Nano Selenium as a novel Auxin rooting of plants grown in vitro

17/10/2022

The research group of Prof. Dr. Duong Tan Nhut, Tay Nguyen Institute of Scientific Research, has published in the prestigious ISI journal (Q1) on the new role of Nano Selenium in the rooting of plants grown in vitro. This is the world's first publication on the effect of Nano Selenium on rooting of plants grown in vitro, and can be considered as a new auxin (or new Phytohormone). The results of this study are extremely important in the study of plant physiology.

Currently, the research group has successfully applied Selenium nanoparticles in the rooting ability of some plants such as gerbera, rose, passion fruit, etc., and is also studying some of their other effects in study of plant physiology on a variety of plants.

Selenium is known as a micronutrient that plays an important role in human health. However, the importance of this element for plant growth is still being studied. Recently, Selenium nanoparticles (SeNPs) have been found to promote rooting in gerbera in vitro by controlling the biosynthesis of endogenous hormones such as auxin, gibberilin, acid abscisic and cytokinin (https://doi.org/10.1007/s11240-022-02250-3). Besides, SeNPs also cause stomatal opening and closing physiology and positively affect the activity of some antioxidant enzymes such as CAT, APX or SOD.

With these interesting findings, a scientific article about the relevant content was published in the prestigious journal Plant Cell, Tissue and Organ Culture (Q1, ISI). This study is a pioneer for the application of SeNPs in plant micropropagation. This is also the result of the excellent research group that the Vietnam Academy of Science and Technology has supported.
