Hibiscus plants, scientifically known as Hibiscus rosa–sinensis are grown in tropical and sub tropical areas. These are ornamental plants that are extensively used for hedges in gardens because of their dense growth and attractive flowers1, 2.
Many viral pathogens have become a serious threat for Hibiscus rosa-sinensis related industry but Hibiscus latent Fort Pierce virus (HLFPV) is a potential pathogenic agent which possess a single-stranded plus-sense RNA genome. HLFPV belongs to the genus Tobamovirus and family Virgaviridae and this viral organism infects Hibiscus plants all over the world including United States, Thailand, Japan, Brazil, Indonesia and Italy3, 4.
First and foremost infection of HLFPV in Hibiscus rosa-sinensis was confirmed for the first time by traditional electron microscopy, modern reverse transcription polymerase chain reaction and RNA-seq methods in China (HLFPV-Ch). The interaction between host plant Hibiscus rosa-sinensis and pathogen HLFPV is completely unknown which cause hindrance in managing the disease of hibiscus plants5.
Identification and characterization of target genes is paramount in order to understand the functions and implications of vsiRNAs in interaction with host. Summarily, vsiRNAs plays a central role due to their interactions with host by targeting their genes during HLFPV-Ch infection in hibiscus plants. This study ratified the HLFPV infection in China and for the first time results provides an insight into interaction between HLFPV and Hibiscus rosa-sinensis.
