Abstract Receptor-like cytoplasmic kinases (RLCKs) form a large subfamily of proteins in plants. RLCKs are known to regulate plant immunity bacterial and fungal pathogens. In this study, we analyzed the genome-wide complement maize RLCK genes conducted detailed studies on one RLCK. The genome encodes 192 that largely mirror family other Previous implicated Arabidopsis BOTRYTIS INDUCED KINASE1 (...

The Polygonum orientale L. extracts were investigated for antibacterial activity against Clavibater michiganense subsp. sepedonicum (Spieckermann & Kotthoff) Davis et al., the causal agent of a serious disease called bacterial ring rot of potato. The results showed that the leaf extracts of P. orientale had significantly (p<0.05) greater antibacterial activity against C. michiganense subsp. sep...

Colour mutants of the tomato pathogen, Coynebacterium michiganense, provided an opportunity to determine the nature of this micro-organism's pigments, and the effect of mutation and nutrition thereon. The major pigments of C. michiganense are carotenoids. The parent and mutant strains show distinct qualitative differences in pigment synthesis. The naturally occurring yellow parent type produces...

Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves (Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were also functionally distinct from those of groups I-III. They were active at concentrations < 20 micro...

Fourteen endophytic bacterial isolates were isolated from the rhizome of Curcuma longa L. were characterized on the basis of morphology, biochemical characteristics and 16S rRNA gene sequence analysis. The isolates were identified to six strains namely Bacillus cereus (ECL1), Bacillus thuringiensis (ECL2), Bacillus sp. (ECL3), Bacillus pumilis (ECL4), Pseudomonas putida (ECL5), and Clavibacter ...

Strain UFB2 was isolated from a soybean field soil in Mississippi and identified as a member of Pseudomonas chlororaphis. Strain UFB2 has a broad-spectrum antimicrobial activity against common soil-borne pathogens. Plate assays showed that strain UFB2 was especially efficient in inhibiting the growth of Clavibacter michiganensis 1-07, the causal agent of the devastating bacterial canker of toma...
