Article Abstract
Platostoma palustre (Blume) A.J.Paton is an annual herbaceous persistent plant of the Labiatae family. However, there is a lack of genomic data for this plant, which severely restricts its genetic improvement. In this study, we performed genome survey sequencing of P. palustre and developed simple sequence repeat (SSR) markers based on the resulting sequence. K-mer analysis revealed that the assembled genome size was approximately 1.21 Gb. A total of 15,498 SSR motifs were identified and characterized in this study; among them, dinucleotide, and hexanucleotide repeats had the highest and lowest, respectively. Among the dinucleotide repeat motifs, AT/TA repeat motifs were the most abundant, and GC/CG repeat motifs were rather rare, accounting for 44.28% and 0.63%, respectively. Genetic similarity coefficient analysis by the UPMGA methods clustered 12 clones, of P. palustre and related species into two subgroups. These results provide helpful information for further research on P. palustre resources and variety improvements.

Clustered regularly interspaced palindromic repeats (CRISPR)-associated transposons (CAST) consist of an integration between certain class 1 or class 2 CRISPR-Cas systems and Tn7-like transposons. Class 2 type V-K CAST systems are restricted to cyanobacteria. Here, we identified a unique subgroup of type V-K systems through phylogenetic analysis, classified as V-K_V2.

Introduction: Galectin-9 is a β-galactoside-binding lectin that functions as a critical pattern recognition receptor (PRR) in the host immune system, initiating immune defense responses by recognizing and binding to pathogen-associated molecular patterns (PAMPs) on the surface of microorganisms. In this study, we identified and characterized a novel galectin-9 cDNA, designated CcGal-9, from Yellow River carp ().
Methods: The full-length CcGal-9 cDNA was cloned and sequenced, and its structural features were analyzed.

TLR8 and TLR9 are innate immune receptors belonging to the TLR family that are essential for viral recognition and early immune activation. Their dysfunction is linked to increased susceptibility to infections. TLR8 detects viral single- and double-stranded RNA, while TLR9 recognizes viral DNA molecules with CpG motifs.

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease characterized by mislocalization and aggregation of proteins in motor neurons. Ataxin-2 (ATXN2), an RNA-binding protein harboring 22-polyglutamine (polyQ) repeats, is a risk factor for ALS, when its polyQ repeats are expanded to 27-33 repeats. However, the physiological function of ATXN2 beyond its role in RNA regulation, and how polyQ expansion in ATXN2 increases risk for ALS, remain unclear.
