Morphological and molecular diagnosis of Cuscuta sp parasitizing Solanaceae plants in the middle of Iraqi provinces
Journal Title: Journal of Research in Ecology - Year 2018, Vol 6, Issue 2
Abstract
The genus Cuscuta is represented with 14 species distributed in all the regions of Iraq. Most species belonging to this genus cause a major problem in the fields of many agricultural crops including Solanaceae members which are severely affected by these parasitic plants. Geographical distribution, host-range and phenotypic diagnosis supported by molecular diagnosis as well as host-parasitism (histopathology) studies were conducted to detect the parasitic species of Cuscuta on the Solanaceae, and the most widespread. We aimed to create a database facility for providing an Integrated Weed Management (IWM) program in order to increase plant health in Solanaceae cultivation fields in Iraq. The average infection ratio of Cuscuta sp on this family members was as high as 70.39 % in the provinces of Najaf, Karbala and Babylon. 10 Cuscuta races were registered as new races nationally and then submitted to NCBI database. C. pentagona and C. australis were recorded for the first time in Iraq in the presented study. However, C. campestris was found to be most predominant over other species of Solanaceae. In this study we showed for the first time the ability of C. campestris to parasitize on eggplant fruits, which have been proved anatomically in addition to some other traits
