Sicana odorifera also known as cassabanana, sikana or musk cucumber, is naturally grown from Mexico to Brazil and the west Indies. Fruits are edible, the pulp and the seeds have a medicinal use, and the whole plant is used as an ornamental. In the State of Rio de Janeiro, Brazil, naturally diseased sikana plants were observed, for the first time, with witches’ broom growths and other symptoms c...

In the present study 14 bacterial strains were isolated from root nodule of Crotolaria junceae L. from 4 different sites of Assam. The isolates were investigated for their morphological characteristics. Three different confirmatory tests were performed with the isolates. The isolates were also investigated for their biochemical characteristics and compared with biochemical characteristics of re...

The quantum density of states of the Henon-Heiles potential displays a pronounced beating pattern. This has been explained by the interference of three isolated classical periodic orbits with nearby actions and periods. A singular magnetic flux line, passing through the origin, drastically alters the beats even though the classical Lagrangian equations of motion remain unchanged. Some of the ch...

"Candidatus Phytoplasma aurantifolia" is associated with witches' broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches' broom symptoms in some locations in Oman and the UAE. This study investigated whether phytoplasma strains belonging to "Ca. P. aurantifolia" (based on the 16S rRNA g...

ABSTRACT The witches'-broom disease, caused by the basidiomycete Crinipellis perniciosa, is the most limiting factor for cacao cultivation in Brazil. Trichoderma stromaticum is a mycoparasite of the witches'-broom pathogen of cacao that is currently being applied in the field to manage the disease in Bahia State, Brazil. In this work, molecular and traditional methods were used to study the gen...

Witches' broom of lime is a disease caused by Candidatus Phytoplasma aurantifolia, which represents the most significant global threat to the production of lime trees (Citrus aurantifolia). Conventional disease management strategies have shown little success, and new approaches based on genetic engineering need to be considered. The expression of recombinant antibodies and fragments thereof in ...

One of the most important themes in agricultural science is the identification of virulence factors involved in plant disease. Here, we show that a single virulence factor, tengu-su inducer (TENGU), induces witches' broom and dwarfism and is a small secreted protein of the plant-pathogenic bacterium, phytoplasma. When tengu was expressed in Nicotiana benthamiana plants, these plants showed symp...

Phytoplasmas have the smallest genome among bacteria and lack many essential genes required for biosynthetic and metabolic functions, making them unculturable, phloem-limited plant pathogens. In this study, we observed that transgenic Arabidopsis (Arabidopsis thaliana) expressing the secreted Aster Yellows phytoplasma strain Witches' Broom protein11 shows an altered root architecture, similarly...

BACKGROUND The witches' broom disease is a plague caused by Moniliophthora perniciosa in the Theobroma cacao, which has been reducing the cocoa production since 1989. This issue motivated a genome project that has showing several new molecular targets, which can be developed inhibitors in order to control the plague. Among the molecular targets obtained, the UDP-N-acetylglucosamine pyrophosphor...
