Title: Genetic diversity and genome sequencing of some potato virus Y isolates from Egypt
Biography: Faiza A Fattouh
Potato is the second most important food crop in Egypt in terms of yield and cash value. Virus infection is a major factor which aff ects production and tuber quality. Detection of several different potato viruses has been reported in some studies; yet, few limited studies addressed the genetic characterization of such viruses. PVY is a major virus affecting potato and is of worldwide distribution. Th e aim of this work is to elucidate more information on PVY genetic diversity in Egypt. Following several surveys for the detection of major viruses affecting potato in different geographic governorates, some PVY isolates were subjected to molecular characterization by means of immunocapture RT-PCR and also full genome sequencing. Multiple recombinant types of PVY were distinguished. At least 3 recombinant strains previously associated with potato tuber necrotic ringspot disease (PTNRD), including a novel recombinant were identified. These findings suggest the presence of PTNRD-inducing virus strains infecting potato.
