Construction of Identification System for Alien Chromatin in Crop Plant

In the previous decades, the expansion of genomic technologies has begun to revolutionize our ability to identify and measure genetic variation. The correct identification of alien chromatin involved in these gene transfers is crucial in a range of molecular and cytogenetic investigations. This paper presents the contribution of the sequential technique of C-banding, GISH and SSR marker on identification and detection of alien chromosomes, discusses the progress on identification of genetic variation, molecular and cytogenetic identification technologies, and prospects the significant construction of identification system for alien chromatin in crop plant.
