Circumscription and phylogeny of Saxifraga sect. Ciliatae: Evidence from nrDNA ITS sequences

The largest section of the genus Saxifraga (Saxifragaceae), sect. Ciliatae, consists of 175 morphologically diverse species. This section is mainly distributed in the Qinghai-Tibetan Plateau and adjacent regions of southwest China and more than 80% of the total number of species are endemic to this region. It remains unknown whether this section is monophyletic and up to now no study has been conducted on the infra-sectional phylogeny. In this study, ITS sequences of the nuclear ribosomal DNA were firstly determined for 33 species mainly from this section and related sections. We further downloaded the corresponding sequences of the same DNA region for the other 22 species of Saxifraga and Mitella from GenBank. All sequences were together used to construct the phy-logenetic trees. The main implications of the phylogenetic analyses include: (1) sect. Ciliatae, as traditionally defined, constitutes as a monophyletic clade and its sister group is a well supported clade that includes species from 8 sections such as sect. Porphyrion, sect. Saxifraga and sect. Mesogyne; (2) three morphological subsections, i.e., subsect. Gemmiparae, subsect. Hirculoideae and subsect. Rosulares were tentatively recovered despite the relatively low statistic bootstrap support for the last one; however, subsect. Flagellares and subsect. Hemi-sphaericae were not recognized as separate entities, and nested within subsect. Gemmiparae; (3) subsect. Hircu-loideae and subsect. Rosulares clustered together as sister subclades while subsect. Gemmiparae diverged early. In addition, our results suggest that the paired variation of ITS sequences in sect. Ciliatae is relatively low between the sampled species in spite of their diverse morphology. It is suggested that such a scenario may mirror rapid speciation in this section that probably trigged by the uplifts of the Qinghai-Tibetan Plateau and the extensive selection pressure under the alpine environments.     

Molecular phylogeny and genetic variation in the genus Lilium native to China based on the internal transcribed spacer sequences of nuclear ribosomal DNA

We present a comprehensive phylogeny derived from nuclear ribosomal DNA (nrDNA) for 214 samples representing 98 species and five varieties, including 44 species and five varieties native to China. Our collection of 25 species and five varieties (44 samples) covering all five sections of the genus (Comber) distributed in China also were included in the internal transcribed spacer (ITS) database. This study incorporates previous research with an emphasis on Chinese species, including the controversial subsection, Sinomartagon 5c Comber. In the phylogenetic tree obtained by maximum parsimony (PAUP) and maximum likelihood (RAxML) analyses, the samples were divided into four major groups. Our results suggest that the subsection (subsect.) 5c Comber should be classified into the true subsect. 5c and the section (sect.) Lophophorum. And the latter was divided into three subsections (subsect. Lophophorum I, subsect. Lophophorum II, and subsect. Lophophorum III). Based on molecular phylogenetic analysis and fluorescence in situ hybridization, we report that L. henryi and L. rosthornii are closely related, and we propose their classification into subsect. Leucolirion 6a. Our results support Comber’s subdivision of sect. Leucolirion, which was primarily based on bulb color. Chinese species were divided into five sections: sect. Martagon, sect. Archelirion, sect. Leucolirion, sect. Sinomartagon, and sect. Lophophorum. These findings contribute to our understanding of the phylogeny, origin, and classification of Lilium.

基于β-微管蛋白基因部分序列探讨灵芝属菌株的亲缘关系

PCR分别扩增了38个灵芝属菌株的β-微管蛋白基因片段,并对PCR产物进行序列测定,得到419bp的一段核苷酸系列.根据MEGA 2.1软件中的neighbour-joining methods对上述序列进行聚类分析,结果所有供试菌株被分成9个聚类组.中国栽培灵芝菌株分布于6个聚类组,其中树舌亚属、紫芝组的菌株各自聚成一组,灵芝组的菌株分成四组,但大部分灵芝组菌株均聚于同一组, 这表明树舌亚属、紫芝组和灵芝组间的遗传差异较大,灵芝组内虽然存在着一定的遗传差异,但总体上亲缘关系比较近,遗传多样性并不丰富.同时,序列分析的结果显示,β-tubulin基因序列在第三位密码子和内含子部位有高的碱基替换率,这些变异提供了丰富的系统发育信息,提示β-tubulin基因适合于灵芝属菌株的亲缘关系研究.     

Comparative Ecology of Rubus Species (Rosaceae) I. Ecological Distribution and Life History Characteristics of Three Species, R. palmatus var. coptophyllus, R. microphyllus and R. crataegifolius

Abstract The ecological distribution and life history characteristics of three Rubus species, i.e., R. palmatus Thunb. var. coptophyllus (A. Gray) O. Kuntze, R. microphyllus L.f. and R. crataegifolius Bunge were investigated, with particular emphasis on the seasonal growth cycles, modes of the alternation of aerial organs, and patterns of dry matter allocation, and these features were critically compared with one another. It was found that seasonal changes of aboveground biomass are strongly related to the modes of cane alternation, to underground branching producing stolons, and to their dry matter allocation patterns. The modes of cane alternation, underground branching and dry matter allocation patterns were very similar in R. microphyllus and R. crataegifolius , taking about five months from May to September. But R. palmatus var. coptophyllus showed much more gradual replacement of aerial organs, extending over seven months from May to December. These three Rubus species are often predominant in the early successional stages of pioneer communities which develop after cutting of forests in central Japan, and differentiations of the above-mentioned life history traits found in Rubus species seem to be related to the constraints inherent in their somewhat labile, changing environments, e.g., at the forest margin or clearings produced temporarily.
