Little is known regarding the population biology or reproductive biology of this pathogen in the affected areas. The aims of this study were to investigate the genetic diversity, population structure, and reproductive mode of .

Diversity of Calonectria species from leaves and soils in diseased southern China Eucalyptus plantation.

Calonectria leaf blight (CLB) is one of the best-known diseases of Eucalyptus spp., particularly in Asia and South America. Recently, typical symptoms of leaf and shoot blight caused by Calonectria spp.

species from plantation soils in southwestern China.

Species of are saprobic or plant pathogenic, and widely distributed in soil in tropical and sub-tropical regions of the world. Limited information is available about the species diversity and distribution of in China. The aim of this study was to identify the isolates from soils collected in a plantation in the Yunnan Province of southwestern China.

Wide Distribution of and Associated with Diseased Leaves in Plantations in Southern China.

Species of and represent over 40% of the fungi identified on eucalypt leaves worldwide. These include some important pathogens that mainly cause leaf blight and spot, and result in increasingly negative impacts on global commercial eucalypt industries. plantations are commonly cultivated in southern China for solid wood and pulp products.

High-quality genome resource of Lasiodiplodia pseudotheobromae associated with die-back on Eucalyptus trees.

Objectives: Lasiodiplodia pseudotheobromae is an important fungal pathogen associated with die-back, canker and shoot blight in many plant hosts with a wide geographic distribution. The aim of our study was to provide high-quality genome assemblies and sequence annotation resources of L. pseudotheobromae, to facilitate future studies on the systematics, population genetics and genomics of the fungal pathogen L.

Evidence of High Genetic Diversity and Differences in the Population Diversity of the Eucalyptus Leaf Blight Pathogen from Diseased Leaves and Soil in a Plantation in Guangxi, China.

is an important causal agent of leaf blight in southern China. This pathogen causes tree disease across numerous regions in southern China. In addition to diseased leaves, has occasionally been isolated from soil in plantations.

Wide Distribution and Intraspecies Diversity in the Pathogenicity of in Soil from Plantations in Southern Guangxi of China.

spp. are extensively cultivated in southern China because of their adaptability and versatile timber production. leaf blight caused by species is considered a major threat to trees planted in China.

Identification and pathogenicity of species (Cryphonectriaceae, Diaporthales) on species in Southern China.

The family of Cryphonectriaceae (Diaporthales) contains many important tree pathogens and the hosts are wide-ranging. Tree species of were widely planted as ornamental trees alongside city roads and villages in southern China. Recently, stem canker and cracked bark were observed on 2-6 year old and in several nurseries in Zhanjiang City, Guangdong Province, China.

Characterization of Species from Diseased Plantation-Grown , spp., and in Southern China.

Fungi from () have been reported as pathogens, endophytes, or saprophytes from various woody plants in different countries. Recently, isolates were obtained from the dead twigs of , spp., , and in Guangdong, Guangxi, Hainan, and Fujian Provinces in southern China.

Diversity and Distribution of Species in Soils from × . , , and Plantations in Four Provinces in Southern China.

The species of include many notorious plant pathogens and are widely distributed around the world. Leaf blight caused by species is considered one of the most prominent diseases in plantations in China. Some species isolated from soils in plantations are highly pathogenic to inoculated genotypes.

Soil-borne (Hypocreales, Nectriaceae) associated with plantations in Colombia.
