Abstract:

Cytogenetics was established based on the “Chromosome theory of inheritance”, proposed by Boveri and Sutton and evidenced by Morgan’s lab in early stage of the 20 th centrary. With rapid development of related research areas, especially molecular genetics, cytogenetics developed from traditional into a new era, molecular cytogenetics in late 1960s. Featured by an established technique named DNA in situ hybridization (ISH), molecular cytogenetics has been applied in various research areas. ISH provids vivid and straightforward figures showing the virtual presence of DNA, RNA or proteins. In combination with genomics and cell biology tools, ISH and derived techniques have been widely used in studies of the origin, evolution, domestication of human, animal and plant, as well as wide hybridization and chromosome engineering. The physical location and order of DNA sequences revealed by ISH enables the detection of chromosomal re-arrangments among related species and gaps of assembled genome sequences. In addition, ISH using RNA or protein probes can reveal the location and quantification of transcripted RNA or translated protein. Since the 1970s, scientists from universities or institutes belonging to the Jiangsu Society of Genetics have initiated cytogenetics researches using various plant species. In recent years, research platforms for molecular cytogenetics have also been well established in Nanjing Agricultural University, Yangzhou University, Nanjing Forestry University, Jiangsu Xuhuai Academy of Agricultural Sciences, and Jiangsu Normal University. The application of molecular cytogenetics in plant evolution, wide hybridization, chromosome engineering, chromosome biology, genomics has been successful. Significant progresses have been achieved, both in basic and applied researches. In this paper, we will review main research progresses of plant cytogenetics in Jiangsu province, and discuss the potential development of this research area.
