Biochemical and systematic study of the genus Betula L.

Acta Societatis Botanicorum Poloniae, 2014
The division of the genus Betula L. accomplished on the basis of the flavonoid composition characteristic for the particular species; the proposed systematic classification also takes the chromosome number and geographical distribution into account.

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

New Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Woody Plant Diversity and Community Structure Along Elevational and Soil Gradients in Betula platyphylla Forests, Southeastern Tibetan Plateau

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study investigates the species composition, distribution, and diversity of Betula platyphylla forests in the Nyang River Basin in southeastern Tibet. The results show that elevation is the primary factor influencing species diversity in plant communities, with diversity indices significantly decreasing with increasing elevation.

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Chromosome‐Level Genome and Organ‐Specific Transcriptome of Alnus glutinosa Uncover Lineage‐Specific Innovations in Root Nodule Symbiosis

Plant, Cell &Environment, Volume 49, Issue 6, Page 3003-3021, June 2026.
ABSTRACT Alnus glutinosa is one of only three lineages within the order Fagales capable of establishing root nodule symbiosis (RNS). Although a fragmented genome assembly of A. glutinosa was previously available, its limited quality, combined with the lack of comprehensive transcriptomic resources, has constrained in‐depth comparative and functional ...
