Alterations in carotenoid synthesis accompanying mutation in Corynebacterium michiganense.
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...
متن کاملMode of Transmission of Corynebacterium insidiosum by Ditylenchus dipsaci.
Transmission of Corynebacterium insidiosum (McCull.) Jensen (cause of bacterial wilt in alfalfa) by the stem and bulb nematode Ditylenchus dipsaci (Kiihn) was demonstrated by Hawn (3) . Disease development in plants where D. dipsaci was the vector was comparable to that in the controls where wilt was induced by the root-ball soak method devised by Cormack, Peake and Downey (1) . Furthermore, th...
متن کاملA Phytotoxic Glycopeptide from Cultures of Corynebacterium insidiosum.
Cultures of Corynebacterium insidiosum produce an extra-cellular phytotoxic glycopeptide that possesses the ability to wilt plant cuttings. Wilt induced by this glycopeptide is directly dependent upon time and upon concentration with measureable wilt occurring in 40 nm solutions in 1 hour. The organism produces 1.3 grams toxin/liter of culture medium. The toxin was purified, and the physical, c...
متن کاملSDS-PAGE and Western blot analysis of somatic and extracellular antigens of Corynebacterium pseudotuberculosis
Different techniques to isolate secreted, cell-surface located and somatic fractions of Corynebacterium pseudotuberculosis have been studied by SDS-PAGE and immunoblotting, by using a pool of sera from naturally infected goats. The secreted antigens were obtained from culture supernatant of the bacteria grown in a chemically defined medium or in Brain Heart Infusion medium. The surface fraction...
متن کاملEffects of Temperature and Inoculation Timing on the Meloidogyne hapla/Corynebacterium insidiosum Complex in Alfalfa.
Hunt et al. (2) and Norton (4) showed that the northern root-knot nematode, Meloidogyne hap/a Chitwood, increased the incidence of bacterial wilt in alfalfa. Hunt et al. (2) also f o u n d t h e b a c t e r i a l wilt organism, Corynebacterium insidiosum (McCuU) H. L. Jens., in plant tissue that had been inoculated only with the bacteria. This would indicate that the role of M. hapla is somethi...
