Adaptive Coordination Engineering for Efficient and Robust H2 Release

Advanced Science, EarlyView.
β‐H elimination is a pivotal but challenging step in homogeneous formic acid dehydrogenation reactions due to strict hydride‐metal matching. By using a rationally designed Pd1Ag2 bimetallic system with adaptive Pd1‐Ag2/L2 coordination and formate bridges, it enables boosted formic acid dehydrogenation under ambient air (7.7 times higher than a Pd ...

The principles of evolutionary and adaptive significance of the organization of species genomes and their use in selection

Фактори експериментальної еволюції організмів, 2013
Aims. The study of the genetic aspects of speciation and adaptation, wich was conducting by me for about 40 years, revealed a number of genetic parameters that distinguish evolutionarily labile species (speciation generators) and evolutionary ...

Adaptive responses drive the success of polyploid yellowcresses (Rorippa, Brassicaceae) in the Hengduan Mountains, a temperate biodiversity hotspot

Plant Diversity, 2022
Polyploids contribute substantially to plant evolution and biodiversity; however, the mechanisms by which they succeed are still unclear. According to the polyploid adaptation hypothesis, successful polyploids spread by repeated adaptive responses to new

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Proton‐Switching Regulates Interfacial Iodine Chemistry for Long‐Life Zinc–Iodine Batteries

Angewandte Chemie, EarlyView.
A proton‐switchable imine‐linked framework is developed to dynamically regulate interfacial iodine chemistry in aqueous Zn–I2 batteries, where reversible protonation/deprotonation switches the host affinity between iodide and polyiodide species. This state‐dependent regulation suppresses shuttle‐induced side reactions while preserving fast iodine redox

Speciation and adaptation of senecio

, 2020
Speciation was thought to be initiated by geographical isolation only. However, more and more research has shown that there are other drivers of speciation, such as divergent selection, and that speciation could happen in the face of gene flow with mechanisms to maintain reproductive isolation.

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

Angewandte Chemie, EarlyView.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

Speciation, Phenotypic Variation and Plasticity: What Can Endocrine Disruptors Tell Us?

International Journal of Endocrinology, 2013
Phenotype variability, phenotypic plasticity, and the inheritance of phenotypic traits constitute the fundamental ground of processes such as individuation, individual and species adaptation and ultimately speciation. Even though traditional evolutionary

Rewiring Pyroptosis to Potentiate Cancer Immunotherapy via a Gasdermin D Agonist Bypassing Caspase‐3

Advanced Science, EarlyView.
This work introduces a small‐molecule agonist, DIBDO, that bypasses Casp‐3 to directly trigger GSDMD‐mediated pyroptosis in tumors. Activated by glutathione, DIBDO generates singlet oxygen and molecular iodine, blocking Casp‐3 pathways and inducing immunogenic cell death.
