Research ArticleOpen accessIn the abstractEffects of ced-9 dsRNA on Caenorhabditis elegans and Meloidogyne incognitaRobert T. Gaeta, Abdellatif Bahaji, Glenda W. Polack, Alejandro Calderón-UrreaAbstract: Problem Statement: In metazoans Programmed Cell Death (PCD) is essential for proper development. Suppression of PCD is needed to guarantee cell survival and in the nematode Caenorhabditis elegans the regulation of PCD is accomplished by the function of the ced-9 gene. Approach: In this work the use of double stranded RNA (dsRNA) to knock-down ced-9 gene function was tested … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 9,456 accessesView PDFCite
