Correction for Heal et al., “Marine Community Metabolomes Carry Fingerprints of Phytoplankton Community Composition”

Volume 6, no. 3, e01334-20, 2021, https://doi.org/10.1128/mSystems.01334-20. After publication, we discovered that the authentic standard of homarine that we purchased from a commercial supplier (Santa Cruz Biotechnology, lot B1916) was contaminated with picolinic acid. This contamination resulted in an overstatement of the actual homarine concentration in these samples. The correct values for the homarine concentration are 1/25 of the previously published values. This correction is based on a comparison of our original standard with both a commercially purchased isotope labeled standard and a newly purchased homarine standard. The recalculated values for homarine are reflected in the corrections below.
