Abstract

Chamomile is an annual flower having medicinal, therapeutic, consumption, cosmetic uses since a long time. It is native to southern and eastern Europe and has been grown in many other countries. Here, we identify a novel Deltapartitivirus, chamaemelum cryptic virus (CCV) through publicly available RNA-seq data of chamomile. CCV contains two genomic RNA segments i.e. RNA1 (BK068401) and RNA2 (BK068402). CCV RNA1 (1597 nt) encoded for an RNA dependent RNA polymerase (RdRp) protein (481 aa) while CCV RNA2 (1682 nt) encoded for a coat protein (CP) (478 aa). Homology and phylogenetic analysis of CCV genome showed relatedness with beet cryptic virus 3 (YP009665971) and vitis cryptic virus (BCS51498). Based on the sequence demarcation criteria, CCV represents a newly discovered species within the Deltapartitivirus genus of the Partitiviridae family, associated with a new host i.e. chamomile.
