概括
这项研究使用叶绿体基因组数据重新定义了罗萨科的马利部落,扩大了其范围,包括以前在马利科以外的属,并提出了新的子部落. 它还质疑几个属的区别,并将Sorbus属划分.
科学领域:
- 植物分类学 植物分类学
- 分子遗传学分子遗传学
- 罗萨ceae 家庭系统学 系统学
背景情况:
- 传统的四个子家族的罗莎属被一个三个子家族的系统所取代.
- 这就需要重新评估马里亚部落内属的界限,系统位置和族系.
- 以前的分类可能不准确地反映了Maleae.e.内部的进化关系.
研究的目的:
- 为了重新定义Rosaceae家族中的马利亚部落.
- 为了确定马利埃的精确系统位置.
- 用分子数据评估部落中所有公认的属的分类地位.
主要方法:
- 分析了来自罗莎属内的各种属的完整叶绿体基因组数据.
- 遗传学重建以推断进化关系.
- 对形态和分子数据进行比较分析,以评估通用状态.
主要成果:
- 马里亚部落被重新定义,包括马里亚科的带属和四个额外的属 (Gillenia,Kageneckia,Lindleya,Vauquelinia).
- 提出了四个子族:吉列尼纳,林德莱纳,沃格列尼纳和马利纳 (核心马利纳).
- 几个属 (Aria,Docyniopsis,Chamaemespilus,Mespilus) 缺乏独特的地位,Rhaphiolepis和Eriobotrya之间的关系需要进一步调查. 索布斯被发现是多种类的.
结论:
- 叶绿体基因组数据支持对马莱亚部落的更广泛的界限.

02:54Evolutionary Relationships through Genome Comparisons
5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

02:05Gene Evolution - Fast or Slow?
7.1K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

02:16Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
12.5K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

02:38Asexual Reproduction
31.2K
Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

02:19Export of Mitochondrial and Chloroplast Genes
3.7K
A eukaryotic cell can have up to three different types of genetic systems: nuclear, mitochondrial, and chloroplast. During evolution, organelles have exported many genes to the nucleus; this transfer is still ongoing in some plant species. Approximately 18% of the Arabidopsis thaliana nuclear genome is thought to be derived from the chloroplast’s cyanobacterial ancestor, and around 75% of the yeast genome derived from the mitochondria’s bacterial ancestor. This export has occurred...

01:23Phylogeny
44.0K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
