Viola shiweii Xiao C. Li & Z. W. Wang (Violaceae), a new species from Guizhou, China, is described, based on morphological and molecular evidence. The new species is morphologically most similar to V. kwangtungensis Melchior in its glabrous lateral petals and stoloniferous habit, but can be...

There are more than 36,000 described species in the family Cerambycidae in the world. With the significant increase of international trade in the recent decades, many cerambycid species have become major plant pests outside their natural distribution range, causing serious environmental problems at ...

Phytochemical investigation of Eucommia ulmoides Oliver staminate flowers provided twenty-seven compounds, including 11 triterpenes (1-11), 4 fatty acids (12-15), 1 coumarin (16), 1 chromone (17), 7 flavonoids (18-24) and 3 cyclopeptide alkaloids (25-27). Compounds 4-6, 8-9, 11-15, 17 and 25-27...

Different from leaf photosynthesis that depends on stomatal uptake of CO₂, stem green tissue mainly uses internal CO₂ for re-assimilation. Research attention has moved to its specific effect on xylem hydraulic function, however, the effect of stem corticular photosynthesis on whole-plant water...

Establishing the relationship between surface pollen assemblages and related modern vegetation provides a bridge for reconstructing the palaeo-vegetation succession and related climate changes. Numerous contributions have demonstrated an inconsistency between the relative abundance values of...

Separating centres of neo- and paleo-endemism on the clade level from the tree of life could infer their evolutionary history and further pinpoint conservation priorities. Yet, centres of neo- and paleo-endemism in mega-biodiversity China are controversial as their environmental features are...

Plants possess inherent mechanisms of dynamic responses to escape and/or adapt to adverse environmental stress. Small auxin upregulated RNA (SAUR) genes are a group of early auxin-responsive genes that play a crucial role in higher plant normal growth and environmental stimuli. The systematic...

The temporal heterogeneity of nitrogen availability in soils is increasing due to agricultural deposition. We here compared the effects of gradually increasing nitrogen deposition rate and its increasing temporal heterogeneity patterns on the functional traits of seedlings of exotic species Rhus...

Two new species of Boletopsis, B. macrocarpa and B. tibetana, are described and illustrated from Southwest (SW) China based on morphology, ecology and phylogenetic analyses by the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU). Boletopsis...
