Research Directions

Plant-fungal symbioses are common in nature. However, these symbiotic relationships could be dynamic, ranging from mutualistic, commensal, to parasitic. The outcomes of these interactions are often based on the communications and benefits exchanged between the plant host and the associated fungi. The plant-fungal interactions not only determine the mycobiome (i.e. fungal communities) of plants, the long-term co-evolution between them also shape the biodiversity of both plant and fungi. Plant and fungi together play critical roles in global nutrient cycling and ecosystem functioning. Therefore, understanding plant-fungal interaction is fundamental for us to prepare for the ever-changing environment.

Our lab uses integrated approaches to study plant-fungal symbiosis. In particular, we implement next-generation sequencing (i.e. amplicon sequencing, metagenomics, metatranscriptomics) in combination with data of phenotypes and environmental variables. With this information, we aim to understand the following questions in the forest and agricultural systems in Taiwan or nearby regions.

-Community Ecology: How do plant diversity and distribution shape the associated fungal community?

-Functional Ecology: What are the functionalities of different fungal assemblies in association with plants? What are the environmental factors that influence the mycobiome functionalities?

-Fungal systematics: Are there fungal diversity hidden in association with plants, if so, how are they related to other lineages of fungi evolutionarily?

 

Currently, we focus on the following plant-fungal systems:

  • Bryophytes-associated fungi

Bryophytes represent the earliest plant lineage in the terrestrial ecosystem. Therefore, knowledge of bryophyte-fungal interactions can provide key insights in plant-fungal co-evolution.

  • Ectomycorrhizal fungi

In general, ectomycorrhizal fungi help their plant hosts to gain nitrogen and other nutrients from soil. In return, they acquire carbon sources from the plant hosts.

Plant-ectomycorrhiza associations often requires high specificity, making it a good model to examine the establishment and maintenance of plant-fungal symbiosis.

  • Grass-associated epiphytes

Epiphytic fungi are common in grass species (the family Poaceae) but are often neglected in studies. Because many grass species are of high economic values to human, understanding the potential benefits and harm grass epiphytic fungi may have is of critical importance.
