Abstract

The subgenus Orithyia in the genus Tulipa is considered one of the least studied. It includes the most eastern species of tulips. Previously, three species of tulips from this subgenus, T. heteropetala, T. uniflora, and T. mongolica were reported for the territory of Southern Siberia. The morphological analysis showed that studied plants, from populations previously reported in Southern Siberia under the name T. heteropetala, are large individuals of T. uniflora. There was a high level of morphological differences between all populations of T. uniflora and T. mongolica. Karyotype analysis showed that T. mongolica, T. uniflora, and T. siniangensis have similar karyotype structures. In T. heterophylla, in comparison with them, a lower level of intrachromosomal asymmetry was noted. Molecular genetic analysis confirms previous data and separates the subgenus Orithyia among other subgenera in the genus Tulipa. Molecular data confirmed taxonomic affiliation of specimens from the Zabaykalsky Territory (Russia) previously assigned by morphological characters to T. mongolica. Thus, it was confirmed that two species of tulips of the subgenus Orithyia, Tulipa uniflora and T. mongolica, grow in the studied area.

南西伯利亚有多少种属的郁金香(郁金香，百合科)?

郁金香属中的算法亚属被认为是研究最少的一种。它包括最东部的郁金香品种。此前，该亚属的三种郁金香(T. heteropetala)、T. uniflora和T. mongolica)在南西伯利亚地区被报道过。形态学分析表明，所研究的植物来自以前在西伯利亚南部报道过的以T. heteropetala命名的种群，是T. uniflora的大型个体。不同居群间的形态差异较大。核型分析表明，蒙古柽柳、单花柽柳和四娘柽柳具有相似的核型结构。在异茶树中，与它们相比，染色体内不对称程度较低。分子遗传分析证实了先前的数据，并将算法亚属从郁金香属的其他亚属中分离出来。分子数据证实了俄罗斯Zabaykalsky地区标本在分类上的亲缘关系。由此证实，在研究区生长有两种郁金香，即独花郁金香(Tulipa uniflora)和蒙古郁金香。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
