宁夏枸杞与茄科其他植物线粒体基因组的比较与系统进化分析

本研究以宁夏枸杞(Lycium barbarum)的主栽品种‘宁杞1号’为参照,分别从基因构成、内含子分布、同源共线性、保守基因簇、重复序列,以及系统进化等方面与目前已报道的辣椒(Capsicum annuum)、茄子(Solanum melongena)、马铃薯(S.tuberosum)、番茄(S.lycopersicum)、天仙子(Hyoscyamus niger)和烟草(Nicotiana tabacum)等六种茄科(Solanaceae)植物的线粒体基因组进行比较分析,以进一步了解它们的线粒体基因组在结构组成上的异同和亲缘关系。结果表明,茄科不同植物的线粒体基因组大小差异较大,从413 881 bp(宁夏枸杞)到688 698 bp(马铃薯)不等,基因数量在61～71个,其中的蛋白质编码基因除在宁夏枸杞和辣椒中为单拷贝以外,在茄科其他植物中均出现不同程度的多拷贝现象。宁夏枸杞分别与茄子(16个)、马铃薯(16个)和天仙子(15个)共有较多数量的保守基因簇。通过线粒体基因组重复序列分析发现,宁夏枸杞与辣椒的重复序列数量接近,但宁夏枸杞中的简单重复序列(simple sequenc...

宁夏地区为害枸杞的泉蝇属一新种：双翅目：花蝇科

枸杞是我国名贵中药,主产宁夏,近十余年间不少省区广为引种,已成为一宗出口药材。此类植物是多种害虫的专食寄主,1987年8月于银川在枸杞育苗中发现一种蝇蛆潜食叶肉,庭院中的枸杞植株上也易见到为害;虽则大田栽培的枸杞园中尚未发现。这可能由于大田中对害虫常采取防治措施之故,可是如不加注意,今后有可能成为枸杞园重要害虫,值得警惕。我们对此蝇作了分类鉴定,为花蝇科泉蝇属Pegomya Rob.-Desv.的一新种,现记述如下:

An updated phylogeny of Deprea (Solanaceae) with a new species from Colombia: interspecific relationships,conservation assessment,and a key for Colombian species

Deprea is a neotropical genus that comprises 51 species. Recent work based on molecular data has explored its monophyly and interspecific relationships, but the relationships amongst Deprea species were not entirely elucidated. The inclusion of more accessions and molecular markers in phylogenetic analysis is likely to produce more supported hypotheses. Therefore, the main objective of this study was to perform a combined phylogenetic analysis of Deprea including seven new samples representing six species and one more DNA plastid marker than in previous studies. In that process, a new species of Deprea from Colombia was discovered and is described and illustrated here. Deprea teresitae Deanna & A. Orejuela, sp. nov. is morphologically similar to D. dilloniana and phylogenetically closely related to D. hawkesii and D. harlingiana. This new species is distinguished by the combination of short calyx lobes, non-mucronate anthers, long staminal filaments and corolla lobes, and elongated appressed fruiting calyx around a subglobose green berry. The new phylogenetic results are presented, including discussion on phylogenetic interspecific relationships, taxonomy, geographic distribution, and conservation status from D. teresitae. The synonymy of Deprea sylvarum subsp. novogranatensis under D. glabra is also proposed and an identification key to the 10 Deprea species distributed in Colombia is included.
