Purification and Characterization of an Endophytic Fungal Proteinase That Is Abundantly Expressed in the Infected Host Grass.

abstract：:The cell separation aspect of abscission is thought to involve the action of specific cell wall degrading enzymes. Enzymes represent synthesis which in turn is preceded by the synthesis of specific RNA molecules, and it follows that inhibition of either of these processes would also block abscission. Since abscission ...
