Abstract

Rhizobium leguminosarum biovar viciae and Rhizobium leguminosarum biovar trifolii have separate uptake systems for 4-hydroxybenzoate and protocatechuate. The 4-hydroxybenzoate uptake system (pobP) is inhibited by a range of compounds with substitution at the 4-position on the aromatic ring whereas the uptake system for protocatechuate (pcaP) is markedly inhibited only by other dihydroxybenzoic acids. The rate of 4-hydroxybenzoate uptake is very low in Rhizobium leguminosarum and Rhizobium trifolii grown on protocatechuate but mutants defective in 4-hydroxybenzoate uptake transport protocatechuate at rates similar to the wild-type grown under similar conditions.
