The Role of Plant Hormones in Nematode Feeding Cell Formation

Chapter

Abstract

In this Chapter, we discuss recent advances in the role of plant hormones in the molecular mechanisms underlying feeding cell formation both by cyst (CN) and root-knot nematodes (RKN). Phytohormones are small signalling molecules that regulate plant growth and development, including the formation of highly specialized root structures like nematode feeding cells. High-throughput transcriptome profiling has facilitated the identification of an increasing number of novel hormone related genes that are differentially expressed during feeding cell development. Together with dedicated functional studies, a picture has emerged which points to plant hormones playing an important role in the reprogramming of gene expression patterns upon nematode infection. Here, we present a comprehensive overview of the role of classical plant hormones, including cytokinin, auxin and ethylene, in the establishment of nematode-induced regulatory networks upon infection of plant roots. We also discuss the role of small peptides as a novel class in plant hormone signalling during feeding cell formation.
