[Abstract]  The spatio-temporal expression pattern of a gene provides important indications to better understand its biological function. In situ hybridization (ISH) uses a labeled complementary single-stranded RNA or DNA probe to localize gene transcripts in a whole organism, a whole organ or a section of tissue. We adapted the ISH technique to the plant parasite Meloidogyne spp. (root-knot nematode) to visualize RNAs both in free-living preparasitic juveniles and in parasitic stages settled in the plant tissues. We describe each step of the probe synthesis, digoxigenin (DIG) labeling, ... [摘要]  基因的时空表达模式为更好地理解其生物学功能提供了重要的指示。 原位杂交(ISH)使用标记的互补单链RNA或DNA探针来定位整个生物体,整个器官或一部分组织中的基因转录物。 我们将ISH技术应用于植物寄生虫

【背景】到目前为止,植物寄生性线虫的稳定转化尚未成功。 ISH能够在整个装载的Meloidogyne spp中分析体内时空基因表达。线虫。这些根结线虫在土壤中以微小蚓状幼虫(J2)形式孵化并感染宿主植物根部。 J2s穿透根部并迁移到根部维管柱状细胞。幼虫定居在根部,发育成J3和J4寄生幼鱼,诱导分化专化饲养细胞。线虫最终发育成梨形雌性,将在根表面释放数百个卵。在这里,我们报告了一个详细的协议来检测准备性整体安装J2s和寄生阶段中的单个RNA分子。寄生虫阶段的ISH需要在感染根部提取线虫前一天采取额外的程序。我们描述了在线虫整个组织中使用地高辛(DIG)标记的cDNA探针检测转录物。
