Abstract

First report of Diaporthe eres causing leaf blight of Buddhist pine (Podocarpus macrophyllus) in China.

Abstract

In April 2019, a severe foliar blight with over 55% disease incidence was observed on tree-sized Buddhist pine (Podocarpus macrophyllus) cultivated on a landscape road in Nanjing, Jiangsu, China. Typical symptoms were lesions with a dark-brown color, which later became brown, on the upper part of the leaves. The causal pathogen was isolated and identified as Diaporthe eres based on morphological characteristics, molecular data (sequence analysis of the internal transcribed spacer region (ITS), β-tubulin (TUB), translation elongation factor 1-α (TEF), partial calmodulin (CAL), and phylogenetic analysis) and pathogenicity test. This is thought to be the first report of D. eres causing leaf blight of Buddhist pine in China.
