Cytochromes P450 evolution in the plant terrestrialization context.

Plants started to colonize land around 500 million years ago. It meant dealing with new challenges like absence of buoyancy, water and nutrients shortage, increased light radiation, reproduction on land, and interaction with new microorganisms. This obviously required the acquisition of novel functions and metabolic capacities.

Promiscuity, a Driver of Plant Cytochrome P450 Evolution?

Plant cytochrome P450 monooxygenases were long considered to be highly substrate-specific, regioselective and stereoselective enzymes, in this respect differing from their animal counterparts. The functional data that have recently accumulated clearly counter this initial dogma. Highly promiscuous P450 enzymes have now been reported, mainly in terpenoid pathways with functions in plant adaptation, but also some very versatile xenobiotic/herbicide metabolizers.

Plant cytochrome P450 plasticity and evolution.

The superfamily of cytochrome P450 (CYP) enzymes plays key roles in plant evolution and metabolic diversification. This review provides a status on the CYP landscape within green algae and land plants. The 11 conserved CYP clans known from vascular plants are all present in green algae and several green algae-specific clans are recognized.

Toward a Systematic Nomenclature for (Neo)Lignanamides.

Phenylalkenoic acid amides, often referred to as phenol amides or hydroxycinnamic acid amides, are bioactive phytochemicals, whose bioactivity can be enhanced by coupling to form dimers or oligomers. Phenylalkenoic acid amides consist of a (hydroxy)cinnamic acid derivative (i.e.
