The Rhus chinensis Genome Provides Insights Into Tannin, Flavonoid Biosynthesis, and Glandular Trichome Development

Plant Biotechnology Journal, Volume 24, Issue 3, Page 988-1013, March 2026.
ABSTRACT The “salt tree”, Rhus chinensis, holds significant economic and medicinal value due to its ability to produce Galla chinensis (Chinese gall/gallnut), a plant‐derived medicinal material used in both traditional Chinese and modern medicine that is rich in tannins and flavonoids. It is also renowned for its remarkable stress tolerance.

A novel circumscription and classification for Neurolaeneae (Asteraceae)

TAXON, Volume 75, Issue 1, February 2026.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...

Experimental methods for wind tunnel studies of seed dispersal by wind

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...
