MBCAST: A Forecast Model for Marssonina Blotch of Apple in Korea.

A disease forecast model for Marssonina blotch of apple was developed based on field observations on airborne spore catches, weather conditions, and disease incidence in 2013 and 2015. The model consisted of the airborne spore model (ASM) and the daily infection rate model (IRM). It was found that more than 80% of airborne spore catches for the experiment period was made during the spore liberation period (SLP), which is the period of days of a rain event plus the following 2 days.

Molecular detection and characterization of a divergent isolate of Plantago asiatica mosaic virus in .

Four samples of showing mottle or mottled yellowing symptoms were collected and three of them were confirmed to be infected with Plantago asiatica mosaic virus (PlAMV) by Illumina HiSeq 2500 paired-end RNA sequencing. Consequently, the complete genomic sequence of a Korean isolate of PlAMV (PlAMV isolate Gunwi) from was determined. The nucleotide sequence of PlAMV-Gunwi was most closely related to a Russian isolate of PlAMV (PlAMV-Ru) collected from but highly dissimilar (~23 %) to other isolates of PlAMV from other plant species.
