Vitamin B12 (B12) is produced only by prokaryotes (Fang et al., 2017), but is also widely required among eukaryotes as an enzymatic cofactor. In the green lineage, the only B12-dependent enzyme is methionine synthase. Several green algae can synthesize methionine only thanks to B12 provided by mutualistic…

Plants produce a plethora of specialized metabolites serving as a chemical arsenal against abiotic and biotic challenges during their lifetime. Core metabolites serve as building blocks for diverse decorating enzymes like oxidases, reductases or transferases that introduce new functionalities expanding…

Michael J. Skelly [email protected] To ensure optimal growth and development, plants must precisely control gene expression networks in a tissue-specific manner. MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that post-transcriptionally silence genes by binding to complementary…
