Virulence of Auxotrophic Mutants of Erwinia aroideae

Nature, 1954
The virulence of a pathogen depends upon numerous factors, including the availability of essential nutrilites from the host. If the host cannot supply all these nutrilites, either in quantity or in a form suitable for assimilation, the pathogen cannot proliferate and produce the characteristic reactions in the host.

VASCULAR PATTERNS IN STEMS OF ARACEAE: SUBFAMILIES COLOCASIOIDEAE, AROIDEAE AND PISTIOIDEAE

American Journal of Botany, 1983
The stem vasculature of ten genera of Colocasioideae and three genera of Aroideae was analyzed by films of series of cross sections. The technique was unsuited for the numerous tuberous genera of Aroideae (and Pistia ), which have shortened internodes.

Reasons and consequences of the lack of a sporopollenin ektexine in Aroideae (Araceae)

Flora: Morphology, Distribution, Functional Ecology of Plants, 2006
Abstract The ultrastructure of pollen walls in Araceae is characterized by the absence of a stable sporopollenin outer exine layer in subfamily Aroideae, and by the presence of several distinctive pollen characters typical for the other aroid subfamilies. This article discusses if and to which extent such distinctive pollen characters are mirrored in

Plasmid pEA566 from Erwinia aroideae

Plasmid, 1980
A new plasmid designated pEA566 was isolated from Erwinia aroideae. The molecular weight of the plasmid, as determined by neutral and alkaline sucrose gradient centrifugation, electron microscopy, and agarose gel electrophoresis, was 6.6 X 10(6). The plasmid replicated under relaxed control, had three cleavage sites for KpnI restriction endonuclease ...

Maceration by Erwinia aroideae

Netherlands Journal of Plant Pathology, 1968
Calcium which activates enzymes that split chains of pectic substances also increases the activity of macerating enzymes produced in culture byErwinia aroideae. EDTA suppresses both types of activity. Separation on carboxymethylcellulose gave a number of fractions in each of which there was reasonably close correspondence between macerating, chain ...

Endopectate lyase from Erwinia aroideae

1988
Publisher Summary This chapter describes the assay method and purification procedure of endopectate lyase from Erwinia aroideae . Endopectate lyase activity is determined spectrophotomctrically by measuring the increment of unsaturated compounds at 235 nm absorbance.

[F'ColVColBtrpcys plasmid in Erwinia aroideae].

Genetika, 1978
Erwinia aroideae carries a cryptic plasmid with 30 S sedimentation coefficient. Plasmid F'ColVColBtrpcys does not dissociate in E. aroideae and is replicated under stringent control since the number of plasmid copies per chromosome does not exceed one. The behaviour of F'ColVColBtrpcys plasmid in E. aroideae is characterized by (1) instability observed
