Insights

Two Myxomycetes species, Fuligo septica and Stemonitis herbatica, were identified as causing slime mold on sweet potato plants in Daejeon, Korea. This marks the first documented occurrence of these slime molds affecting sweet potatoes in the region.

Area of Science:

  • Mycology
  • Plant Pathology
  • Agricultural Science

Background:

  • Slime molds can affect various plant species, impacting crop health and yield.
  • Accurate identification of plant pathogens is crucial for effective disease management.

Purpose of the Study:

  • To identify the Myxomycetes species responsible for slime mold symptoms on sweet potato plants in Daejeon, Korea.
  • To provide the first report of Fuligo septica and Stemonitis herbatica associated with sweet potato in Korea.

Main Methods:

  • Field surveys were conducted in Daejeon, Korea, to collect symptomatic sweet potato specimens.
  • Morphological characteristics of the Myxomycetes were examined for species identification.

Main Results:

  • Two species of Myxomycetes were identified: Fuligo septica and Stemonitis herbatica.
  • These species were found to cause slime mold symptoms on sweet potato plants.

Conclusions:

  • Fuligo septica and Stemonitis herbatica are identified as causal agents of sweet potato slime mold in Korea.
  • This study establishes the first record of these Myxomycetes on sweet potato in the region, contributing to Korean plant pathology knowledge.

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 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...

Fungal Phylum Basidiomycota

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

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...
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 Tenericutes01:24

Bacterial Phylum Tenericutes

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
