Major Sperm Protein Genes from Globodera rostochiensis.
Three genes in the major sperm protein (MSP) gene family from the potato cyst nematode Globodera rostochiensis were cloned and sequenced. In contrast to the absence of introns in Caenorhabditis elegans MSP genes, these genes in G. rostochiensis contained a 57 nucleotide intron, with normal exon-intron boundaries, in the same relative location as the intron in Onchocerca volvulus. The MSP genes ...
متن کاملMolecular Characterization of Aldolase from Heterodera glycines and Globodera rostochiensis.
Fructose-bisphosphate aldolase (EC 4.1.2.13) is a key enzyme in glycolysis. We have characterized full-length coding sequences for aldolase genes from the cyst nematodes Heterodera glycines and Globodera rostochiensis, the first for any plant-parasitic nematode. Nucleotide homology is high (83% identity), and the respective sequences encode 40 kDa proteins with 89% amino acid identity. Genomic ...
متن کاملProbability of Globodera rostochiensis Spread on Equipment and Potato Tubers.
The probability of spreading cysts of Globodera rostochiensis on farming equipment and potato tubers was investigated in naturally infested field plots. The number of cysts recovered from soil that adhered to equipment differed significantly between different pieces of equipment. These differences were related to initial nematode density and, in most cases, to the volume of soil that adhered to...
متن کاملCharacter ization of resistance to Globodera rostochiensis pathotype Ro1 in cultivated and wild potato species accessions from the Vavilov Institute of Plant Industry
Potato cyst nematodes (PCN) collected in six localities in the Leningrad region of North West Russia were identified as Globodera rostochiensis pathotype Ro1 and were used for subsequent resistance tests. Seventynine accessions of cultivated and closely related wild potato species from the VIR collection in Russia were screened on resistance to G. rostochiensis pathotype Ro1 and on the presence...
متن کاملEffects of Host Resistance on the Fecundity of Globodera rostochiensis.
The fecundity of Globodera rostochiensis (RA) females that developed on resistant Rosa and susceptible Katahdin potato cultivars were compared. Cysts collected from each cultivar were bulked, separated into four sizes (> 500 mum, 355-500 mum, 250-355 mum, and < 250 mum), and crushed to determine fecundity as measured by viable egg content (VEC). Fewer and generally smaller cysts developed on Ro...
