To date, there have been no reports of Dalmatian toadflax serving as a host for cucumber mosaic virus (CMV). Infestations of Dalmatian toadflax may serve as a reservoir of CMV, thereby facilitating aphid transmission of CMV to both agricultural crops and native plants. The goal of this study was to determine whether Dalmatian toadflax is a host for CMV. Dalmatian toadflax seedlings were randoml...

In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...
