Abstract
Soil microorganisms respond to, and release signals in, the rhizosphere, affecting root growth and their interactions with parasites. Understanding the gene expression patterns that are active in roots is fundamental for successful exploitation of beneficial associations. Pochonia chlamydosporia is a facultative parasite of nematode eggs and a growth-promoting endophyte. Transcriptomic studies from roots colonized by P. chlamydosporia showed that the fungus differentially regulates several genes. These included transcription factors and microRNAs differentially expressed during root endophytism. Both are transcriptional regulators and form integral parts of signalling webs, modulating many biological processes. The transcription factors involved in defence, resistance and plant growth include WRKYs, a family of genes expressed either in P. chlamydosporia-colonized or control roots. In vitro studies on endophytism also showed differential expression of 26 miRNAs, with 154 potential target genes involved in apoptosis, metabolism and binding, including transcription factors. The differential gene expression induced by P. chlamydosporia in the presence of nematodes or other pathogens may disclose novel pest and disease management strategies. The fungus transcriptomic analyses also support the production of industrial and commercial bioformulations for plant protection, through the induction of endogenous plant defence mechanisms.
