Bacterial Phylum Actinobacteria01:30

Bacterial Phylum Actinobacteria

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
Bacterial Phylum Proteobacteria01:26

Bacterial Phylum Proteobacteria

Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...
Deep Sea Microbial Ecology01:18

Deep Sea Microbial Ecology

The deep ocean and its underlying sediments represent vast, largely unexplored microbial habitats that extend far beyond the sunlit photic zone. The photic (euphotic) zone typically spans the upper ~100–200 meters of pelagic waters in the open ocean, but its depth varies geographically and seasonally, where sufficient light supports photosynthetic life. Below this lies the deep sea, spanning roughly 1000–6000 meters (bathypelagic to abyssal zones), with deeper hadal trenches extending beyond...
Bacterial Phylum Firmicutes01:27

Bacterial Phylum Firmicutes

Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...
Bacterial Phylum Bacteroidota01:26

Bacterial Phylum Bacteroidota

The phylum Bacteroidota includes over 700 species classified into four primary orders: Bacteroidales, Cytophagales, Flavobacteriales, and Sphingobacteriales. These gram-negative, non-sporulating rods exhibit saccharolytic capabilities and can be aerobic or fermentative, encompassing obligate aerobes, facultative aerobes, and obligate anaerobes. Many species display gliding motility, though some are nonmotile or use flagella. The genus Bacteroides is well-studied due to its significant role in...
Bacterial Phylum Cyanobacteria01:30

Bacterial Phylum Cyanobacteria

Cyanobacteria are a diverse group of oxygenic, phototrophic bacteria that played a pivotal role in converting Earth’s atmosphere from anoxic to oxygen-rich billions of years ago. They exhibit remarkable morphological diversity, ranging from unicellular forms to filamentous types, with cell sizes varying between 0.5 μm and 100 μm. Cyanobacteria are classified into five groups: Chroococcales (unicellular, dividing by binary fission), Pleurocapsales (unicellular, dividing by multiple fission),...

Area of Science:

  • Mycology
  • Fungal Taxonomy
  • Molecular Phylogenetics

Background:

  • The Capnodiaceae family, commonly known as sooty molds, comprises fungi with complex taxonomic histories.
  • Previous classifications have been challenged by new data and the discovery of new species.

Purpose of the Study:

  • To re-examine type specimens of selected Capnodiaceae genera.
  • To clarify the phylogenetic relationships within the Capnodiaceae using molecular data.
  • To describe new species and epitypify existing ones.

Main Methods:

  • Re-examination and illustration of type specimens of various genera.
  • Molecular phylogenetic analysis using nuclear large and small ribosomal DNA (rDNA) sequences.
  • Isolation and sequencing of new sooty mold collections from Thailand.

Main Results:

  • Several genera were excluded from Capnodiaceae and transferred to other families (Chaetothyriaceae, Micropeltidaceae, Mycosphaerellaceae).
  • The genus Capnophaeum was deemed doubtful due to a lost type specimen.
  • The nuclear rDNA phylogeny provided a clearer understanding of Capnodiaceae relationships.
  • Four new species were described, and Phragmocapnias and Scorias were epitypified.

Conclusions:

  • The study clarifies the taxonomy and phylogenetic placement of several genera within and related to Capnodiaceae.
  • New species descriptions and epitypifications contribute to a more stable and accurate classification of sooty molds.
  • Molecular data is crucial for resolving taxonomic uncertainties in fungal families.
