The cnidarian Nematostella vectensis has become an established lab model, providing unique opportunities for venom evolution research. The Nematostella venom system is multimodal: involving both nematocytes and ectodermal gland cells, which produce a toxin mixture whose composition changes throughout the life cycle. Additionally, their modes of int...

Because of their symbiotic origin, many mitochondrial proteins are well conserved across eukaryotic kingdoms. It is however less obvious how specific lineages have obtained novel nuclear-encoded mitochondrial proteins. Here, we report a case of mitochondrial neofunctionalization in plants. Phylogenetic analysis of genes containing the Domain of Unk...

Over several decades, glucosinolates have become a model system for the study of specialized metabolic diversity in plants. The near-complete identification of biosynthetic enzymes, regulators, and transporters has provided support for the role of gene duplication and subsequent changes in gene expression, protein function, and substrate specificit...

Organisms throughout the natural world have evolved different methods for biosynthesis of natural products, utilized in their native environs for defense, structure and signaling. One such method is the employment of modular polyketide synthase and non-ribosomal peptide synthetase enzymes to produce molecules from acetate and amino acid building bl...

The realization that body parts of animals and plants can be recruited or coopted for novel functions dates back to, or even predates the observations of Darwin. S.J. Gould and E.S. Vrba recognized a mode of evolution of characters that differs from adaptation. The umbrella term aptation was supplemented with the concept of exaptation. Unlike adapt...
Crop diseases caused by fungi constitute one of the most important problems in agriculture, posing a serious threat to food security [1]. To establish infection, phytopathogens interfere with plant immune responses [2, 3]. However, strategies to promote virulence employed by fungal pathogens, especially non-model organisms, remain elusive [4], main...
