In a compatible interaction, root-knot nematodes (Meloidogyne) induce a sophisticated feeding site shortly after they have penetrated the plant root. The feeding site contains metabolically highly active giant cells. To gain insight into the molecular aspects that are typical for giant cells, a cDNA library from tomato roots infected with Meloidogyne incognita was differentially screened to find induced genes. Among the genes identified, two extensin genes (Lemmi8 and Lemmi11) and a Lea-like gene (Lemmi9) were studied further.
在亲和互作中，根结线虫（Meloidogyne）在侵入植物根系后不久便诱导形成一个复杂的取食位点。该取食位点包含代谢高度活跃的巨型细胞。为深入了解巨型细胞特有的分子层面情况，对感染南方根结线虫的番茄根系的cDNA文库进行了差异筛选，以寻找诱导基因。在鉴定出的基因中，对两个伸展蛋白基因（Lemmi8和Lemmi11）和一个类Lea基因（Lemmi9）进行了进一步研究。
