Abstract

In 2020, leaf spots were observed on Datura innoxia plants in Curitiba, Brazil. Alternaria alternata was identified after isolation from symptomatic leaves through morphological characterization, along with sequencing of the partial tef, gapdh, and rpb2 genes and phylogenetic analysis. Pathogenicity was proven using Koch’s Postulates. This is the first report of this species causing disease in Datura spp. worldwide.

首次报告曼陀罗上的交替孢霉

2020 年，巴西库里提巴的曼陀罗（Datura innoxia）植物上出现了叶斑。通过形态学特征描述、部分 tef、gapdh 和 rpb2 基因测序以及系统发育分析，从有症状的叶片中分离出了交替孢霉。致病性通过科赫定理得到了证实。这是全球首次报道该物种在曼陀罗属植物中致病。
