Spatiotemporal distribution patterns of soil nematodes along an altitudinal gradient in the cold temperate zone of China

Global Ecology and Conservation, 2023
As important components of the cosmopolitan soil biota, soil nematodes are found at multiple trophic levels of the belowground food web and play an important role in soil function.

Third-generation sequencing found LncRNA associated with heat shock protein response to heat stress in Populus qiongdaoensis seedlings

BMC Genomics, 2020
Background As air temperatures increase globally, more and more plants are exposed to heat-stress conditions. Although many studies have explored regulation networks in plants with the aim of improving their heat-stress tolerance, only few have revealed ...

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Insight into the Phylogenetic Relationships and Evolutionary History of Indocalamus (Bambusoideae) Through Comparative Analyses of Plastomes

Horticulturae
Indocalamus Nakai, a genus within the tribe Arundinarieae, has significant horticultural and economic value. However, its classification has long been challenging, and due to limited sampling, both intra- and intergeneric phylogenetic relationships, as ...

Transcriptome Profiling Reveals Differential Gene Expression of Secreted Proteases and Highly Specific Gene Repertoires Involved in Lactarius–Pinus Symbioses

Frontiers in Plant Science, 2021
Ectomycorrhizal fungi establish a mutualistic symbiosis in roots of most woody plants. The molecular underpinning of ectomycorrhizal development was only explored in a few lineages.

Species, Genes, and the Tree of Life [PDF]

, 2009
A common view is that species occupy a unique position on the Tree of Life. Evaluating this claim this requires an understanding of what the Tree of Life represents.

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 ...

Understanding Water Utilization Mechanisms in Degrading Bamboo Shoots: A Cytological and Physiological Study

Plants
Degradation of shoots, characterized by stunted growth and signs of water deficit, is common in bamboo stands. However, the specific mechanisms underlying water utilization in degrading shoots remain unclear.
