Research

Our chromosome research was initiated around 1991 and has been progressing ever since. For example,Rice with twelve pairs of chromosomes (2n=24) and a 430-Mb genome, the smallest genome among all main cereal crops, have been identified. According to the recent plant chromosome researches, all chromosomes were well identified over the disadvantages of several chromosome size and quantitative rice chromosomal maps have been developed using chromosome image analysis system (CHIAS3). Moreover, agriculturally important genes have been detected using new direct DNA visualization methods with fluorescence in situ hybridization (FISH). This review describes the recent progress in molecular and digital cytogenetics using visualization from a historical perspective, highlighting the future prospects in plant chromosome science
