The aim of this study was to use scanning electron microscopy (SEM) to elucidate the infection process of Pyricularia oryzae on leaf surfaces of wheat seedlings. Wheat seedlings were inoculated with a conidial suspension of P. oryzae (105 conidia/mL), and leaf samples were collected for observation via SEM. The first blast symptoms appeared 48 h after(More)
It is well known that silicon (Si) increases the resistance of many plant species to several pathogens, including Pyricularia oryzae, the causal agent of blast on wheat, but the mechanisms underlying such resistance remain elusive. This study was carried out to investigate whether Si-mediated wheat resistance to blast could be linked to host defense(More)
Calcium (Ca) is an essential macronutrient for plant growth, but its role in plant disease resistance remains largely elusive. Here, we investigated whether Ca increases the abundance of defense-related transcripts and enhances wheat resistance to leaf blast, caused by Pyricularia oryzae. To address these issues, wheat plants were grown in nutrient solution(More)
Macrospora leaf spot, caused by Stenocarpella macrospora, is an important disease of maize. However, little information is available regarding the infection process of this fungus on maize leaves. This study aimed to describe stages of the infection process of S. macrospora on maize leaves by using both light and scanning electron microscopy. The adaxial(More)
