Biological Control of the Crown Gall Disease
A combination of the crown gall biocontrol strain K-84 and another antagonist JH-l was better than K-84 alone in controlling some Agrobacterium strains. Strain K-84 surprisingly controlled some resistant Agrobacterium strains when heavy concentrations of K-84 were used. Strain K-84 could control sensitive strains of Agrobacterium up to 48 hr. after wounds were inoculated with the pathogen at te...
متن کاملBiological Control of the Crown Gall Diseases
Six different strains of crown gall bacteria were tested to determine whether the commonly used biocontrol strain, K-84, would present them from infecting the paradox hybrid. Previous research showed that K-84 was highly effective in preventing crown gall infections of English root stock. There was considerable variability among the six strains in ability to cause disease. One of the strains di...
متن کاملIsolation of Agrobacterium Tumefaciens Strains from Crown Gall Disease on Imported Roses Plants in Qazvin Province
Cultivar of roses (Rosa spp.) has been grown in greenhouses in Qazvin region of Iran for local markets. Agrobacterium tumefaciens strains were isolated and identified from six different samples of roses plants imported from the Netherland to Iran. During August and September of 2012, nearly 2-5% of rose plants in two different greenhouses in the province of Qazvin were observed with crown gall ...
متن کاملHormonal control of tobacco crown gall tumor morphology.
The endogenous levels of auxin and cytokinin in teratoma and unorganized tobacco (Nicotiana tabacum L. var Wisconsin #38) crown gall tumor tissues were determined. Teratoma tissues contain levels of auxin and cytokinin favorable for shoot formation, whereas unorganized tumors contain levels of auxin that suppress shoot formation. This conclusion is based upon the observation that when levels of...
متن کاملRecovery of crown-gall tumor cells.
nant animal cells are distinguished from healthy or inflaznmstory cells. In emphasizing the perma nency of the cellular alteration, Kidd (6) states that “Cancercells remain such until they die . . they never turn back en masse towards the benign or normal state. . . .“The inability to accomplish a reversal of malignant to normal cells under con trolled conditions has, however, served as a s...
