Clg2p interacts with Clf and ClUrase to regulate appressorium formation, pathogenicity and conidial morphology in Curvularia lunata.

Ras is a small GTPase that regulates numerous processes in the cellular development and morphogenesis of many organisms. In this study, we identified and functionally characterized the Clg2p gene of Curvularia lunata, which is homologous with the Ras protein. The Clg2p deletion mutant (ΔClg2p) had altered appressorium formation and conidial morphology and produced fewer, smaller lesions compared with the wild-type strain.

[Identification of a fungal isolate causing adzuki bean rust in Heilongjiang].

Objective: The aim of the study is to identify the pathogen causing adzuki bean (Phaseolus angularis) rust in Daqing, Heilongjiang province.

Methods: Adzuki bean rust leaves were collected from Daqing, Heilongjiang province, China. A pure culture of rust isolate ZXL01 was obtained by single pustule isolation.
