First report of Spartium witches’ broom disease in Spain

Plant Pathology, 2002
Symptoms of witches’ broom and decline were observed on Spanish broom ( Spartium junceum ) in Catalonia, Spain. The appearance of witches’ brooms, which developed from axillary buds on this woody perennial shrub, was followed by a drying of foliage. Affected plants eventually withered and died within a few years. A similar disease of S.

Molecular identification of Jujube witches'-broom phytoplasma (16SrV) associated with witches'-broom disease of Ziziphus oenoplia in India

Journal of Plant Pathology & Microbiology, 2020
Severe witches’-broom disease of Ziziphus oenoplia was observed with significant disease incidence in Bhopal, India, during 2019. Phytoplasma was detected from symptomatic leaf samples by polymerase chain reaction (PCR) using phytoplasma 16S rRNA gene specific primers which revealed positive amplification of expected size ~1.2 kb DNA band. The positive

Phenylpropanoid amides of serotonin accumulate in witches’ broom diseased bamboo

Phytochemistry, 2003
Aciculosporium take (Ascomycota; Clavicipitaceae), causes the witches' broom disease in bamboo, particularly Phyllostachys bambusoides. Since it was observed that endogenous indole-3-acetic acid is reduced in the twigs of the diseased bamboo, the symptoms (bushy appearance) may be induced by reduction in auxin levels. Furthermore, two indolic compounds

Status of alfalfa witches’ broom phytoplasma disease in Iran

Phytopathogenic Mollicutes, 2015
Alfalfa witches’ broom (AWB) is one of the most important and destructive diseases of alfalfa in Iran. Based on characteristic disease symptoms and direct and nested polymerase chain reactions, the status of AWB disease was evaluated in different growing areas of Iran. Restriction fragment length polymorphism was used to identify AWB disease associated

‘Candidatus Phytoplasma balanitae’ associated with witches’ broom disease of Balanites triflora

International Journal of Systematic and Evolutionary Microbiology, 2013
A phytoplasma was identified in naturally infected wild Balanites triflora plants exhibiting typical witches’ broom symptoms (Balanites witches’ broom: BltWB) in Myanmar. The 16S rRNA gene sequence revealed that BltWB phytoplasma had the highest similarity to that of ‘Candidatus Phytoplasma ziziphi’ and it was also closely related to that of ...
