Abstract

Previous environmental surveys of eukaryotic diversity using the small subunit ribosomal RNA (SSU rRNA) gene have revealed many clone sequences that branch near the base of Fungi. In this work, we demonstrate that many of these sequences, including those of the environmental clade LKM11, forma monophyletic and strongly supported group that also includes two sequences derived from the parasitic genus Rozella. This novel clade, called here "Rozellida", is the deepest branch of true fungi so far identified, and appears to be extremely diverse in the environment. (C) 2009 Elsevier GmbH. All rights reserved.

Fungus

A fungus (: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which, by one traditional classification, includes Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls.

Spectral sequence

In homological algebra and algebraic topology, a spectral sequence is a means of computing homology groups by taking successive approximations. Spectral sequences are a generalization of exact sequences, and since their introduction by , they have become important computational tools, particularly in algebraic topology, algebraic geometry and homological algebra. Motivated by problems in algebraic topology, Jean Leray introduced the notion of a sheaf and found himself faced with the problem of computing sheaf cohomology.

Exact sequence

An exact sequence is a sequence of morphisms between objects (for example, groups, rings, modules, and, more generally, objects of an ) such that the of one morphism equals the kernel of the next. In the context of group theory, a sequence of groups and group homomorphisms is said to be exact at if . The sequence is called exact if it is exact at each for all , i.e., if the image of each homomorphism is equal to the kernel of the next. The sequence of groups and homomorphisms may be either finite or infinite.
