Summary: Nitric oxide (NO) is a crucial signaling molecule in biological systems, playing important roles in cardiovascular, neurological, and immune functions. Understanding the evolution of NO synthases (Nos) genes, which produce NO in vivo, is still a puzzle, especially in fish compared to tetrapods. Recent studies have found the presence of nos3 gene, previously considered lost, in spotted gar, changing our perspective on the origin of nos genes. This study explored nos gene evolution in different vertebrate species and revealed lineage-specific gene duplications and losses, independent losses of nos3 in teleost lineages, and the expression of nos genes in the gills of certain gnathostome species. These findings provide insights into the roles and evolutionary history of nos genes.

Summary: The formation of new genes can occur through gene duplication or de novo formation from noncoding sequences. Both mechanisms show similarities in terms of low sequence constraints in the initial evolutionary stages, high turnover rates at the species level, and comparable persistence rates in deeper branches. Additionally, de novo proteins tend to have an excess of substitutions between charged amino acids, leading to rapid loss of their initial highly basic character.

Summary: This study conducted a comprehensive analysis of DDP proteins in the potato genome, identifying 10 DDP genes and studying their characteristics in terms of phylogenetics, gene duplication, expression profiles, and promoter regions involved in stress response. The research revealed that StDDP genes were distributed across different clades, and exhibited various expression patterns in response to heat stress and salt stress. Real-time qPCR results indicated that StDDPs played significant roles in potato growth and development.

Summary: The study reveals multiple gene duplications and intron gains within Caenogastropoda, indicating these as general features of Apogastropoda hemocyanins. While exon-intron structures are consistent within Tectipleura lineages, they vary significantly within Caenogastropoda and even among paralogous hemocyanin genes of the same species. This suggests that intron accumulation occurred gradually within Caenogastropoda, leading to a multitude of introns.

Summary: Studying the evolutionary history of gene families is important for understanding gene origin, evolution, and their implications for functional studies. The sirtuin gene family, involved in aging-related functions, has a complex duplicative history, but our results provide a well-resolved phylogeny and shed light on the repertoire of sirtuin genes among vertebrates. We identified a new member (SIRT3.2) that was lost in amniotes but retained in other jawed vertebrates, and its experimental analysis revealed its mitochondrial location and deacetylase activity similar to mammalian SIRT3.

Summary: This study found that longer internal exons tend to encode intrinsically disordered regions (IDRs) in eukaryotes. Based on this finding, the "small bang model" was proposed, suggesting that early eukaryotic genes lacked introns and mostly encoded single structural domains (SDs). However, through exon division and elongation, IDRs were acquired and eventually led to the last common ancestor of eukaryotes. This model explains the dichotomy between prokaryotic and eukaryotic proteins and highlights the selective advantage conferred by IDRs.

Summary: This study identified multiple gene families in plant genomes containing intronless or intron-poor genes, which play important roles in response to drought and salt stress, epigenetic processes, and plant development. The origin, evolution, and potential functions of these intronless and intron-poor sub-families provide insights into plant genome evolution and gene functional divergence.

Summary: The study characterized and evolution of three ss-1,4-endoglucanase genes in the root-lesion nematode Pratylenchus loosi, showing they resulted from gene duplication followed by sequence and gene structure diversification. The Pl-eng-2 gene was fully determined and found to be localized in the secretory esophageal glands of all life stages, while Pl-eng-3 and Pl-eng-4 were only partially sequenced, with loss of the linker domain and carbohydrate-binding domain during evolution.

Summary: Based on transcriptome data analysis of 38 liverworts, we re-evaluated the phylogeny of liverworts and provided evidence for ancient hybridizations and incomplete lineage sorting that shaped their deep evolutionary history. The study also found no evidence of whole-genome duplication events during the deep evolution of liverworts.

Summary: This study explored the immune diversity and specificity of invertebrates based on the lophotrochozoan RLRs, a major component in antiviral immune recognition. The analysis of genomes revealed that the N-terminal domains of lophotrochozoan RLRs showed the most striking diversity, evolved independently by domain grafting. Exon-intron structures were found to be prevalent in the domain grafting, resulting in the generation of non-canonical N-terminal domains. Transcriptomic studies showed that many non-canonical RLRs display immune-related expression patterns. Positive selection was observed in two RLRs, possibly a result of host defense selection pressure.

Summary: In this study, 30 DUF668 genes were identified in the soybean genome, distributed across fifteen chromosomes. Phylogenetic analysis classified these genes into three groups. Gene structure analysis showed that some of these genes lacked introns. Subcellular localization results indicated that GmDUF668 proteins were present in the nucleus, mitochondria, cytoplasm, and plasma membrane.

Summary: An analysis of sequence variation in a fragment of the STAYGREEN (SGR) locus in Pisum fulvum revealed 57 alleles, most of which differed in indel structure. The SGR sequence was found to be a more reliable indicator of accession identity than morphological characteristics. The study also showed that P. fulvum accessions can be divided into two allele groups.

Summary: SpliceAI is a widely used splicing prediction tool and we developed the SpliceAI-10k calculator (SAI-10k-calc) to extend its use for predicting various types of splicing aberrations with high accuracy. The SAI-10k-calc has 95% sensitivity and 96% specificity for predicting variants that impact splicing, and it performs well in predicting pseudoexon and partial intron retention. The automated amino acid sequence prediction feature allows for efficient identification of variants that may lead to mRNA nonsense-mediated decay or truncated proteins during translation.

Summary: Genome sequencing of the human parasite Schistosoma mansoni revealed a gene superfamily called micro-exon gene (meg) that encodes secreted MEG proteins. Through bioinformatics tools and phylogenetic analysis, this study identified conserved patterns in the sequences of highly variable MEG proteins and classified them into two subfamilies. It also proposed revisiting the common names and annotations of MEGs to avoid duplication and misunderstandings.

Summary: This study investigated the force regulation of incisor teeth treated with AMS during an unpredictable force control task. The results showed that AMS-treated incisors had lower peak force and peak force rate during the initial time-segment compared to the contralateral control teeth. However, there were no significant differences in holding force and coefficient of variability between the AMS-treated teeth and their controls during the later time-segment.

Summary: Clogging of sub entry nozzle is a recurring issue in continuous casting of low carbon aluminum deoxidized steel. A new modernized SMS shop faced a major problem of nozzle clogging, resulting in abrupt abortion of sequence casting. The high incidences of SEN clogging led to a loss of productivity. The study found that dendritic clusters of alumina originating from deoxidation and reoxidation of aluminum during secondary refining were the likely cause of SEN clogging. Optimization of the Ca treatment process was also required for successful continuous casting.
