Horizontal Transfer of Symbiosis Genes within and Between Rhizobial Genera : Occurrence and Importance [PDF]
Rhizobial symbiosis genes are often carried on symbiotic islands or plasmids that can be transferred (horizontal transfer) between different bacterial species. Symbiosis genes involved in horizontal transfer have different phylogenies with respect to the

Grazing limits natural biological controls of woody encroachment in Inner Mongolia Steppe
Woody encroachment in grasslands has become increasingly problematic globally. Grazing by domestic animals can facilitate woody encroachment by reducing competition from herbaceous plants and fire frequency.

Global variability in hydraulic traits and water use strategies of mountain shrubs and dwarf shrubs
Shrubs show a wide range of hydraulic strategies to achieve a balanced and favourable water status in mountain areas. Abstract Shrubs are perennial, multi‐stemmed woody plants whose adaptation to stress factors allows them to colonise extreme habitats, including high elevations. Accordingly, shrubs are one of the most important growth forms in mountain

ABSTRACT Ecosystem services (ES) play a crucial role in sustainable development. We systematically assessed the spatial and temporal dynamics of ecosystem service supply (ES‐s) and demand (ES‐d) in China from 1990 to 2020 by using a supply–demand matrix integrated with land use/cover data. The findings indicate that in 2020, grasslands accounted for 28.

Groundwater Altered Water Balance and Plant Water Use Efficiency in Desert Ecosystems
Abstract Groundwater is an important water source in water‐limited desert ecosystem. Less attention has been paid to how the water balance and plant performance in such ecosystems vary with the presence or absence of groundwater. Appropriate replanting strategies play a pivotal role in preventing desertification.
