Corydalis yanhusuo comprosiming with a variety of morphology and diversity and is classed as the largest genus in the family Papaveraceae Chloroplast a kind of plastid which is ubiquitous in land plants algae and some protozoa It is an important organelle with independent genetic information in cells Because photosynthesis occurs in chloroplasts it becomes the energy source to promote the evolution of early life A comprehensive understanding of chloroplast genome and its role in biological evolution is of great significance for further study and full play of chloroplast function in the future thus The objectives of the project are sequencing the chloroplast gene of Corydalis yanhusuo analyzing the chloroplast assembly Complete gene structure annotation cpSSR analysis and RSCU analysis of chloroplast assembly results of all samples Complete the chloroplast genome map of all samples
