Представители рода Pantoea положительно влияют на рост и развитие растений. В геноме штамма P. brenneri 3.5.2 выявлены гены и генетические кластеры, отвечающие за их множественные PGP-свойства, подтвержденные ранее биохимическими и микробиологическими методами. Штаммы способны к гидролизу почвенных фитатов, а также проявляют активность в отношении неорганических почвенных фосфатов: гидроксиапатита, фосфорита и трикальцийфосфата. Обнаружены гены gcd и pqqE, отвечающие за продукцию глюконовой кислоты, участвующей в процессах мобилизации фосфора. При росте на средах с различными источниками недоступного фосфора штаммы P. brenneri были способны к секреции кислой и щелочной фосфатаз, активность которых зависела от времени культивирования бактерий и источника фосфата в среде.
