Abstract:
Plant-associated fungi often present in their genome areas enriched in repeat sequences and effector genes, the latter being specifically induced in planta. The location of effector genes in regions enriched in repeats has been shown to have an impact on adaptability of fungi but could also provide for tight control of effector gene expression through chromatin-based regulation. The distribution of two repressive histone marks was shown to be an important regulatory layer in two fungal species with different lifestyles. Chromatin-based control of effector gene expression is likely to provide an evolutionary advantage by preventing the expression of genes not needed during vegetative growth and allow for a massive concerted expression at particular time-points of plant infection.

The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
