[Phytopathological tests with Pseudomonas aeruginosa (author's transl)]. 1977

D Knösel, and E Lange

Several strains of Pseudomonas aeruginosa were investigated for pathogenicity to plant tissue. Inoculations into the intercellular spaces of leaves of Vicia faba (28 degrees C) and Vinca rosea (36 degrees C) showed negative results. In leaves of Nicotiana tabacum (32 degrees C) the bacteria multiplied; the tissue reacted to form partial lesions and necrosis. Neither in culture filtrates of the bacteria nor in eluates of inoculated leaves pectolytic and cellulolytic enzymes or breakdown products of these could be obtained. Whilst the proteolytic activity was high, symptoms for effects on the plant tissue, however, were not observed. Although this bacterium may be able to multiply after injection into tobacco leaf, the general question about pathogenicity to plants must be denied.

UI MeSH Term Description Entries
D010935 Plant Diseases Diseases of plants. Disease, Plant,Diseases, Plant,Plant Disease
D010944 Plants Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE. Plant

D011096 Polygalacturonase A cell wall-degrading enzyme found in microorganisms and higher plants. It catalyzes the random hydrolysis of 1,4-alpha-D-galactosiduronic linkages in pectate and other galacturonans. EC 3.2.1.15. Pectin Depolymerase,Pectinase,Endopolygalacturonase,Depolymerase, Pectin
D011550 Pseudomonas aeruginosa A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.
