3.2 GISH
GISH was carried out with the StY genome species (fromRoegneria ciliaris ) being used as a probe. GISH results showed
that R. yenchiana has 28 chromosomes, and all the chromosomes
displayed StY genome hybridization signal along their entire
chromosomal length (Figure 2E). Thus, the genomic constitution ofR. yenchiana is StStYY .
