First Report of Leaf Spot Disease in Angelica dahurica Caused by Phoma bellidis in China

Abstract

Angelica dahurica is a perennial herb belonging to the Umbelliferae family that has been used as a valuable traditional Chinese medicine. In August 2013, leaf spot disease in A. dahurica was first observed at the Medicinal Herb Garden in Shenyang Agricultural University, Shenyang, Liaoning, China. Morphological assessment, evaluation of culture characteristics, internal transcribed spacer and beta‐tubulin sequence analysis and pathogenicity identified the causal agent as Phoma bellidis. To our knowledge, this is the first report of leaf spot disease in A. dahurica that was caused by P. bellidis.

Didymellaceae species associated with tea plant (Camellia sinensis) in China

“…They were isolated from diseased tea plant leaves and had strong virulence (Figs 11 , 12 ), suggesting that D. segeticola may be the causal agent of foliar diseases in tea plants. Didymella species have been reported to cause leaf spot on many plants, such as Angelica dahurica ( Xu et al 2016 ), Bellis perennis ( Chen et al 2015a ), Chrysanthemum morifolium ( Liu et al 2019 ), C. sinensis ( Ren et al 2019 ; Wang et al 2021 ), Eleocharis dulcis ( Lv et al 2011 ), Lodium multiflorum ( Liu et al 2022 ) and Zanthoxylum bungeanum ( Yang et al 2022 ). Especially, Ren et al (2019) have also proved that D. segeticola is a causal agent of leaf spot on tea plants in China.…”

The inhibition of photosynthesis of Angelica dahurica caused by early bolting

“…"Bai Zi" is the dried root of A. dahurica, which is known as a kind of traditional Chinese herbal medicine, rich in volatile oils and coumarins. It is widely used in pharmaceuticals, spices, cosmetics and for the treatment of toothache, cold, headache [3,4]. Growth of A. dahurica is usually divided into three stages: vegetative stage (V-stage), bolting stage (B-stage) and summer dormancy stage (D-stage) [5].…”
