“…Translocations between wheat and barley chromosomes can be induced in the wheat-barley addition lines by a gametocidal gene (Shi and Endo, 1999). The present results provide a basis for breeding wheat cultivars that produce hordatines but possess no unfavorable parts of the barley chromosome.…”

Hordatines A and B, strong antifungal components in shoots of barley seedlings, were found to occur in a barley chromosome 2H addition line to wheat, but not in a wheat line carrying the long arm of chromosome 2H. These results showed that some genes that encode hordatine biosynthetic enzymes are located on the short arm of chromosome 2H. The total content of the hordatines was about six fold less than that in the parental barley, but was still at a concentration more than 20-fold higher than that required for inhibition of spore germination of pathogenic fungi.

“…When the Gc action is intense, gametophytes without the alien chromosome may experience severe chromosome breakage, and the gametes become sterile (Miller et al, 1982). This response results in exclusive transmission of the alien chromosome, such as in the common wheat cultivar 'Chinese Spring' (CS) with Gc chromosomes 3C from Aegilops triuncialis, 4S from A. longissima, and A. sharonensis (Finch et al, 1984;Endo, 1988;Shi and Endo, 1999). When the Gc action is mild, gametophytes without the alien chromosome display only slight chromosome damage.…”

“…The other is deletion mapping using deletions and translocations involving a dissected barley chromosome in common wheat (Serizawa et al, 2001). In the latter case, the structural changes of the barley chromosome were induced in a wheat-barley addition line using the gametocidal system (Shi and Endo, 1997, 1999. The same gametocidal system was applied successfully to the induction of terminal deletions in common wheat chromosomes (Endo, 1988(Endo, , 1990Endo and Gill, 1996).…”

We dissected barley chromosome 5H added to common wheat by a genetic method or the gametocidal system. Firstly, we induced chromosomal breaks in the offspring of a 5H addition line of common wheat carrying a gametocidal chromosome and cytologically screened for plants with structural chromosomal changes involving 5H, such as deletions and translocations. Secondly, we screened the progeny of such plants to establish common wheat lines carrying structurally changed chromosomes containing single segments of the dissected 5H. Using 23 representative 5H dissection lines, we physically mapped 97 barley EST markers assigned to 5H. The ESTs fell into 20 regions of 5H between the breakpoints of the 23 dissected segments, distributing rather evenly along the chromosome, with significantly higher frequency in the distal region of the long arm. The ESTs, in turn, allowed us to distinguish the breakpoints of dissected 5H segments. We demonstrated by PCR (polymerase chain reaction), as well as by in situ hybridization, that these dissected 5H segments were stably transmitted in the dissection lines. We discuss the usefulness of the 5H dissection lines for physical mapping of DNA markers. These 5H dissection lines are available from National BioResource Projects-Wheat, Japan.
