Comparison of whole-genome amplifications for microsatellite genotyping of Rotylenchulus reniformis Electron. J. Biotechnol.
Arias,Renée S; Stetina,Salliana R; Scheffler,Brian E.
Currently, a large number of microsatellites are available for Rotylenchulus reniformis (reniform nematode); however, two barriers exist for genotyping samples from different geographical areas. The limited amount of nucleic acids obtained from single nematodes which would require their multiplication to obtain enough DNA for testing; and the strictly regulated transport of live samples and multiplication in greenhouse for being a plant pathogen. Whole-genome amplification (WGA) of samples consisting of one and five dead gravid females with their associated egg masses was successfully performed on disrupted tissue using three commercial kits. DNA yield after WGA ranged from 0.5 to 8 µg and was used to test 96 microsatellite markers we previously developed...

Response of cucurbit species to Rotylenchulus reniformis Trop. Plant Pathol.
Torres,Gustavo R. C.; Pedrosa,Elvira M. R.; Siqueira,Kércya M. S.; Moura,Romero M..
The state of Rio Grande do Norte is the major melon (Cucumis melo) producer in Brazil and the reniform nematode Rotylenchulus reniformis has become increasingly important due to damages to that crop and the lack of resistant cultivars and effective control measures. Under these circumstances, eight cucurbit genotypes were screened for resistance or tolerance to a population of R. reniformis in naturally infested field soil, under greenhouse conditions. A high reduction in shoot mass was found in all infected genotypes. Watermelon (Citrullus lanatus) cv. Sugar Baby showed the lowest rate of nematode reproduction.
