Desert rose witches’ broom disease associated with ‘Candidatus Phytoplasma aurantifolia’

Abstract: In March 2011, witches' brooms comprising many small shoots were observed on desert rose plants, Adenium obesum, in PyinOoLwin, Myanmar. The causal agent of the symptomatic leaves was diagnosed as a phytoplasma by polymerase chain reaction (PCR) analysis. Sequence analysis of the PCR product (1.8 kbp) showed the closest phylogenic relationships with members of the peanut witches' broom phytoplasma group. Additionally, phylogenetic analyses revealed the phytoplasma is a member of 'Candidatus Phytoplasma auranti… Show more

“…Diseases of ornamentals crops may be caused by pathogens such as bacteria, fungi, viruses and phytoplasmas. In the desert rose, several pathogens have already been described causing damage such as Cucumber mosaic virus in Florida (Baker et al., 2003) and in Taiwan (Chen et al., 2012), Tomato spotted wilt virus in Florida (Adkins & Baker, 2005), the fungus Nigrospora sphaerica in Brazil (Jesus et al., 2020), Candidatus Phytoplasma asteris in India (Raj et al., 2007), and Candidatus Phytoplasma aurantifolia in Myanmar (Win et al., 2012). The diseases of ornamental plants, in general, can represent a limiting factor in their cultivation and commercialization, thus being able to cause enormous economic losses for the farmers.…”

“… Almehdar et al (2012) screened 40 medicinal plants used in the folk medicine of Saudi Arabia for their cytotoxic activity against breast cancer (MCF7), hepatocellular carcinoma (HepG2), HFB4 (normal melanocytes), and cervix cancer (HeLa) cell lines. The methanol extract of Hypoestes forskaolii was the most active against HFB4 with IC 50 value 4.18 μg/mL, while the methanol extract of Adenium obesum which is native to south and east of Africa and found wildly in Oman, Saudi Arabia, and Yemen ( Win et al, 2012 ) was the most cytotoxic extract against HeLa cells with an IC 50 value 6.9 μg/mL. The methanol extract of Capparis tomentosa Lam.…”
