Sasanelli, N., Vovlas, N., Trisciuzzi, N., Cantalapiedra-Navarrete, C., Palomares-Rius, J. E., and Castillo, P. 2013. Pathogenicity and host–parasite relationships of Heterodera cruciferae in cabbage. Plant Dis. 97:333-338. Stunted cabbage (‘Lupini’) associated with severe soil infestations by a cyst-forming nematode were observed in large patches of open fields in Castellaneta, province of Tar...

The sustainability of modern agriculture relies on strategies that can control the ability of pathogens to overcome chemicals or genetic resistances through natural selection. This evolutionary potential, which depends partly on effective population size (N e ), is greatly influenced by human activities. In this context, wild pathogen populations can provide valuable information for assessing t...

Above- and belowground plant parts are simultaneously attacked by different pests and pathogens. The host mediates these interactions and physiologically reacts, e.g. with local and systemic alterations of endogenous hormone levels coupled with coordinated transcriptional changes. This in turn affects attractiveness and susceptibility of the plant to subsequent attackers. Here, the model plant ...

Fine structure of the posterior cone of monoxenically cultured Heterodera schachtii is examined. The cone is not evident at the end of the fourth molt, but as the female matures the cone elongates, vulval lips enlarge, and cuticular patterns on the lips are modified. Body wall cuticle (BW) of the cone includes layers A and B, but C is modified or replaced by a network of fibers which correspond...

Fungi associated with sugar beet cyst nematode (Heterodera schachtii Schmidt) in W. Azerbaijan were isolated from different stages during 2002-2004 and studied. Some 300 fungal isolates were obtained. In this paper, 16 species belonging to nine genera are identified. Among them, three species viz. Lecanicillium aphanocladii, Myrothecium verrucaria andPlectosporium tabacinum are as new records t...

The plant parasitic nematode Heterodera schachtii induces specific syncytial feeding sites in the roots of Arabidopsis thaliana from where it withdraws all required nutrients. Therefore, syncytia have to be well supplied with assimilates and generate strong sinks in the host plant's transport system. Import mechanisms and consequent accumulation of sucrose in syncytia were described recently. I...
