Monographic Studies in the Nectriaceae, Hypocreales: Nectria, Cosmospora, and Neonectria

子囊菌科包括一些在自然生态系统中最显著和普遍存在的微真菌。这些真菌常见于土壤、腐烂的植物材料、昆虫和其他真菌中。虽然大多数物种是samotes，但其他物种对植物和昆虫或生活在活树的叶子和树干中的内生菌具有致病性。本研究将确定三个主要属的分类：Nectria， Cosmospora和Neonectria。这些属具有重要意义，因为它们包括几种广泛存在的植物病原体和潜在的生物防治剂。尽管这些属在自然和农业生态系统中无处不在且种类繁多，但它们都没有得到现代的专题处理。该项目还将增加少数民族对生物科学的参与，并推进霍华德大学的研究生研究。此外，该项目将增加公共机构中作为培养物的真菌种质资源；增加通过数字数据库提供的生物多样性数据；为那些使用这些真菌作为热带森林干扰指标和努力控制这些真菌引起的疾病的人制作基于网络的识别密钥；将可靠鉴定的真菌诊断性DNA序列存入基因库；为植物病理学家研究感兴趣的物种群体生物学提供依据。

The Nectriaceae (Hypocreales, Ascomycota) includes some of the most conspicuous and ubiquitous microfungi in natural ecosystems. These fungi are common in soils, decaying plant material, insects, and other fungi. While most species are saprobes, others are pathogenic on plants and insects or endophytes living in the leaves and trunks of living trees. This study will define the taxonomy of three major genera: Nectria, Cosmospora, and Neonectria. These genera are significant because they include several species that are widespread plant pathogens and potential biological control agents. Even though these genera are ubiquitous and diverse in natural and agricultural ecosystems, none of them have received modern monographic treatment. This project will also increase the participation of minorities in biological sciences and advance graduate research at Howard University. In addition, this project will increase the available germplasm of fungi as cultures deposited in public institutions; increase biodiversity data available through digital databases; produce web-based identification keys for those using these fungi as indicators of tropical forest disturbance and working to control the diseases caused by these fungi; deposit into GenBank diagnostic DNA sequences of reliably identified fungi; and provide the basis for studies on the population biology of species of interest to plant pathologists.
