Developmental Genomics of Ascidians delves into the unique characteristics that make ascidians invaluable for studying developmental genomics. Authored by Dr. Noriyuki Satoh, this comprehensive work was first published on January 28, 2014, by Wiley-Blackwell. Spanning 216 pages, the book highlights the simplicity and lack of redundancy in the regulatory genes of ascidians, particularly focusing on Ciona species. Emphasizing single-cell level analyses, it showcases how these organisms serve as model systems for exploring developmental genomics. The text underscores the advantages of using ascidians in this rapidly advancing field, making it an essential resource for researchers and students interested in understanding the complexities of gene regulation during development.
