Fasciation in Crassula argentea: molecular identification of phytoplasmas and associated antioxidative capacity

Phytoplasma-induced biochemical and genetic variations in Crassula argentea

“…The studied plants were growing near to Petunia hybrid beds that were infected by phytoplasma. About 140 plants had fasciation symptoms from 500 Crassula plants with the percentage 28% (Dewir et al 2016). All analyses in this study were carried out in Physiology and Breeding of Horticultural Crops Laboratory, Kafrelsheikh University during two years (2017 and 2018).…”

“…The morphological symptoms of phytoplasma infection in Crassula argentea have been described as fasciation of leaves (Dewir et al, 2016). Infected plants by phytoplasma had clearly visible morphological differences when compared with normal plants.…”

“…Collectors and horticulturists are researching on fasciated plantas real living sculptures. Therefore, the prices of phytoplasma-infected cacti can reach ten folds over non-infected species (Dewir et al 2016).…”

“…In the previous report, identified fasciation phytoplasmas in Crassula argentea (The accession number of phytoplasma in Gene Bank was HG421074). Genetic analysis potted the fasciation phytoplasma in the group of 16SrII-D (Dewir et al 2016). The aims of this study were the determination of the changes in biochemical and water content of normal and abnormal plants, also, using RAPD molecular marker for the detection of genetic variations in phytoplasma infected plants.…”
