Heteromorphic, physiological and molecular characteristics of Gazania spp grow in North Coast of Egypt

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.
