A study published in GenomeBiology reveals the genetic underpinning for color variations in the Asian vine snake.
function in NCC differentiation and ultimately affects chromatophore development, especially that of iridophores.
In addition, we speculated that Asian vine snakes with other colors similarly follow this pattern of differences in iridophore morphology, and subtle differences in xanthophore and melanophore morphology may be the potential mechanisms for the formation of the other skin colors rather than green or yellow. Further researches are needed to verify the possibilities.
For the TEM experiments, two fresh skin samples per color morph from the Asian vine snake were collected. The samples were then cut into small pieces in fixative. The tissue blocks were transferred to an Eppendorf tube with fresh TEM fixative for further fixation, then washed using 0.1 M PB three times . The samples were dehydrated in an increasing ethanol series at room temperature, followed by two changes of acetone and transfer to resin for embedding.

NOMe-HiC: joint profiling of genetic variant, DNA methylation, chromatin accessibility, and 3D genome in the same DNA molecule - Genome BiologyCis-regulatory elements are coordinated to regulate the expression of their targeted genes. However, the joint measurement of cis-regulatory elements’ activities and their interactions in spatial proximity is limited by the current sequencing approaches. We describe a method, NOMe-HiC, which simultaneously captures single-nucleotide polymorphisms, DNA methylation, chromatin accessibility (GpC methyltransferase footprints), and chromosome conformation changes from the same DNA molecule, together with the transcriptome, in a single assay. NOMe-HiC shows high concordance with state-of-the-art mono-omic assays across different molecular measurements and reveals coordinated chromatin accessibility at distal genomic segments in spatial proximity and novel types of long-range allele-specific chromatin accessibility.
