Based on an improved C-banding technique, the C-banding patterns of all 11 diploid Aegilops species were described and compared. All diploid species exhibit characteristically different patterns which enable the chromosomes of any complement to be identified individually. These patterns confirm existing genome symbols and provide further evidence for the suggested changes in genome symbols of Ae. umbellulata and Ae. sharonensis, U and S(sh) respectively. Furthermore, Ae. uniaristata should be given a separate symbol, probably N. Aegilops speltoides and Ae. sharonensis could be possible donors to the B genome of wheat. Interspecific divergence in these diploid species has been accompanied by either amplification or deletion as well as massive repatterning of heterochromatin from the centromere to the telomere.
基于改良的 C-带技术,描述并比较了所有 11 种二倍体节节麦种的 C-带模式。所有二倍体种都表现出明显不同的模式,使任何染色体组都能被单独识别。这些模式证实了现有的基因组符号,并为 Ae.umbellulata 和 Ae.sharonensis 中 U 和 S(sh) 基因组符号的建议变化提供了进一步的证据。此外,Ae.uniaristata 应该有一个单独的符号,可能 N. Aegilops speltoides 和 Ae.sharonensis 可能是小麦 B 基因组的供体。这些二倍体种之间的种间差异伴随着着从着丝粒到端粒的异染色质的扩增、缺失以及大规模重排。
