Diversity of Protists III01:27

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
Fungal Group Zygomycota01:29

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
Diversity of Protists IV01:27

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

  • Mycology
  • Fungal Taxonomy
  • Molecular Phylogenetics

Background:

  • Alternaria is a diverse fungal genus with saprobic, endophytic, and pathogenic species.
  • Previous DNA studies indicated non-monophyletic genera and clades within the Alternaria complex, challenging traditional morphology-based classifications.
  • The Alternaria complex was previously understood to comprise nine genera and eight sections.

Purpose of the Study:

  • To delineate phylogenetic lineages within Alternaria and allied genera using multi-gene sequence data.
  • To revise the taxonomic framework of the Alternaria complex based on molecular evidence.
  • To provide a more accurate classification of fungal species within this group.

Main Methods:

  • Phylogenetic analysis using nucleotide sequence data from multiple gene regions (18S nrDNA, 28S nrDNA, ITS, GAPDH, RPB2, TEF1-alpha).
  • Comparative analysis of DNA sequence data with existing morphological classifications.
  • Taxonomic revisions including synonymization, new combinations, new names, and new sections.

Main Results:

  • A well-supported Alternaria clade was identified, containing 24 internal clades and six monotypic lineages.
  • Thirteen genera (Allewia, Brachycladium, Chalastospora, Chmelia, Crivellia, Embellisia, Lewia, Nimbya, Sinomyces, Teretispora, Ulocladium, Undifilum, Ybotromyces) were synonymized with Alternaria.
  • A new genus, Paradendryphiella, was described to accommodate Embellisia annulata, Dendryphiella salina, and Dendryphiella arenariae.
  • 32 new combinations, 10 new names, and 16 new Alternaria sections were proposed.
  • Other genera previously associated with Alternaria were placed in different families (Pleosporaceae, Leptosphaeriaceae).

Conclusions:

  • The study provides a robust phylogenetic framework for the Alternaria complex, resolving previous taxonomic ambiguities.
  • The emended generic circumscription of Alternaria and the establishment of new sections offer a refined classification system.
  • This work facilitates a better understanding of the evolutionary history and diversity within the Alternaria group.
