Abstract

Hoseinzadeh A., Davari M. and Habibi-Yangjeh A. 2017. Applications of nanomaterials in the fungal plant diseases management. Plant Pathology Science 6(2):68-77.

The use of nanotechnology in plant disease management has been seriously considered by researchers in recent years. Some of these reteaches have shown the antifungal effects of nano zinc oxide on Botrytis cinerea and Penicillium expansum; nano copper oxide on Aspergillus flavus; silver nanocomposite compounds (SiO₂/Ag₂S) on Aspergillus niger; Fe₃O₄/ZnO/AgBr on Fusarium graminearum, F. oxysporum and Botrytis cinerea, and carbon nanomaterials on F. graminearum. Their antifungal mechanisms are including: degradation of lipid and protein, damage to cell membranes, water channels blocking by nanomaterials and loss of spore water and plasmolysis and the inhibition of growth or destruction of fungal hyphae and prevent the sporulation.

Abstract

Erfani M. and Davari M. 2018. Protease inhibitors and their application against plant pathogens. Plant Pathology Science 7(2):60-72. DOI: 10.2982/PPS.7.2.60
 Proteases cleave the peptide bonds in proteins and in this way prevent protein activity by degrading them. Proteases are classified into four categories: serine proteases, cysteine proteases, aspartic proteases and metalloproteases. Plant pathogens utilize these vital molecules in plant infecting process. In the other hand, the activity of proteases is inhibited by protease inhibitors of plants. Serine is one of the protease inhibitors. The plants produce the materials inhibiting pathogenic proteases. These molecules are produced in plant cells during pathogenic microorganisms and viruses attack. Protease inhibitors are divided into several families based on sequence similarity and structure. Because the risk of pathogen resistance to this defense strategy is low, it seems these molecules could be use for biological control against plant pathogens.
