Genome survey sequencing (1.9X coverage) was generated for Moniliophthora perniciosa, the cause of witches’ broom disease on cacao plants. The sequence for this basidiomycete plant pathogen was published in BMC Genomics this week. The authors report a higher number of ROS metabolism and P450 genes. Evaluating whether these copy number differences are significantly different from other basidiomycete fungi and are lineage specific expansions will help determine if these families played a role in the adaptation of this plant pathogen.
This work provides an important stepping stone in understanding and eventually controlling this pathogen which is devastating cacao plantations. An associated review describes what we have and can learn about Witches’ broom disease.
