Introduction to Sebacinales

Abstract

Molecular and ultrastructural studies have revealed a broad diversity of mycorrhizal associations, due to its inconspicuous basidiomes involving members of the heterobasidiomycetes. Sebacinales are extremely versatile in their mycorrhizal association and are universally present as symptomless endophytes. They are found in field specimens of bryophytes, pteridophytes, gymnosperms and all families of herbaceous angiosperms. The members of Sebacinales are established to perform variety of functions involving increased nutrient uptake; transport of essential nutrients responsible for plant productivity; allowing plants to survive under water, temperature and salt stress and conferring (systemic) resistance to toxins, heavy metal ions and pathogenic organisms along with other beneficial effects such as plant growth promotion, early flowering, higher seed yield and alteration in the secondary metabolites. Recent evidences have indicated proven functions and ubiquity of the members of Sebacinales. There is a strong notion that there may be many such unexplored microbes present in the ecosystem. Future research should be focused for their isolation characterisation and their biotechnological applications.
