Summary: The study conducted a comprehensive analysis of the evolution of insect beta-fructofuranosidase transferred through HGT, identifying posttransfer duplications in Lepidoptera and mutations affecting physiological function in Bombyx mori. These findings indicate that gene transfer enhances the digestive and metabolic adaptation of lepidopteran insects.

Summary: This study investigates the interactions of microbial communities in coastal waters in response to carbon, nitrogen, and metal pollution, as well as their effects on horizontal gene transfer. The results show that carbon, nitrogen, and metal significantly influence the distribution, diversity, and gene transfer of microbial communities in coastal waters, particularly under arsenic stress.

Summary: Specific leaf area (SLA) is a widely studied plant trait that reflects plant resource acquisition strategies. Despite consistent variation in SLA across different plateaus, short-term manipulative experiments showed that SLA increases with resource availability, suggesting an important strategy for grassland species in coping with ongoing shifts in climate.

Summary: This study investigated the spatial variation and adaptation of specific leaf area (SLA) in plant species in China. The results showed that SLA differed among different ecosystems, temperature zones, vegetation types, and functional groups. Phylogeny had a weak effect on SLA, but plant species evolved toward higher SLA. SLA responded nonlinearly to environmental change, and radiation was one of the main factors determining the spatial variation in SLA.

Summary: This study aimed to explore the impact of different disinfectants on the horizontal transfer of antibiotic resistance genes (ARGs) and their underlying mechanisms. The results showed that quaternary ammonium salt, organic halogen, alcohol, and guanidine disinfectants significantly facilitated the conjugative transfer, while heavy metals, peroxides, and phenols displayed an inhibitory effect. Furthermore, guanidine disinfectants promoted conjugation through increased cell membrane permeability, over-production of reactive oxygen species (ROS), enhanced SOS response, and altered expression of conjugative transfer-related genes. Moreover, guanidine disinfectants also promoted bacterial energy metabolism and flagellum motility. These findings highlight the potential risks caused by the massive use of guanidine disinfectants, especially during the COVID-19 pandemic.

Summary: Cells can acquire mitochondrial DNA (mtDNA) from other cells without a parent-offspring relationship, and this acquisition can occur at high levels. The transfer of mtDNA may serve as a compensatory mechanism to restore compromised mitochondrial function. These findings have important implications for understanding mtDNA transfer and developing gene therapies.

Summary: Horizontal gene transfer of heavy metal resistance genes and antibiotic resistance genes commonly occurred during composting. This study aimed to explore the relationship between heavy metal pollution and horizontal gene transfer during composting. The findings showed that heavy metal pollution induced a higher abundance of resistance genes in microorganisms and promoted the occurrence of horizontal gene transfer. The impact of pollution levels on the relevancy between resistance gene abundance and horizontal gene transfer was also analyzed.

Summary: This study investigates how light, nitrogen, and water availability influence the growth and physiology of different populations of koa trees across elevational gradients in Hawaii. The results suggest that multiple resource limitations can interact and impact the growth and physiology of koa populations, emphasizing the importance of considering multiple resource limitations in population-based guidelines for forest and tree species restoration.

Summary: Plants respond to low potassium levels by modulating the abundance and phosphorylation of proteins in CBL-CIPK-channel modules, with the CBL1/9-CIPK pathway promoting potassium uptake and the CBL2/3-CIPK pathway facilitating potassium remobilization. The phosphatases HAB1/ABI1/ABI2/PP2CA act as negative regulators of plant growth under low potassium conditions.

Summary: The concentration of dissolved organic nitrogen (DON) is increasing in many northern hemisphere lakes, yet its use by phytoplankton and fate in the environment seldom have been quantified. We conducted 1 week, in situ, microcosm incubations across 25 lakes in northeastern North America to understand how DON, dissolved inorganic nitrogen (DIN), and dissolved inorganic phosphorus (P) affected phytoplankton biomass. Phytoplankton biomass in 80% of lakes responded similarly to DON and DIN additions. Colimitation was the most common type of nutrient limitation among the study lakes, followed by P limitation.

Summary: Horizontal gene transfer is an important factor in bacterial evolution, allowing for rapid evolution and increased adaptation in recipient organisms. Adaptive evolution mainly occurs in populations with increased fitness, with HGT selection having a broad genetic basis and showing different types of selection in functional gene networks.

Summary: This study investigated the patterns of plant-microbial N/P limitation in forests across China and found significant divergence between the two. The N/P limitation was disconnected in 42.6% of plant-microbial communities, with only 17.7% of N and 39.7% of P limitations consistent. The divergence was more evident at mid-latitudes, where plants were mainly N limited and microbes were mainly P limited. The findings were consistent with ecological stoichiometry and highlighted the importance of soil chemistry in driving the divergence.

Summary: The study found that there are numerous Synechococcus amplicon sequence variants (ASVs) within the population at the Scripps Institution of Oceanography pier and in the Southern California coastal ecosystem. An anomalous bloom in August 2016 significantly increased the overall abundance of Synechococcus and introduced normally oligotrophic Synechococcus clade II into the population. This study also observed changes in clade and ASV composition during blooms, as well as more oligotrophic ASVs and clades further offshore.

Summary: In this study, 20 cyanobacterial strains were screened for the accumulation of carbon storage granules using Nile Red and BODIPY 493/503 dye-staining and fluorescence microscopy. Six strains were found to have dye-staining granules, with 4 strains confirmed to produce polyhydroxyalkanoate (PHA) granules through gene analysis. Horizontal gene transfer was observed between distant genera, shedding light on the evolutionary history of PHA biosynthesis in Cyanobacteria.

Summary: The study utilized various sequencing methods to quantify microbial abundances in water-column samples and sediment-trap-collected particles in the California Current Ecosystem. Results showed that most dominant eukaryotes and prokaryotes were underrepresented on sinking particles, while diatoms were consistently overrepresented. This highlights the importance of sequence-based quantitative approaches for assessing taxon contributions of phytoplankton to carbon export.

Summary: The microbial mat communities in the hot springs of the Black Canyon of the Colorado River were studied using both culture-independent and -dependent methods. The results showed that these communities are mainly composed of cyanobacterial taxa, along with a diverse community of protists and other eukaryotes. The use of full-length rRNA gene sequencing allowed for a higher resolution of the community, and correlation analysis supported the co-occurrence of cyanobacteria, chloroflexi, and bacteroidetes.
