Journal Article Witches' broom disease of lime caused by '<em>Candidatus</em> Phytoplasma <em>aurantifolia'</em> is considered as one of the most destructive disease of Mexican lime in southern Iran, Oman, and the United Arab Emirates. The causative phytoplasma is vectored by a leafhopper, <em>Hishimonus phycitis </em>(Distant, 1908). Six ISSR markers and mitochondorial Cytochrome <em>c</em> Oxidase I (COI) gene were used to unveil genetic variation of the leafhopper populations from thirteen different regions of Iran. Analysis of ISSR markers revealed that Forg (Fars) and Qale'e Qazi (Hormozgan) significantly diverged from the other populations. However, the COI sequences were highly conserved among all populations and resided all the populations in a single clade. Mantel test exhibited no correlation between genetic and geographical distances. Our results demonstrated genetic differentiations among the <em>H. phycitis</em> populations, which might have been induced by ecological or geographical isolation and may affect the vectoring capability of this insect.<br> https://jast.modares.ac.ir/article_16199_5061e9e272546d556c59c55e2853d22e.pdf
