Summary
This research discovered and described a new species of fungus found on dead leaves of Dracaena plants in Thailand. The fungus, named Pestalotiopsis dracaenicola, was characterized using both physical features and DNA analysis to confirm it as a previously unknown species. This discovery helps expand our understanding of fungal diversity and plant-fungal relationships.
Impacts on everyday life:
• Contributes to understanding plant diseases that could affect ornamental Dracaena plants commonly used in homes and offices
• Helps inform plant quarantine measures for international trade of ornamental plants
• Advances knowledge of biodiversity that could lead to discovery of beneficial compounds
• Assists in conservation efforts by documenting species before potential habitat loss
• Improves understanding of plant-fungal relationships that could impact agriculture and horticulture
Background
Dracaena is a monocotyledon belonging to the family Agavaceae used as ornamentals, herbs and medicinal plants. While detailed studies exist on fungi associated with other hosts like grasses, bamboo and palms in Thailand, information remains limited on Dracaena-based fungi. Only two Pestalotiopsis species have previously been reported on Dracaena fragrans.
Objective
To investigate microfungi associated with Dracaena leaf litter in Thailand and introduce a novel species in Pestalotiopsis based on morphology and multigene phylogeny.
Results
Two isolates were found to constitute a distinct lineage within Pestalotiopsis, sharing close phylogenetic affinity with P. adusta, P. krabiensis, P. pandanicola and P. papuana. The new species, named Pestalotiopsis dracaenicola, differs from related species in conidial morphology, particularly in size (22-26 × 4-6 μm) and number of apical appendages (1-3).
Conclusion
A new fungal species, Pestalotiopsis dracaenicola, was discovered and characterized from Dracaena leaf litter in Thailand. This finding contributes to the understanding of fungal diversity associated with Dracaena plants and expands the known species within the genus Pestalotiopsis.
