Aecidium Jasminicola, a new pathogen for Jasminum sp. in Pakistan?

Jasmine (Jasminum) is a genus of shrubs and vines in the olive family (Oleaceae). It contains around 200 species native to tropical and warm temperate regions but their center of diversity is in South Asia and Southeast Asia. Jasmines are widely cultivated for the characteristic fragrance of their flowers as these are used commercially for making different products including tea. One of its species i.e. Jasminum officinale is also known as national flower of Pakistan. In present studies, plants of this economically important plant i.e. Jasminum were found infected with aecidial stage of some rust fungi. From morphological characterization it seems comparable with aecidial stages of previously reported rusts on same host. The fungus was found having similar infection pattern apparently like Aecidium jasminicola on Jasminum sp. in having rounded sori on abaxial side of leaf. Here molecular characterization of studied taxon reveals something different. In phylogenetic tree, studied taxon make clade with unpublished Macruropyxis sp. (JX036028). But aecia and uredinia of genus are unknown previously so it is difficult to identify this rust at specific level. Therefore present study reveals that the pathogen on Jasminum is an anamorphic stage of Macruropyxis sp., perhaps Aecidium Jasminicola. For identification of pathogen at specific level more sampling and data is required which is not yet available on any database.
