Used in plant molecular biology research to quantify histone deacetylase 9 (HDAC9) enzyme levels in plant tissue samples. Helps study epigenetic regulation involved in plant growth, development, and stress responses. Enables researchers to investigate how HDAC9 influences gene expression by removing acetyl groups from histones, particularly under environmental stresses such as drought, salinity, or pathogen attack. Widely applied in agricultural research to explore crop improvement strategies through epigenetic mechanisms. Suitable for high-throughput screening in studies related to plant defense, flowering time, and cellular differentiation.
