Bean Leaves

The results describe a novel activity of fungal cutinase, the protection of bean leaves from disease. Development of web blight symptoms on bean leaves infected with Rhizoctonia solani (AG-1) was prevented in the presence of cutinase purified from Venturia inaequalis. Instead of disease, small areas of tissue necrosis became visible, and the tissue in which the pathogen was restricted displayed strong autofluorescence beneath the inoculation sites. Mechanical wounding of the leaf surface had no effect on disease development and the permeability of the cuticle was not increased by cutinase action, indicating that surface wounding was not the cause for this novel activity of cutinase. A comparative study involving cutinase and other serine hydrolases revealed that the disease prevention resided in the lipolytic esterase activity rather than the cutinase activity. The pattern of expression of four pathogenesis-related (PR) protein genes provided no evidence for the modulation of known resistance responses of bean leaves in response to cutinase action. The protective mechanism of the esterase activity remains unknown.

Continuous Temperature

Abstract Air and growing medium temperatures affected severity of foot rot of Epipremnum aureum (pothos) caused by Rhizoctonia solani AG4. Maximum daily temperatures of 30°C (86°F) for either air or soil resulted in optimal disease development. Maximum daily temperatures of 35°C (95°F) decreased disease development significantly due to fungal pathogen growth reduction. A continuous temperature of 30°C (86°F) was also too high for significant disease development.

Bacterial Volatiles

ABSTRACT Volatiles of Stenotrophomonas, Serratia, and Bacillus species inhibited mycelial growth of many fungi and Arabidopsis thaliana (40 to 98%), and volatiles of Pseudomonas species and Burkholderia cepacia retarded the growth to lesser extents. Aspergillus niger and Fusarium species were resistant, and B. cepacia and Staphylococcus epidermidis promoted the growth of Rhizoctonia solani and A. thaliana. Bacterial volatiles provide a new source of compounds with antibiotic and growth-promoting features.
