摘要

柚木是厄瓜多尔非常重要的热带木材。2017年，在厄瓜多尔的两个省采集了表现出茎溃疡症状的柚木样本。从11株有症状的树木中，获得了11株与Lasiodiplodia相似的分离株。所有分离株在人工接种后在柚木植物上获得诱导的茎溃疡，证实它们是观察到的溃疡症状的原因。用来自两个代表性分离株的完整ITS和部分TEF-α和β-TUB基因序列的串联序列进行贝叶斯推断，将柚木分离株与Genbank中可获得的木犀科Lasiodiplodia的其他序列聚类。这是L。在厄瓜多尔柚木植物上引起茎溃疡的毒瘤。

Characterization of Lasiodiplodia theobromae (Pat.) Griffon & Maubl causing stem canker on Teak (Tectona grandis L.) in Ecuador

Teak is a very important tropical timber in Ecuador. In 2017, teak samples displaying stem canker symptoms were collected in two provinces of Ecuador. From 11 symptomatic trees, 11 isolates resembling a species of Lasiodiplodia were obtained. All isolates obtained induced stem canker on teak plants after artificial inoculation, confirming them as the cause of the observed canker symptoms. Bayesian inference with concatenated sequences of complete ITS and partial TEF-α and β-TUB gene sequences from two representative isolates clustered teak isolates with other sequences of Lasiodiplodia theobromae available in Genbank. This is the first report of L. theobromae causing stem canker on teak plants in Ecuador.

期刊介绍： This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English. Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
