Newswise — A research team successfully sequenced and assembled the genome of the purple finger lemon variety 'YaoJi', revealing a genome size of 314.63 Mb across nine chromosomes. The study identified 21,154 protein-coding genes and significant gene expression differences linked to rind color variations.
This research presents a high-quality genome sequence, shedding light on the evolutionary history of finger lemons and facilitating future functional gene mining. These findings hold the potential for enhancing variety selection and improving the economic and medicinal value of finger lemons. Finger lemon ( Citrus australasica ), valued for its unique flavor and medicinal properties, has an incomplete genome data, especially for the purple variety 'YaoJi'.
Current research has focused on its chemical composition, but the genetic basis of rind color variation remains unexplored. The lack of high-quality genome data hampers understanding of its evolution. A study (DOI: 10.
48130/tp-0024-0021) published in Tropical Plants on 21 May 2024, aims to sequence and analyze the 'YaoJi' genome using nanopore technology, investigating the molecular mechanisms underlying rind color differences to inform future selection and cultivation strategies. In this study, the genome of finger lemon 'YaoJi' was assembled using a whole genome birdshot (WGS) strategy and second-generation sequencing technology. A second-generation small fragment DNA library was constructed, yielding 35.
95 Gb of filte.
