Medicago TERPENE SYNTHASE 10 Is Involved in Defense Against an Oomycete Root Pathogen.

abstract：:The effect of ozone was studied on the peroxidase activity from various compartments of Sedum album leaves (epidermis, intercellular fluid, residual cell material, and total cell material). The greatest increase following a 2-hour ozone exposure (0.4 microliters O(3) per liter) was observed in extracellular peroxidase...
