NGHIÊN CỨU THỰC VẬT HỌC VÀ DI TRUYỀN HỌC CỦA LOÀI MẮM ĐEN (AVICENNIA SP.) TẠI VIỆT NAM

Abstract

Background: Mam trees (Indian mangrove) distributed in many coastal areas from the North to the South of Vietnam. Currently, there is no study on plant characteristics and genetic sequence to accurately identify the species name. Objectives: Determining plant characteristics and studying gene sequence to accurately identify the scientific name of Indian mangrove that were collected in 3 districts in Ca Mau province, Vietnam. Materials and methods: The roots, stems, and leaves of Indian mangrove were collected in 3 different districts in Ca Mau province which were cut, dyed, observed under optical microscope and characterized. Research on gene sequencing based on the Bold System and comparison by Blast method on NCBI gene bank system to identify species. Results: Botanical features and genetic characterizations of Indian mangrove grown in Vietnam was conducted on three samples collected in Ca Mau province, by RBCL gene sequencing, as it is commonly used. In the study of species differentiation, samples of Indian mangrove are suitable to be classified into three groups due to their differences in morphology and genotype. Conclusions: This gene sequence study has determined that the scientific name of Indian mangrove which were collected in 3 different districts of Ca Mau province is Avicennia officinalis and belongs to the Acanthaceae family.
