ABSTRACT This study reports the combination of a transgene-mediated defense mechanism with a conventionally bred resistance in order to improve apple scab resistance. Two cultivars of apple (Galaxy, scab-susceptible, and Ariane, carrying the Vf resistance gene) were transformed with endochitinase and exochitinase genes derived from the biocontrol fungus(More)
Interferon, covalently bound to Sepharose 4B activated by cyanogen bromide, induces the antiviral state in sensitive cells. The antiviral effect is neutralized by antiserum specific to interferon and is recovered thereafter when the antibody is detached from the interferon by treatment at low pH. Binding interferon to Sepharose increases the stability of(More)
Klebsiella pneumoniae utilizes distinct pathways for the anaerobic and aerobic metabolism of glycerol. During anaerobic growth, glycerol is first converted to dihydroxyacetone by glycerol dehydrogenase; subsequent phosphorylation yields dihydroxyacetone phosphate. During aerobic growth, glycerol is initially phosphorylated to yield glycerol 3-phosphate;(More)
, nuclear export signals in vertebrate cyclin B1 keep it out of the nucleus, and Wee1/Myt1-mediated inhibitory phosphoryl-ation of Cdk1 maintains a low level of kinase activity until S phase is complete. These controls presumably evolved to increase the fidelity with which the genome is replicated and segregated to daughter cells. Avoiding premature entry(More)
Based on the exploration of data generated by genome sequencing, a bioinformatics approach has been chosen to identify the biosynthetic pathway of the siderophores produced by Aeromonas species. The amonabactins, considered as a virulence factor, represent a family of four variants of catechol peptidic siderophores containing Dhb, Lys, Gly, and an aromatic(More)
