Candidate effectors contribute to race differentiation and virulence of the lentil anthracnose pathogen Colletotrichum lentis.

ABSTRACT:

Background

The hemibiotroph Colletotrichum lentis, causative agent of anthracnose on Lens culinaris (lentil) was recently described as a new species. During its interaction with the host plant, C. lentis likely secretes numerous effector proteins, including toxins to alter the plant's innate immunity, thereby gaining access to the host tissues for nutrition and reproduction.

Results

In silico analysis of 2000 ESTs generated from C. lentis-infected lentil leaf tissues identified 15 candidate effectors. In planta infection stage-specific gene expression waves among candidate effectors were revealed for the appressorial penetration phase, biotrophic phase and necrotrophic phase. No sign of positive selection pressure [ω (dN/dS) < 1] in effectors was detected at the intraspecifi
