"Pangenome analysis of Vietnamese rice landraces: Towards the identification of unique genomic regions for rice improvement"
Rice (Oryza sativa L.) is an important food crop, exhibits remarkable genetic diversity across its indica and japonica subgroups, reflecting extensive adaptive evolution and selective breeding. While high-quality single-reference genomes have...

Salt intrusion has caused adverse effects on nutrient uptake, growth and yield of rice plants in the Mekong Delta, Vietnam. The study was aimed to isolate, screen, identify phosphorus (P)-solubilizing purple non-sulfur bacteria (PNSB) from salinity...

Drought is one of the fundamental issues in the current climatic environment and one of the most severe abiotic stresses in many areas of the world. Roots are critical for water and nutrient intake, yet they are rarely the main target of breeding...

With increasing awareness on the global Sustainable Development Goals (SDGs), particularly SDG 3, and evolving public needs, the vision for food and nutrition security has transformed. Within the food system, dietary choices are shaped by food... Read more.MS in Agricultural Economics (University of the Philippines Los Baños)"Analysis of forest dynamics of the evergreen broadleaf forest in the Northern mountainous region of Vietnam"
The study analyzed the forest dynamics of the evergreen broadleaf forests in the Northern mountainous region of Vietnam. Specifically, the study (1) analyzed the change in the overstory tree structure (tree composition, density, biodiversity indices...

(Fagaceae) in Gunung Gede Pangrango National Park Cibodas Biosphere Reserve, Indonesia"
Understanding and addressing the challenges faced by endangered species, like Castanopsis tungurrut, is imperative for biodiversity conservation and ecosystem health. Despite the urgency, existing studies on Castanopsis tungurrut are insufficient... Read more.PhD in Botany (University of the Philippines Los Baños)
