Anoectochilus roxburghii is an endangered medicinal plant with high economic value in Vietnam, but its population is decreasing due to overexploitation and unfavourable conditions. The base line distribution survey of A. roxburghii in Bach Ma National Park (BMNP) was carried out for the first time in this study. Survey lines were established through interviews to develop field surveys and collect ecological characteristics.

Rice is a critical crop for the delivery of calories and essential micronutrients to the human diet. Biofortification of rice with zinc (Zn) and iron (Fe) aims to combat the health issues associated with “hidden hunger”. Arbuscular mycorrhizal (AM) fungi have been explored for their potential to enhance Zn and Fe uptake in rice products.
