Context
- Scientists have discovered a new species of fungus in Kerala named as ‘Paramyrothecium indicum’.
Details
- Named after India, ‘Paramyrothecium indicum’ (Ascomycota, Stachybotryaceae), is a new species of phytopathogenic fungus.
- It exists as a parasite on plants and is associated with emerging leaf spots on the wild hibiscus plans near Peechi-Vazhani Wildlife Sanctuary in Thrissur district of Kerala.
- Phytopathogen fungi are responsible for “serious plant diseases which might negatively affect crop productivity”.
- Most of the Paramyrothecium are phytopathogens, a parasite surviving on a plant host.
Importance of Paramyrothecium indicum
- The scientists have pointed out that the Western Ghats region of Kerala is renowned for its abundant fungal diversity, including numerous species endemic to the specific area.
- The climatic conditions, rainfall, and phanerogamic vegetation are congenial for the growth and development of different kinds of pathogenic and non-pathogenic fungi
- This finding underscores the importance of ongoing exploration and research into the diverse flora, fauna, and fungi in the Western Ghats.
- Paramyrothecium leaf spots are a type of fungal disease that can affect a variety of plants. To control and manage these leaf spot diseases, they said, surveillance and early detection of causal agents is essential.
- The disease can be prevented by pruning and removing infected leaves to reduce the source of infection.
- Because this infects all plant leaves within a short time once climatic conditions are favourable.
- Some biological preventive solutions are available in the market that can be used for the control of this disease.
- In severe cases, fungicides can be very effective for the control of Paramyrothecium leaf spots.
- The scientists have also observed that “some species of Paramyrothecium produce secondary metabolites with bio-herbicidal potentials” and, therefore, may find application in controlling weeds. However, this characteristic requires further exploration.
FUNGI
Fungi, a distinct biological kingdom, are crucial for ecosystems and human activities. Understanding their roles is vital for biodiversity comprehension.
Classification:
- Belong to a separate kingdom: Ascomycota, Basidiomycota, Zygomycota.
- Include yeasts, mushrooms, and molds.
Ecological Roles:
- Decomposers: Recycle nutrients by breaking down organic matter.
- Mycorrhizae: Form symbiotic relationships aiding plant nutrient absorption.
- Pathogens: Cause diseases in plants, animals, and humans.
Economic Importance:
- Food Production: Essential in fermentation for bread, beer, and wine.
- Medicine: Source of antibiotics like penicillin.
- Bioremediation: Assist in environmental pollutant cleanup.
Disease and Health:
- Plant Diseases: Impact agriculture by causing various plant diseases.
- Human Diseases: Fungal infections affect individuals with compromised immune systems.
Biodiversity Hotspots:
- Abundant in biodiversity hotspots like the Western Ghats.
- Recent discoveries, like "Paramyrothecium indicum" in Kerala, highlight ongoing exploration.
