Abstract

Sordaria sp. has been a model for study of fruiting-body differentiation in fungi. Several environmental factors, including light, affect cellular and morphological changes during multicellular tissue development. Here, we created a light-oxygen-voltage-sensing (LOV) domain-deleted Sfwc-1 mutant to study blue-light photoresponses in Sordaria fimicola . Phototropism and rhythmic zonation of perithecia were defective in the Sfwc-1 ( Δlov ) mutant. Moreover, fruiting-body development in the mutant was reduced and also significantly delayed. Gene expression analysis and subcellular localization study further revealed the light-induced differential gene expression and cellular responses upon light stimulation in S. fimicola .
