Poly gamma glutamic acid (γ-PGA)
γ-PGA, a polyamino acid consisting of L- and D-glutamic acids linked by γ-amide bonds, to enhance the utilization rate of fertilizers.
γ-PGA enhances the ability of plants to absorb nutrients;
γ-PGA promoting plant growth.
γ-PGA synergistically improves the utilization of fertilizers and promotes nitrogen metabolism γ-PGA also induces an influx of extracellular Ca2+
in organelles into the cytoplasm, increasing Ca2+
-ATPase levels in plant cells.
γ-PGA has excellent antifreeze activity to protect plant from undesirable deterioration caused by freezing and thawing
