ALTERNATION OF HOST PLANTS AS A SURVIVAL MECHANISM OF LEAFHOPPERS DILOBOPTERUS COSTALIMAI AND ONCOMETOPIA FACIALIS (HEMIPTERA: CICADELLIDAE), VECTORS OF THE CITRUS VARIEGATED CHLOROSIS (CVC)

Dilobopterus costalimai (Young) and Oncometopia facialis (Signoret) are two of the most important species of citrus leafhoppers, vectors of bacterium Xylella fastidiosa which causes the Citrus Variegated Chlorosis (CVC) disease.To develop a rearing technique for these species under laboratory conditions, the egg laying preference and nymph developm

BackgroundTumour suppressor genes are often transcriptionally silenced by promoter hypermethylation, and recent research has implicated alterations in chromatin structure as Pillow the mechanistic basis for this repression.In addition to DNA methylation, other epigenetic post-translational modifications that modulate the stability and binding of sp

Interleukin 4 (IL-4) induces B-cell differentiation and survival of chronic lymphocytic leukemia (CLL) cells.MicroRNAs (miRNAs) regulate mRNA and protein expression, and several miRNAs, deregulated in CLL, might play roles as oncogenes or tumor suppressors.We have studied the miRNA profile of CLL, and its response to IL-4, by oligonucleotide microa
