High-resolution mapping of secalin-1 (Sec-1) locus has been performed by fluorescence in situ hybridization to extended DNA fibers of rye (Secale cereale, 2n = 14), employing DNA probes of lambda phage clones containing the omega-secalin gene. The fluorescent signals to rye extended DNA fibers revealed continuous strings of 45 microm, corresponding to the size of 147 kb DNA. To determine the copy number of Sec-1 locus on DNA fibers, a 1.2-kb fragment including the entire coding region of the omega-secalin gene and a 1.0-kb fragment of the promoter region were amplified by PCR as probes for another fiber FISH. The physical position of these sequences was visualized as alternating fluorescent spots by multicolor in situ hybridization. Alternating signals of two DNA probes reflected the tandem repeated organization of the Sec-1 locus having 15 copies of the gene. The present findings based on fiber FISH analysis support the contention that the omega-secalin genes are arranged in a head-to-tail fashion separated by 8 kb of spacer sequences with a total length of 145 kb.
