项目摘要
9708035 Vilgalys Mushrooms are among the most conspicuous groups of fungi found in nature, and are of ecological and economic importance. This project by Dr. Rytas Vilgalys of Duke University and his colleagues in Canada and the U.S. supports the development of a DNA sequence data base for taxonomic studies of mushroom fungi and their allies (usually placed in the order Agaricales, of the basidiomycetes). Although there has been much speculation about the relationships of diverse mushroom groups (gilled or poroid forms, underground "truffle" forms, etc.), little is known about their phylogenetic origins or the characters that reliably define each of the lineages. The taxonomy of mushrooms has traditionally relied on morphological features that are known or suspected to be subject to parallel or convergent evolution, or are phenotypically plastic within species or genera; as a result, many families are considered artificial assemblages, keyed to easily recognizable characters that nonetheless do not correlate with other features of their biology. An independent data set of DNA sequences from the nuclear ribosomal genes, from more than 500 representative species sampled from tropical, temperate, and boreal regions, provides for measurement of mutational differences that can then be used to construct phylogenetic trees for mushroom groups. When compared and integrated with traditional morphological and life-history characters of the fungi, the molecular sequence data will aid researchers in the identification of new or poorly known species, and provide a comparative basis for studies on mushroom ecology and biology. The evolutionary origins and diversity of "fruit body" formation in mushrooms, of their enzymatic capabilities for digesting wood and carbohydrates, and of their general nutritional modes (saprophytic, parasitic, mutualistic) can be studied in a rigorous comparative manner in the context of a well-supported phylogenetic framework that establishes the genealogical connections among species. Dr. Vilgalys is one of the leaders in this new comparative biology of fungi.
小行星9708035 蘑菇是自然界中最引人注目的真菌类群之一,具有生态和经济重要性。这个项目由杜克大学的Rytas Vilgalys博士和他在加拿大和美国的同事们共同完成,他们支持建立一个DNA序列数据库,用于蘑菇真菌及其亲缘菌(通常归入伞菌目,属于担子菌纲)的分类学研究。虽然有很多关于不同蘑菇群(鳃状或多孔状形式,地下“块菌”形式等)的关系的猜测,关于它们的系统发育起源或可靠地定义每个谱系的特征,我们知之甚少。蘑菇的分类传统上依赖于已知或怀疑受到平行或趋同进化的形态特征,或者在种或属内具有表型可塑性;因此,许多科被认为是人工组合,其关键是易于识别的特征,但与其生物学的其他特征无关。一个独立的数据集的DNA序列的核核糖体基因,从500多个代表性的物种从热带,温带和北方地区采样,提供了测量突变的差异,然后可以用来构建蘑菇群的系统发育树。与传统的形态学和生活史特征进行比较和整合,分子序列数据将有助于研究人员鉴定新的或鲜为人知的物种,并为蘑菇生态学和生物学研究提供比较基础。 蘑菇的“子实体”形成的进化起源和多样性,它们消化木材和碳水化合物的酶促能力,以及它们的一般营养模式(腐殖、寄生、互惠),可以在一个得到充分支持的系统发育框架的背景下以严格的比较方式进行研究,该框架建立了物种之间的谱系联系。Vilgalys博士是这一新的真菌比较生物学的领导者之一。
