Trehalose biosynthesis is involved in sporulation of Stagonospora nodorum.

Stagonospora nodorum is a necrotrophic fungal pathogen that is the causal agent of leaf and glume blotch on wheat. S. nodorum is a polycyclic pathogen, whereby rain-splashed pycnidiospores attach to and colonise wheat tissue and subsequently sporulate again within 2-3weeks.

A metabolomic approach to dissecting osmotic stress in the wheat pathogen Stagonospora nodorum.

A non-targeted metabolomics approach was used to identify significant changes in metabolism upon exposure of the wheat pathogen Stagonospora nodorum to 0.5M NaCl. The polyol arabitol, and to a lesser extent glycerol, was found to accumulate in response to the osmotic stress treatment.
