Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The confinedness of undergrowth Picea obovata and Abies sibirica (Pinaceae) to tree-related microhabitats and their development features at various phases of post-fire succession in green-moss dark coniferous forests in the Northern Pre-Urals

Nature Conservation Research: Заповедная наука
Forest ecology frequently explores the role of microsite mosaics in forest communities for the regeneration of forest-forming tree species. The present study aims to find out whether the ontogenetic structure and differentiation of Siberian spruce (Picea

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Associations between forest vegetation and the fertility of soil organic horizons in northwestern Russia

Forest Ecosystems, 2019
Background Being the product of the same environment, soil and vegetation are mutually associated with each other, but the relationships between edaphic properties and vegetation characteristics are still far from clear.

RESPONSE OF TWO WHEAT CULTIVARS TO ROW SPACING AND NITROGEN FERTILIZATION LEVELS UNDER RECLAIMED SANDY SOILS [PDF]

Journal of Productivity and Development, 2011
Two field experiments were carried out in a private farm at Wadi El-Mollak region, Abo-Hammad District, Sharkia Governorate, during two winter seasons [2007/ 2008 and 2008/2009] in à reclamid sandy soil. This study aimed to invstigate the response of two
