CBL2-CIPK6-TST2-mediated regulation of sugar homeostasis

Sugars have a key role in numerous cellular processes, and thus their storage and distribution are tightly controlled to ensure appropriate access when needed. In plants, the vacuole is the major storage organelle. The tonoplast (vacuole membrane) contains various transporters that regulate sugar and…

Overcoming Algal Vitamin B12 Auxotrophy by Experimental Evolution

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…

Sulfotransferase 1 is the enzymatic hub of sulfated salicinoids in poplar.

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…
