Aggressiveness Variation in Czech Isolates of Erysiphe cichoracearum Pathotype AB1B2CCm
Introduction. Erysiphe cichoracearum /Ec/ is the predominating powdery mildew species on cucurbits in the Czech Republic (5). Its occurrence and spreading on cucurbits can be influenced not only by virulence, but also by aggressiveness of isolates within natural pathogen populations. Both forms of pathogenicity have an impact on plant cultivation and protection and should be considered in resis...
متن کاملTranscriptional profiling of Medicago truncatula during Erysiphe pisi infection
Resistance to powdery mildew has been studied in a number of plant species, yet the molecular mechanisms remain largely unknown. Transcription factors (TFs) play a critical role in the plant defense response by regulating the transcriptional machinery which coordinates the expression of a large group of genes involved in plant defense. Using high-throughput quantitative real-time PCR (qPCR) tec...
متن کاملMolecular and cytological responses of Medicago truncatula to Erysiphe pisi.
SUMMARY Powdery mildew is an economically important disease in a number of crop legumes; however, little is known about resistance to the disease in these species. To gain a better understanding of the genetics of resistance and plant responses to powdery mildew in legumes, we developed a pathosystem with Medicago truncatula and Erysiphe pisi. Screening accessions of M. truncatula identified ge...
متن کاملAdhesion measurements on the attachment devices of the jumping spider Evarcha arcuata.
The feet of the jumping spider Evarcha arcuata attach to rough substrates using tarsal claws. On smooth surfaces, however, attachment is achieved by means of a claw tuft, the scopula. All eight feet bear a tarsal scopula, which is equipped with setae, these again being covered by numerous setules. In E. arcuata, an estimated 624,000 setules, with a mean contact area of 1.7 x 10(5) nm(2), are pr...
متن کاملGenus-specific commensalism of the galeommatoid bivalve Koreamya arcuata (A. Adams, 1856) associated with lingulid brachiopods
We compared shell morphology and DNA sequences of the ectosymbiotic bivalves Koreamya (Montacutidae) attached to two different species of inarticulate brachiopods Lingula collected from South Korea. There are some differences in shell morphology between K. arcuata (A. Adams, 1856) attached to Lingula anatina and K. sp. attached to L. adamsi, such as shell outline, periostracum and hinge teeth. ...
