Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

Advanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis.

American-Eurasian journal of botany, 2005
Chloroplast DNA sequences are a primary source of data for plant molecular systematic studies. A few key papers have provided the molecular systematics community with universal primer pairs for noncoding regions that have dominated the field, namely trnL-

ZNHIT3 Regulates Translation to Ensure Cell Lineage Differentiation in Mouse Preimplantation Development

Advanced Science, EarlyView.
Box C/D snoRNP complex regulates protein translation. This study identifies ZNHIT3 as a key component of the complex and ensures normal protein expression, including transcription factors orchestrating cell fate commitment, during early mouse embryogenesis.

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

PhyloSift: phylogenetic analysis of genomes and metagenomes

PeerJ, 2014
Like all organisms on the planet, environmental microbes are subject to the forces of molecular evolution. Metagenomic sequencing provides a means to access the DNA sequence of uncultured microbes.

Hierarchical Regulatory Networks Reveal Conserved Drivers of Plant Drought Response at the Cell‐Type Level

Advanced Science, EarlyView.
This study presents a comprehensive multi‐omics framework to uncover cell‐type‐specific regulatory networks in plant drought responses. By integrating transcriptomic, proteomic, and epigenetic data from nearly 30 000 samples, key regulators such as CIPK23 and NLP7 are identified, revealing insights into conserved drought tolerance mechanisms and ...

Suitability of Natura 2000 sites for threatened freshwater species under projected climate change

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1872-1887, December 2022., 2022
Abstract As part of the world's largest coordinated network of protected areas, Natura 2000, European Union member states designate special areas of conservation (SACs) to maintain or achieve favourable conservation status for imperilled aquatic species listed under Annex II of the Habitats Directive.

Phylogenetic Analysis of Nuclear-Encoded RNA Maturases

Evolutionary Bioinformatics, 2017
Posttranscriptional processes, such as splicing, play a crucial role in gene expression and are prevalent not only in nuclear genes but also in plant mitochondria where splicing of group II introns is catalyzed by a class of proteins termed maturases ...
