Removing plant pathogens with the sun as a free, available, clean, and sustainable source of energy is interesting. However, there no data for disinfecting major pathogenic bacteria such Pseudomonas syringae Clavibacter michiganensis subsp. by solar ultraviolet radiation. To obtain required time killing these at different temperatures, bacterial suspension active growing cells (approximately 10...

The gram-positive pathogenic bacterium Clavibacter michiganensis subsp. (Cmm) causes bacterial canker disease in tomato, affecting crop yield and fruit quality. To understand how tomato plants respond, the dynamic expression profile of host genes was analyzed upon Cmm infection. Symptoms became evident from third day. As progressed, population increased planta, reaching highest level at six day...

Four homogeneous proteins (Cw18, Cw20, Cw21, Cw22) were isolated from etiolated barley leaves by extraction of the insoluble pellet from a Tris-HCl (pH 7.5) homogenate with 1.5 M LiCl and fractionation by reverse-phase high-performance liquid chromatography. All 4 proteins inhibited growth of the pathogen Clavibacter michiganensis subsp. sepedonicus (EC50s = 1-3 x 10(-7) M) and had closely rela...

Salicylic acid (SA) is known to be involved in the immunity against Clavibacter michiganensis ssp. (Cmm) that causes bacterial canker tomato. To identify candidate genes associated with SA-inducible Cmm resistance, transcriptome analysis was conducted via RNA sequencing tomato plants treated SA. SA treatment upregulated various defense-associated genes, such as PR and GST cotyledons. A comparis...
