The tree, the network, and the species [PDF]

Biological Journal of the Linnean Society, 2006
To enrich the Hennigian internodal conception of species, a new formalization of the definition of the species concept is proposed. This rigorous definition allows for considerable unification of the various, and sometimes conflicting, techniques of species delimitation used in practice.

Mechanistic insights into adventitious root formation in Cinnamomum kanehirae stem cuttings based on phenotypic, physiological, and transcriptomic analyses

BMC Plant Biology
Cinnamomum kanehirae is a species of high economic worth, as it produces abundant aromatic oils for industrial use and its heartwood acts as an optimal substrate for cultivating the medicinal fungus Antrodia cinnamomea.

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 ...

Ammonium assimilation inhibitors weaken the growth of moso bamboo seedlings through metabolic dysregulation [PDF]

PeerJ
Background The uncontrolled expansion of moso bamboo (Phyllostachys edulis) in subtropical regions threatens forest ecosystem integrity and biodiversity, yet effective control measures are lacking.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

New Combination and Two Synonyms of Indocalamus Nakai (Poaceae: Bambusoideae) from China Based on Morphological Characters and Phylogenetic Evidence

Taxonomy
Based on several sources of evidence from morphology, the micromorphology of the abaxial leaf epidermis, and a phylogenetic analysis using complete chloroplast genome data, a new combination and two new synonyms are reported in the genus Indocalamus ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Chromosome-level genome assembly of Nothapodytes nimmoniana

Scientific Data
Nothapodytes nimmoniana is a plant species belonging to the genus Nothapodytes in the family Icacinaceae. This species holds significant medicinal value due to its camptothecin content. In this study, we present the first chromosome-level genome assembly

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Evolution of Plant AIG1-like Proteins: Different Modes of Sequence Divergence and Their Contributions to Functional Diversification

Plants
AIG1 (avrRpt2-induced gene 1)-like proteins are a class of GTPases that play crucial roles in plants, functioning both in chloroplast protein import and disease resistance.
