Phosphoenolpyruvate carboxylase activation by reversible phosphorylation in white lupin cluster roots
Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated enzyme that controls carbohydrate partitioning to organic acid anions (malate, citrate) that are excreted in copious amounts by cluster

Linkage between leaf traits and vegetation zonation
A high nitrogen content per leaf area (Narea) induced by drought can enhance water use efficiency (WUE), but may also increase leaf construction cost (CC). Wei

Aminotransferases provide the signals for root growth
Uncovering the role of new aminotransferases in the regulation of the signals behind root growth, Le Deunff et al. show that L-aminoethoxyvinylglycine (AVG) acts as
