MeSH headings : Animals; Cell Wall / metabolism; Cysts / metabolism; Gene Expression Regulation, Plant / genetics; Giant Cells / cytology; Infections; Microscopy, Confocal / methods; Nematoda / metabolism; Nematode Infections / metabolism; Nematode Infections / physiopathology; Plant Diseases / parasitology; Plant Roots / metabolism; Plant Roots / parasitology; Triticum / metabolism; Triticum / parasitology; Tylenchoidea / parasitology; Tylenchoidea / physiology; Xylem / cytology

TL;DR: By interfering with a developmental program that normally leads to programmed cell death, H. avenae may permit xylem vessel elements to remain alive for later exploitation by the parasite. (via Semantic Scholar)
