Article Abstract
Bergenia purpurascens is an important medicinal, edible and ornamental plant. The lack of omics information hinders the study of its metabolic pathways and related genes. In order to investigate candidate genes and pathways involved in secondary metabolism in B. purpurascens, roots, stems and leaves of B. purpurascens were subjected to metabolomic and transcriptomic analyses in this study. A total of 351 differentially accumulated secondary metabolites were identified. We identified 120 candidate genes involved in phenylpropanoid and flavonoid biosynthesis pathway, from which 29 key candidate genes were obtained by WGCNA. Five UDP-Glycosyltransferases and four O-methyltransferases were suggested to be the candidate enzymes involved in synthetic pathway from gallic acid to bergenin by correlation analysis between transcriptional and metabolic levels and phylogenetic analysis. This study provides data resources and new insights for further studies on the biosynthesis of major active components in B. purpurascens.

Background: There is a higher prevalence of heart rate corrected QT (QTc) prolongation in patients with diabetes and metabolic syndrome. QT interval genome-wide association studies have identified candidate genes for cardiac energy metabolism, and experimental studies suggest that polyunsaturated fatty acids have direct effects on ion channel function. Despite this, there has been limited study of metabolite concentration relationships with QT intervals.

Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma with a poor prognosis and short survival rates. It is classified as a large B-cell lymphoma subtype, but carries a plasmacytic immunophenotype. Therefore, PBL has pathogenetic overlaps with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS) and plasma cell neoplasms (PCNs).

Essential tremor (ET) is a common neurological disease that is characterized by 4-12 Hz kinetic tremors of the upper limbs and high genetic heterogeneity. Although numerous candidate genes and loci have been reported, the etiology of ET remains unclear. A novel ET-related gene was initially identified in a five-generation family via whole-exome sequencing, and other variants were identified in 772 familial ET probands and 640 sporadic individuals via whole-genome sequencing.

The genetic basis of early-stage salt tolerance in alfalfa (Medicago sativa L.), a key factor limiting its productivity, remains poorly understand. To dissect this complex trait, we integrate genome-wide association study (GWAS) and transcriptomics (RNA-seq) from 176 accessions within a machine learning based genomic prediction framework.

The transcription factor Six1 and its co-activator Eya1 play central and varied roles during the development of sensory neurons derived from the cranial placodes in vertebrates. Previous studies suggested that these proteins promote both the maintenance of proliferative neuronal progenitors and neuronal differentiation. Context-specific interactions of Six1 and/or Eya1 with different cofactors are likely to contribute to the activation of distinct target genes during different stages of placodal neurogenesis.
