查询词典 X-rays

Chromosome evolution: x= 11 occurred in most genera of Komarovieae through Selineae; other basic chromosome number originated multiple times independently in the subfamily Apioideae; For Pleurospermum and Pimpinella, the basic chromosome number of each coincide with their phylogenetic placement.

从性状演化图上看，整个芹亚科的染色体祖先状态可能为 x= 11或者 x= 6，而且亚科内的大多数类群均保持了 x= 11这一祖征；对于其它基数，一般在芹亚科内多次独立起源，构成各自的自征或者共有衍征；对于多系类群，如棱子芹属和茴芹属，染色体分析的结果很好的支持了他们各自的系统位置。
