Background: The St-genome-sharing taxa are highly complex group of the species with the St nuclear genome and monophyletic origin in maternal lineages within the Triticeae, which contains more than half of polyploid species that distributed in a wide range of ecological habitats. While high level of genetic heterogeneity in plastome DNA due to a reticulate evolutionary event has been considered to link with the richness of the St-genome-sharing taxa, the relationship between the dynamics of diversification and molecular evolution is lack of understanding.
Results: Here, integrating 106 previously and 12 newly sequenced plastomes representing almost all previously recognized genomic types and genus of the Triticeae, this study applies phylogenetic reconstruction methods in combination with lineage diversification analyses, estimate of sequence evolution, and gene expression to investigate the dynamics of diversification in the tribe.
Ribosome biogenesis is pivotal in the self-replication of life. In Escherichia coli, three ribosomal RNAs and 54 ribosomal proteins are synthesized and subjected to cooperative hierarchical assembly facilitated by numerous accessory factors. Realizing ribosome biogenesis in vitro is a critical milestone for understanding the self-replication of life and creating artificial cells.

Pathogenic variants in cytochrome oxidase assembly factor 5 (COA5), a proposed complex IV (CIV) assembly factor, have been shown to cause clinical mitochondrial disease with two siblings affected by neonatal hypertrophic cardiomyopathy manifesting a rare, homozygous missense variant (NM_001008215.3: c.157G>C, p.

Acute lung injury (ALI) is a complex acute respiratory illness with a high mortality rate. Reactive oxygen species (ROS) play a pivotal role in ALI, inducing cellular damage, inflammation, and oxidative stress, thereby exacerbating the severity of the injury. In this study, inspired by the "subtractive" strategy, we developed a fucoidan-based macrophage membrane bio-nanosystem, abbreviated as MF@CB, designed as an anti-inflammatory and antioxidant agent to alleviate lipopolysaccharide (LPS)-induced inflammation in ALI.

The Space Radiobiological Exposure Facility (SREF) is a general experimental facility at the China Space Station for scientific research in the fields of space radiation protection, space radiation biology, biotechnology, and the origin of life. The facility provides an environment with controllable temperatures for experiments with organic molecules and model organisms such as small animals, plant seeds, and microorganisms. The cultivation of small animals can be achieved in the facility with the use of microfluidic chips and images and videos of such experiments can be captured by microscopy.
