Key Findings
50x citrate/malate secretion in cluster roots
23 novel exudate compounds identified
2 new flavonoids enhance microbial phosphatase
Original Abstract
White lupin cluster roots secrete citrate and malate at rates 50x higher than non-cluster roots. Metabolomic profiling identified 23 novel exudate compounds under P-deficiency, including two previously unknown flavonoids that enhance microbial phosphatase activity.
