用水稻微卫星引物进行竹子分子系统学研究初探

PRELIMINARY STUDY ON MOLECULAR SYSTEMATICS OF BAMBOO BY SSR PRIMERS DERIVED FROM RICE

竹子和水稻在进化上有较近的亲缘关系 ,本文利用水稻的微卫星引物对竹子的分子系统学进行了初步研究。与传统的分类结果不同 ,研究发现巴山木竹属是与青篱竹属相关属分化较大的 1个竹种 ,同时也证实了巴山木竹属作为 1个单独的属是成立的。研究也明确了茶秆竹的分类学位置。本研究从 1个不同的层面对青篱竹属相关属及属下一些竹种的关系提供了 1个新的研究结果 ,为利用现代分子生物学技术对广义青篱竹属的系统学研究提供了 1个借鉴。同时本研究对开展竹子的分子生物学研究提供了

The taxonomic disorder in genus of Arundinaria Michaux is the disputing focus in the taxonomic study of leptomorph bamboos.For a long time,there is no suitable strategy to study the genus of Arundinaria and the related genera.In this paper we presented a method of using the SSR primers of rice to settle the problem according to the near phylogenic relationship between bamboo and rice.Differing to the traditional taxonomy,it showed that there was a large differentiation beween genus of Bashania Keng f.et Yi and related genera of Arundinaria Michaux,and proved that Bashania Keng f.was regarded as a distinct and isolated genus.The taxonomic problem of Arundinaria amabilis (McClure) Keng f. was also discussed in this paper.It provided a new result for the relationship of the genus of bamboo related to Arundinaria Michaux from different aspects comparing to the traditional study.It also offered a reference for the phylogenic study of Arundinaria Michaux in a broad sense by modern molecular biotechnique.This study put forth new thought and strategy to carry out molecular biology research in bamboo.
