Genome De Novo Sequencing of Tissue Culture Plants

Without relying on reference genomes, Lifeasible can obtain the entire genome sequence information in the nucleus of tissue culture plant cells through next-generation sequencing technology. Based on this information, we can help you study the evolutionary relationships, genome evolution, and molecular evolution of the species. At the same time, we build a comprehensive research platform for the species to ensure the subsequent functional gene mining, analysis, and experimental validation needs.

What is Genome De Novo Sequencing?

Genome de novo sequencing, or genome de novo sequencing, refers to sequencing the whole genome sequence of a species without relying on known genome sequence information. The sequenced sequence is then spliced and assembled using bioinformatics to obtain a whole-genome sequence map of the species. The construction of the whole genome sequence atlas will comprehensively deepen the understanding of the evolutionary process of the origin of the species as well as its adaptation to a specific environment. It will play a great role in the future discovery of new genes in this species and the improvement of the species, and build an efficient platform for genomics research, providing DNA sequence information for subsequent gene mining and functional verification.
