Zhang Chunyu's research group assembled a high-quality cruciferous Zhuge cai genome for the first time

Nanhu News Network News (correspondent Chen Peng Zhang Chunyu) Zhuge Cai, commonly known as "February Orchid", flowers in early spring and February and the flower color is blue-purple, which is a common seasonal ornamental plant and green cover plant in

On September 5, 2022, Zhang Chunyu's research group from the College of Plant Science and Technology of Huazhong Agricultural University and the National Oilseed Rape Engineering Technology Research Center of Huazhong Agricultural University published a paper entitled Genome Assembly of the Brassicaceae Diploid Orychophragmus violaceus Reveals Complex Whole Genome at Plant Commucations A research paper on Duplication and Evolution of Dihydroxy Fatty Acid Metabolism, which for the first time assembled high-quality cruciferous D.

Genomic structural characteristics and karyotype of the chromosome group of Zhuge Cai

The study found that the genome of Zhuge Cai has 24 chromosomes with obvious diploid characteristics

Diploid characteristics of Zhuge Cai's genome and comparison with Arabidopsis thaliana, Brassica A/C genome and Plate blue root genome and the evolutionary model of Zhuge Cai genome

Through transcriptome analysis of Zhuge cai seeds at different developmental stages, the researchers found that the genes expressed at the peak of dihydroxy fatty acid synthesis did not appear different from the new genes in cabbage type rape from functional annotation, including FAD2, FAE1 and other genes known to be involved in special fatty acid synthesis, and there were no obvious variations

In summary, genome assembly at the chromosome group level of Zhuge Cai reveals the evolutionary history of its genome different from that of brassica spp.

Transcriptome analysis of different developmental stages of Zhuge seeds identified candidate genes for special fatty acid synthesis

Associate Professor Huang Fan and Associate Professor Chen Peng, master's students of the College of Plant Science and Technology of Huazhong Agricultural University, are the co-first authors of the paper, Professor Zhang Chunyu of the National Oilseed Rape Engineering Technology Research Center of Huazhong Agricultural University, and Professor Edgar B.
