Plants activate immunity upon recognition of pathogen-associated molecular patterns. Although phytopathogens have evolved a set of effector proteins to counteract plant immunity, some effectors are perceived by hosts and induce immune responses. Here, we show that two secreted ribonuclease effectors, SRN1 and SRN2, encoded in a phytopathogenic fungus, Colletotrichum orbiculare, induce cell death in a signal peptide- and catalytic residue-dependent manner, when transiently expressed in Nicotiana benthamiana.

Proanthocyanidins (PACs) have various bioactivities, such as being anti-bacterial, anti-cancer, and anti-oxidant. Consequently, they have been vigorously studied for the development of new natural bioactive compounds. Recently, PAC was isolated from leaves and pseudostems of the medicinal plant Alpinia zerumbet (Pers.

Article Synopsis
  • Plant pathogens release proteins called effectors that help them infect host cells and manipulate their functions.
  • The study explores a hypothesis that these fungi utilize a set of conserved effectors during their dual lifestyle phases (biotrophic and necrotrophic) to facilitate infection.
  • Researchers identified seven conserved effector candidates through genomic comparisons, and one, CEC3, was shown to cause host cell death and nuclear expansion, indicating its significant role in the infection process across different species.

Members of the Colletotrichum gloeosporioides species complex are causal agents of anthracnose in many commercially important plants. Closely related strains have different levels of pathogenicity on hosts despite their close phylogenetic relationship. To gain insight into the genetics underlying these differences, we generated and annotated whole-genome assemblies of multiple isolates of C.
