  • The global climate change and international trade have facilitated the movement of plants across borders, increasing the risk of introducing novel plant viruses in new territories. Ixora coccinea exhibited virus-like foliar symptoms, including mosaic and mild mottle. An Oxford Nanopore Technologies-based compact and portable MinION platform was used to identify the causal viral pathogen. The complete genome sequence of jasmine virus H (JaVH; 3867 nt, JaVH-CNU) was determined and found to share 88.4-90.3% nucleotide identity with that of Jasminum sambac JaVH isolate in China. Phylogenetic analysis based on the complete amino acid sequences of RNA-dependent RNA polymerase and coat protein revealed that JaVH-CNU was grouped separately with other JaVH isolates. This is the first report of a natural JaVH infection of I. coccinea. The application of rapid nanopore sequencing for plant virus identification was demonstrated and is expected to provide accurate and rapid diagnosis for virus surveillance.

  • 'JaGuiNaMu' is one of the Korean crude drugs used mainly to cure neuralgia, bone fracture, jaundice, and headache. With regard to the botanical origin of 'JaGuiNaMu', it has been considered to be Albizzia species of Leguminosae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JaGuiNaMu', the anatomical characteristics of the branch of Albizzia species growing wild in Korea, A. julibrissin and A. coreana were studied. As a result, it was clarified that 'JaGuiNaMu' was the branch of Albizzia julibrissin.
