The molecular characterization of maize B chromosome specific AFLPs

Cell Research 2002年第1期12卷 63-68页

作者： ZHONG XIA QI, Hui ZENG, xiu LAN li, cheng BIN CHEN, WEN QIN SONG, RUI YANG CHEN The College of life Sciences, Nankai University, Tianjin 300071, China The College of life Sciences Nankai University Tianjin China

The origin and evolution of B chromosomes could be explained by the specific DNA sequence on them. But the specific sequences known were quite limited. To investigate maize B chromosome sqicific DNA sequeces, maize genomes with and without B chromosomes were analyzed by AFLP. Only 5 markers were found specific to genomes with B chromosomes among about 2000 AFLP markers. Southern hybridization and sequence analysis revealed that only the sequence of M8-2D was a B chromosome specific sequence. This sequence contained the telomeric repeat unit AGGGTTT conserved in plant chromosome telomeres. In addition, the sequence of M8-2D shared low homology to clones from maize chromosome 4 centromere as well. M8-2D were localized to B chromosome centrorneric and telomeric regions.
