Isolation and partial characterization of host cell wall surface glycoproteins: their involvement in agglutination, attachment and appressorium formation by piptocephalis virginiana
… possible role in agglutination, attachment and appressorium formation by the mycoparasite. Results obtained by agglutination and attachment tests showed: (1) the two glycoprotein-s are not only an agglutinin responsible for the mycoparasite spore agglutination, but may also serve as a receptor …

ANTIFUNGAL ACTIVITY OF NATURAL AND NATURAL-INSPIRED BIOACTIVE COMPOUNDS TO CONTROL THE RICE BLAST FUNGUS
… cell death, was investigated for its role in appressorium maturation. A series of benzamides containing chelating catechol moieties effectively suppressed appressorium formation, with activity partially reversible by adding exogenous Fe 3 +, highlighting the critical link between iron …

THE ROLE OF PKS1 MEDIATED SECONDARY METABOLISM IN HOST PENETRATION AND COLONIZATION DURING RICE BLAST DISEASE
… A SPECIALIZED INFECTION STRUCTURE, THE APPRESSORIUM, TO PENETRATE THE RICE LEAVES DURING INITIATION OF THE DISEASE. A LAYER OF CONDENSED MELANIN IS FORMED IN THE APPRESSORIUM TO MAINTAIN A HIGH TURGOR PRESSURE THEREIN TO FACILITATE THE HOST PENETRATION. HOWEVER, OTHER MECHANISMS THAT ARE …

The Role of G-Protein Signaling in Pathogenesis in Cercospora zeae-maydis
… All three Gpα genes were required for appressorium formation and pathogenesis. Additionally, all three Gpα genes regulated cercosporin biosynthesis and sporulation. Together, these data demonstrated that the Gpα subunits in Cercospora zeae-maydis regulate pathogenesis and suggest that …

Protein Kinase A Regulates Hyphal Growth by Relieving the Interaction of MoSfl1 with the Cyc8-Tup1 Co-repressor in Magnaporthe oryzae
… oryzae, it regulates surface recognition, appressorium turgor generation, and invasive growth. Two genes in M. oryzae named CPKA and CPK2 encode the catalytic subunits of cAMP-dependent protein kinase A. Previous studies have shown that deletion of CPKA failed to block response to exogenous …

The infection process of Colletotrichum truncatum on lentil
… until 72 hpi, including conidium germination, appressorium formation, and leaf penetration. Results indicated that differences in virulence of the two races may be related to the ability of conidia to germinate and form appressoria, as well as the ability of primary infection hyphae to grow in …

Phylogeny, histological observation, and in vitro fungicide screening and field trials of multiple Colletotrichum species, the causal agents of grape ripe rot
… appressoria was documented on leaves. I observed appressorium formation with isolates of two C. fructicola-like genotypes and C. nymphaeae, as well as secondary conidiation with isolates of C. aenigma, C. fructicola-like genotype 3, and C. nymphaeae on blooms. And finally, benzovindiflupyr, …

Melanin-independent accumulation of turgor pressure in appressoria of Phakopsora pachyrhizi
Appressoria of some plant pathogenic fungi accumulate turgor pressure that produces a mechanical force enabling the direct penetration of hyphae through the epidermis. Melanin functions as an impermeable barrier to osmolytes, which allows appressoria to accumulate high turgor pressure. Deficiency …

Molecular and cellular analyses of pathogenicity and host specificity in rice blast disease
Rice (Oryza sativa L.) production worldwide is constrained by rice blast disease caused by the ascomycetous fungus Magnaporthe oryzae. Rice blast has become a model system for the study of fungal plant diseases based on its global relevance to agriculture and on our ability to apply molecular …
