Thailand’s coastal ecosystems, particularly its mangroves, are rich in biodiversity and play critical roles in coastal protection, carbon storage, and marine productivity. However, these ecosystems face severe threats from climate change, pollution, and habitat degradation. Genomic conservation in Thailand seeks to protect the genetic diversity of mangroves by using modern techniques such as DNA sequencing and genetic monitoring.
In this interview, Wirulda Pootakham, the Director of Thailand’s National Omic Centre, talks to NewsMedical about genomic conservation in Thailand’s mangroves.
Could you tell us about your job at the National Omic Centers and how you came to specialize in ecosystems like mangroves?
My name is Wirulda Pootakham. I am the Head of the Genomic Research Lab at Thailand’s National Omic Centre. My colleagues and I conduct genomic research, focusing on genetic diversity in crucial ecosystems such as mangrove forests.
These ecosystems are important for Thailand’s biodiversity and are sensitive to natural and human-induced stressors. Understanding their genetic makeup might help ensure their persistence despite considerable threats from climate change and habitat destruction.

Could you elaborate on the key species found in Thailand, the risks they face, and why genetic diversity is so important to their resilience?
Thailand’s mangroves are home to approximately 81 species, with 34 designated “true” mangroves. The principal species are Sonnertia, Rhizophora, Ceriops, and Bruguiera.
Most of these species grow in southern Thailand, particularly along the shore and intertidal zones. Unfortunately, over the last five decades, almost 60 % of our mangrove forests have been devastated due to deforestation, aquaculture expansion, and urbanization.
Genetic variety is critical for mangroves because it allows plants to adapt to environmental stressors, including rising temperatures, salinity fluctuations, and disease. Previous restoration projects did not focus on genetic diversity, reducing resilience. Our research seeks to solve this by supporting genetically varied populations in restoration efforts, making them more resistant to attacks.
Tackling Ecosystem Challenge with MGI Sequencing Technology in Thailand
How can sequencing technologies contribute to mangrove ecosystem studies?
Sequencing technologies provide detailed genomic information that helps researchers understand the adaptations of mangroves to their challenging intertidal environments.
These technologies enable the assembly of high-quality reference genomes, which are essential for studying genetic traits linked to stress tolerance, reproduction, and survival in saline and hypoxic conditions.
This genetic insight supports conservation efforts by identifying traits critical for resilience and restoration, enabling more informed management of mangrove ecosystems.

Could you explain how MGI’s technology has helped you enhance your research on mangroves?
MGI has been a key collaborator in supplying us with high-quality sequencing technology. We have employed MGI-seq for whole-genome sequencing and other applications, such as RAD-seq, to quantify genetic diversity accurately.
So far, we have sequenced around 15 of Thailand’s 80 mangrove species. This method has also enabled us to find SNP markers, which are crucial for assessing genetic diversity within and between animal populations.
These findings are critical with rising ocean temperatures triggering bleaching events, as we experienced this year. Our work with MGI also includes essential agricultural crops like rice, sugarcane, and corn, where genetic insights might improve resilience to environmental changes.

How can technologies like RAD-seq help address the challenges associated with studying mangroves?
Studying mangroves presents several challenges, including understanding their genetic diversity, biodiversity, and evolutionary adaptations. Restriction Site-Associated DNA Sequencing (RAD-seq) technology is very valuable in addressing these challenges.
It provides sufficient Single Nucleotide Polymorphism (SNP) data to comprehensively analyze the genetic variation of mangrove populations. This allows researchers to study biodiversity, genetic structure, and evolutionary history more effectively.
By identifying key genetic markers, RAD-seq enables us to understand how mangroves have evolved and adapted, which is essential for their conservation and restoration efforts. Moreover, this technique can help identify endangered or vulnerable species within mangrove ecosystems, further supporting their protection
