Effects of manganese and zinc on the growth process of Phytophthora nicotianae and the possible inhibitory mechanisms.

ABSTRACT:

Background

Phytophthora nicotianae is a fungal soil-borne pathogen that damages various plant species. Mancozeb and Zineb, fungicides containing manganese (Mn) and zinc (Zn) as the main components, are widely used to control the diseases caused by Phytophthora. However, the inhibition mechanism is still unclear. The purpose of this study was to examine the effects of Mn and Zn on P. nicotianae and to determine possible inhibitory mechanisms of Mn and Zn on sporangiogenesis of P. nicotianae.

Methods

The mycelial growth, sporangium generation, zoosporogenesis and zoospore germination of P. nicotianae were observed under Mn and Zn treatments. The gene (csn4 and csn7) expression levels of P. nicotianae in different growth s
