Quantitative analysis of Trichodina denticlating characters and phylogenetic relationship studies on interspecies and intraspecies

open access: yes, 2004
Since Ehrenberg (1838) firstly reported Tricodina pediculus,there were two milestones in the research work on trichodinids. The first was the widespread acceptance of the uniform specific characteristics proposed by Lom (1958), which resulted in a ...

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

open access: yesAdvanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

The relationship between phylogenetic similarity and phylogenetic turnover along five spatial scales for BCI and DHS.

open access: yes, 2014
The relationship between phylogenetic similarity and phylogenetic turnover based on spatial simultaneous autoregressive error model across scales for the BCI (A) and DHS (B) plots. Y-axis is regression coefficient of ses.RaoD against NRI. The independent

A Conserved DT2‐bZIP66‐NF‐YC4 Regulatory Module Confers Drought Tolerance in Rice and Arabidopsis

open access: yesAdvanced Science, EarlyView.
This study identifies a conserved tripartiteDT2–bZIP66–NF‐YC4 transcriptional module that enhances rice drought tolerance by activating stress‐responsive genes. This regulatory complex is functionally conserved across cereals and Arabidopsis, providing promising targets for engineering drought‐resilient crops. ABSTRACT Drought stress severely restricts

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

open access: yesAdvanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

open access: yesAdvanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Phylogenetic analyses and taxonomic studies of Senecioninae : southern African Senecio section Senecio

open access: yes, 2009
Molecular phylogenetic analyses of subtribe Senecioninae, based on combining sequenced ITS and trnL-F fragments from specimens collected in the field with sequences collected from GenBank, suggest the subtribe is monophyletic, as is Senecio s.str ...

Relationship between the Phylogenetic Species Clustering index (PSC) and elevation.

open access: yes, 2012
Relationship between PSC and elevation. Assemblages showing statistically significant patterns of phylogenetic evenness are represented with black filled circles, those with phylogenetic clustering in gray circles, and those showing patterns not ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

open access: yesAdvanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...
