title: Microdissection of plant chromosomes by argon-ion laser beam.
abstract: Rice and barley chromosomal samples were prepared both on a polyester membrane and on an ordinary glass slide and subjected to microdissection by an argon-ion laser. The intensity and the position of the laser beam were controlled by a microcomputer. The most suitable intensity to obtain chromosomal fragments was determined experimentally. As a result, specific regions of the centromere, satellite, short arm, or long arm, of the barley and rice chromosomes were dissected out from the chromosomal spreads. Chromosomal fragments were also successfully transferred from the sample into an Eppendorf tube.
