Using fluorescence in situ hybridization, the authors investigated the homology between three plant species, maize (Zea mays L.) and tobacco (Nicotiana tabacum L.), maize and Arabidopsis thaliana (L.) Heynh. at cytogenetic level using two probes corresponding to functional disease resistance genes myb1 and NDR1 in Arabidopsis and tobacco respectively. The hybridization signals of the tested probes were detected in maize chromosomes 8 and 5 respectively, and the single location of each of the two probes showed only single copy of them in maize genome. The results provided a valuable insight into searching for genes associated with programmed cell death in plants using heterologous probe with comparative genetic approach. In addition, the improvements of FISH technique using heterologous probes were discussed. 展开更多
