Abstract

Abstract Gazania (L.) is one of wild ornamental plant which has special architectures. It is a small genus of 16 species, belonging to the family Asteraceae (Formerly: Compositae). It is low-growing perennial herb, grow in clumps and can also form dense carpets covering large areas. Gazania has multiple genera and species with mutli-petals colors. The chlorophyll pigmentation was measured in leaves and petals of these specimens which show high significant difference. Genomics is the study of genomes, and it can be used to conduct research on genome evolution, genomic variations, gene regulation, and important biological mechanisms using detailed genome sequence information. The diversity of ornamental plants, as well as the slow progress of genome research on ornamental plants for a long time. RAPD-PCR was applied in the present study to estimate the genetic variation in these samples which resulted in a total polymorphism percentage of 42.36%. This polymorphism percentage lead to the variation in essential physiological pathways in Gazania spp and reflected on the multivariate petals color.

生长在埃及北海岸的Gazania spp的异型性、生理和分子特征

摘要Gazania（L.）是一种具有特殊结构的野生观赏植物。它是菊科（原名：菊科）的一个小属，共有16种。它是生长缓慢的多年生草本植物，丛生，也可以形成覆盖大面积的密集地毯。Gazania有多个属和种，花瓣颜色各异。对叶片和花瓣的叶绿素色素含量进行了测定，结果表明，叶片和花瓣叶绿素色素含量差异显著。基因组学是对基因组的研究，它可以利用详细的基因组序列信息进行基因组进化、基因组变异、基因调控和重要生物学机制的研究。观赏植物的多样性，以及长期以来观赏植物基因组研究进展缓慢。本研究应用RAPD-PCR方法对这些样品的遗传变异进行了估计，总多态性百分比为42.36%。该多态性百分比导致了Gazania spp基本生理途径的变异，并反映在多变量花瓣颜色上。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
