Genome-Wide Identification of SSR and InDel Markers and Experimental Validation of SSR Markers for Distinguishing Cold-Tolerant and Cold-Sensitive Lily Cultivars.

In this study, whole-genome resequencing was performed on the cold-tolerant variety ND-6 and the cold-sensitive variety 'Sorbonne'. After evaluation, the Lilium davidii var. unicolor reference genome was selected to analyze SSR distribution characteristics. Whole-genome InDel identification and comparative analysis were conducted for the two varieties, yielding 34,812,909 and 24,497,857 InDels, respectively. Short InDels were predominant, with deletions slightly outnumbering insertions, mostly located in intergenic regions. Twenty pairs of SSR primers were screened and synthesized. Among them, 10 pairs amplified clearly, with a polymorphism rate of 82.6%, effectively distinguishing the two cultivars examined in this study. This study provides systematic data and a reliable marker resource for the analysis of lily genomic variation, laying a foundation for the identification of cold-tolerant germplasm; validation across additional cultivars and individuals will be required to extend their utility to broader germplasm.

Genomic loci and molecular genetic mechanisms for hidradenitis suppurativa.

BACKGROUND: Hidradenitis suppurativa (HS) is a common, chronic and debilitating inflammatory disease that most commonly affects intertriginous skin. Despite its high heritability, the genetic underpinnings of HS remain poorly understood. OBJECTIVES: To identify genetic signals associated with HS, determine genetic relationships with other diseases and investigate potential molecular genetic mechanisms. METHODS: We performed a genome-wide association meta-analysis of six studies, totalling 4540 patients with HS and > 1 million control participants, and identified genetic correlations with other common diseases. We integrated the HS data with expression quantitative trait loci from 10 trait-relevant tissues, epigenomic and transcriptomic data from human scalp, differential expression data from HS lesions vs. adjacent skin and mesenchymal Hi-C chromatin looping data. To identify functional noncoding variants, we performed transcriptional reporter assays for signals near KLF5 and SOX9. RESULTS: We identified 11 significant HS signals across 7 loci: 4 corresponded to previously reported associations, 4 represented novel signals within known loci and 3 were signals in newly implicated loci. We identified significant genetic correlations between HS and other inflammatory conditions, particularly inflammatory bowel disease, rheumatoid arthritis, type 2 diabetes mellitus and asthma. We prioritized candidate genes for the 11 signals. The risk allele at KLF5 exhibited 10-fold greater transcriptional activity than the nonrisk allele, while risk alleles at SOX9 showed significantly reduced transcriptional activity. CONCLUSIONS: Our results provide insights into potential genetic mechanisms underlying HS and suggest potential therapeutic targets for this challenging condition.

Landscape and m6A post-transcriptional regulation of soybean proteome.

The soybean is a critical source of vegetable protein, but its proteome remains undercharacterized. Here, we quantify 12,855 proteins across 14 soybean organs using 4D data-independent acquisition mass spectrometry (4D-DIA-MS), creating the most extensive soybean proteome dataset to date. Organ-specific protein expression and co-expression analyses highlight functional specificity with significant differences in protein-transcript abundance across organs. We also map N6-methyladenosine (m6A) modifications, identifying their key role in post-transcriptional protein regulation. Integrative analysis of the proteome and m6A methylome identifies a novel regulator in m6A methylation. This comprehensive proteomic and m6A landscape advances our understanding of soybean biology and provides a valuable resource for crop improvement.
