Zhu Shuijin's team from the College of Agriculture published a paper in Plant Communications to analyze the evolution of the whole genome of Bick's cotton and the formation mechanism of pigment glands and gossypol

On August 10, 2022, Zhu Shuijin's team from the College of Agriculture published a research paper entitled "A reference-grade genome assembly for Gossypium bickii and insights into its genome evolution and formation of pigment gland and gossypol" in the journal Plant Communications

Cotton is an important economic crop, and cottonseed is rich in oil and protein

In this study, using Illumina sequencing, PacBio sequencing and Hi-C assisted assembly technology, the whole genome sequencing and assembly of B.

The study found that the Bick's cotton genome is the closest relative to Gossypium australe (G ₂ ), which is the same as the G genome, followed by the A genome, and the farthest from the D genome
