à couteau. Cette étude bas-débit a servi de base pour calibrer une mesure haut débit d’un proxy de l’assimilat...
From structure to function - a family portrait of plant subtilases
...
Subtilases (SBTs) are serine peptidases that are found in all three domains of life. As compared with homologs in other Eucarya, plant SBTs are more closely related to archaeal and bacterial SBTs, with which they share many biochemical and structural features. However, in the course of evolution, functional diversification led to the acquisition of...
eIF4E-mediated resistance to viruses: from natural variation to synthetic alleles
eIF4E translation initiation factors have emerged as major susceptibility factors for RNA viruses. Natural eIF4E-based resistance alleles are found in many species and are mostly variants that maintain the translation function of the protein. eIF4E genes represent major targets for engineering viral resistance, and gene-editing technologies can be ...
Life and death of proteins after protease cleavage: protein degradation by the N-end rule pathway
The N-end rule relates the stability of a protein to the identity of its N-terminal residue and some of its modifications. Since its discovery in the 1980s, the repertoire of N-terminal degradation signals has expanded, leading to a diversity of N-end rule pathways. Although some of these newly discovered N-end rule pathways remain largely unexplor...

Validation of molecular markers associated with perpetual flowering in Octoploid Fragaria germplasm
...Published in Molecular Breeding
Perpetual-flowering (PF) is a highly desirable trait within cultivated strawberries (Fragaria ×ananassa) for the commercial and home garden markets. The most widely used source of the PF trait was originally introgressed from a wild F. virginiana subsp. glauca accession collected in the Wasatch Mountains near Salt Lake City, UT in 1955. This source...
Exploiting the Genetic Diversity of Maize Using a Combined Metabolomic, Enzyme Activity Profiling, and Metabolic Modelin...
...Published in The Plant cell
A combined metabolomic, biochemical, fluxomic, and metabolic modeling approach was developed using 19 genetically distant maize (Zea mays) lines from Europe and America. Considerable differences were detected between the lines when leaf metabolic profiles and activities of the main enzymes involved in primary metabolism were compared. During grain ...
