We evaluated the patterns of genetic variation of 16 Colchicum species, including 37 different genotypes, using RAPD marker and trnL–trnF chloroplast DNA sequence. A total of 861 polymorphic alleles through RAPDs showed a mean of 33.88 ± 3.80 alleles per primer, while mean major allele frequency was 0.067 ± 0.05. The sequence length of trnL–trnF ranged from 1022 bp to 1081 bp. The phylogenetic tree was constructed to understand the relationship between Colchicum species and the discrimination power of the nuclear and chloroplast genome for species. The results showed that trnL–trnF gene region grouped Colchicum species well in comparison with RAPD analysis. This data was also supported by haplotype network analysis, structure analysis and PCA (Principle Component Analysis). This study showed that there is a need for a characterization that contains more molecular and morphological methods to correctly distinguish Colchicum species.

A number of clinical studies have revealed that there is an association between major depression (MD) and gastroesophageal reflux disease (GERD). Both the diseases are shown to affect a large proportion of the global population. More advanced studies for understanding the comorbidity mechanism of these two diseases can shed light on developing new therapies of both diseases. To the best of our knowledge, there has not been any research work in the literature investigating the relationship between MD and GERD using their miRNA biomarkers. We adopt a phylogenetic analysis to analyze their miRNA biomarkers. From our analyzed results, the association between these two diseases can be explored through miRNA phylogeny. In addition to evidence from the phylogenetic analysis, we also demonstrate epidemiological evidence for the relationship between MD and GERD based on Taiwan biobank data.
