Interactions between Potato Lectin and some Phytobacteria in Relation to Potato Tuber Decay caused by Erwinia carotovora

Induction of Resistance or Susceptibility

“…For example, infiltration of chitin oli gomers, efficient inhibitors of cell agglutination or LPS precipitation by lec tins, did not interfere with the tobacco leaf hypersensitive reaction against avirulent strains of P. solanacearum. Many strains of Erwinia carotovora were agglutinated by potato lectin regardless of their pathogenicity to potatoes, and there was no definite correlation between cell agglutination by lectins and pathogenicity of bacteria belonging to several genera (35). Soybean lectins agglutinated cells of Xanthomonas phaseoli var.…”

The biochemical basis of resistance of potatoes to soft rot Erwinia spp.—a review

“…However, no correlation between agglutination and avirulence was found in attempts to demonstrate that potato lectin was involved in resistance to Erwinia spp. (Ghanekar & Perombelon, 1980). Another group of proteins thought to be involved in resistance of potatoes to some viral, bacterial and fungal pathogens are the pathoge- Tugaye et ai, 1979).…”

Study of antimicrobial activities of chitinases from a potato prototype cultivated in Bangladesh

“…The bacterial agglutination might be due to the presence of cognate glycan antigen on the cell surface of induced bacteria. The inhibition study suggested that the bacterial agglutination occurred as a result of the interaction of lectins with bacterial surface carbohydrates (Ghanekar and Pérombelon, 1980). The result showed that Pseudomonas aeruginosa, Shigella dysenteriae, Salmonella typhi and Klebsiella sp.…”
