Abstract: Genome graphs can represent genetic variation and sequence uncertainty. Aligning sequences to genome graphs is key to many applications, including error correction, genome assembly, and genotyping of variants in a pangenome graph.
Genetic mapping uses the Mendelian principles of segregation and recombination to determine the relative proximity of DNA markers along the chromosomes of an organism. ... Genetic markers are important developments in the field of plant breeding.
The CGView (Circular Genome Viewer) software family is a popular collection of tools for generating genome maps for bacteria, organelles and viruses. In this review, we describe the capabilities of the original CGView program along with those of subsequent companion applications, including the CGView Server and the CGView Comparison Tool. We also discuss GView, a graphical user interface-enabled rewrite of CGView, and the GView Server, which offers several integrated analyses for identifying shared or unique genome regions relative to a comparison genomes. In this work we present and conclude with some remarks about our current development efforts related to CGView aimed at adding new functionality while increasing ease of use.

Abstract: The aim of this study was to examine the effects of extracting and preserving conditions on the betacyanin pigment from the peel of white dragon fruit. The investigated factors for the extraction process include: the ratio of solvent and material, the extraction temperature, the time of extraction, the number of extraction and color stability of the extract under different storage conditions. The results showed that the highest betacyanin content was obtained by double extraction with distilled water at the extraction temperature (40oC), the time of extraction (8 hours) and the ratio of solvent and material is 20/1 (v/w). After 7 days of storage at 4oC in the dark, the color of the extract was almost unchanged. However, the crude extract lost red color rapidly when stored at room temperature (RT) under natural light. Betacyanin has potential applications as a natural colorant for foods, medicines and cosmetics.
