Giant pandas and red are endangered species with similar specialized bamboo diet partial sympatric distribution in China. Over the last two decades, rapid development of genomics metagenomics research on these has enriched our knowledge their biology, ecology, physiology, genetics, evolution, which is crucial useful for conservation. We describe evolutionary history, endangerment processes, genetic diversity, population structure wild giant (Chinese Himalayan pandas). In addition, we explore how studies have provided insight into convergent adaptation to diet. Finally, discuss findings applied effective conservation management captivity promote long-term persistence species.

Abstract Background Cetaceans, having experienced prolonged adaptation to aquatic environments, have undergone evolutionary changes in their respiratory systems. This process of evolution has resulted the emergence distinctive phenotypic traits, notably abundance elastic fibers and thickened alveolar walls lungs, which may facilitate collapse during diving. structure helps selective exchange oxygen carbon dioxide, while minimizing nitrogen exchange, thereby reducing risk DCS. Nevertheless, scientific inquiry into mechanisms through these unique characteristics govern diving behavior marine mammals, including cetaceans, remains unresolved. Results study entails an analysis 42 genes associated with pulmonary fibrosis across 45 mammalian species. Twenty-one cetaceans exhibited accelerated evolution, featuring specific amino acid substitutions 14 them. Primarily linked development system lung morphological construction, play a crucial role. Moreover, among we identified eight undergoing positive selection, rates three significantly correlated depth. Specifically, SFTPC gene convergent substitutions. Through vitro cellular experiments, illustrated that site mutations contribute positively presence this phenotype can induce deep diving, DCS Conclusions The unveils pivotal genetic signals other arising evolution. These influence mammals been reduced developing research serves as valuable reference for delving deeper human physiology.

Translation, a fundamental process regulating cellular growth and proliferation, relies on functional ribosomes. As sessile organisms, plants have evolved adaptive strategies to maintain delicate balance between stress response. But the underlying mechanisms, particularly translational level, remain less understood. In this study, we revealed mechanisms of AtPRMT3-RPS2B in orchestrating ribosome assembly managing regulation. Through forward genetic screen, identified PDCD2-D1 as suppressor gene restoring abnormal development biogenesis atprmt3-2 mutants. Our findings confirmed that PDCD2 interacts with AtPRMT3-RPS2B, facilitates pre-ribosome transport through nuclear pore complex, finally ensuring normal translation cytoplasm. Additionally, dysfunction was found enhance freezing tolerance. Moreover, promotes housekeeping mRNAs while concurrently repressing stress-related mRNAs. summary, our study sheds light regulatory roles balance, enabling trade-off stress. Ribosome are essential processes for activity. Here, authors illustrated role maintaining coordinating growth-stress trade-off.

Ecological restoration of mangrove ecosystems that became susceptible to recent habitat perturbations is crucial for tropical coast conservation. The white Laguncularia racemosa, a pioneer species inhabiting intertidal environments the Atlantic East Pacific (AEP) region, has been used reforestation in China decades. However, molecular mechanisms underlying its fast growth and high adaptive potential remain unknown. Using PacBio single-molecule real-time sequencing, we completed high-quality L. racemosa genome assembly covering 1105 Mb with scaffold N50 3.46 Mb. Genomic phylogeny shows invaded zones during period global warming. Multi-level genomic convergence analyses between three native dominant clades show they experienced convergent changes genes involved nutrient absorption salinity tolerance. This may explain successful adaptation stressful after introduction. Without whole-genome duplications or activated transposable elements, retained many tandem gene duplications. Some them are auxin biosynthesis, intense light stress cold response pathways, associated racemosa's ability grow under conditions when reforestation. In summary, our study identifies shared environmental unique genetic mangrove-unfavourable sheds on utility ecological restoration.
