Recent development of image analysis methods in plant chromosome research.

Image analysis methods have provided effective tools in chromosome research along with the development both in computer software and hardware. A chromosome image analyzing system, CHIAS, for plant chromosomes was developed in 1985 and was subsequently revised so that with CHIAS3 one can take advantage of Internet use for downloading the program. In this review, the recent developments of imaging methods in plant chromosome research for automating chromosome identification, constructing a map of a pachytene chromosome, and patterning of interphase nuclei are described.
