additional information (R)-beta-tyrosine occurs in the seeds, leaves, roots, and root exudates of the Nipponbare cultivar. Dry rice seeds from plants that have not been elicited with jasmonic acid also contain significant amounts of beta-tyrosine. When rice seedlings are grown hydroponically, beta-tyrosine is secreted into the medium Oryza sativa Japonica Group

Oryza sativa Japonica Group hemipteran and lepidopteran herbivores show no negative effects at physiologically relevant beta-tyrosine concentrations additional information
Oryza sativa Japonica Group beta-tyrosine accumulation is induced by the plant defense signaling molecule jasmonic acid, jasmonic acid treatment of the seedlings increases beta-tyrosine content in the leaves, roots, and imbibed seed material. up

General Information

General Information Comment Organism
malfunction rice cultivars that do not produce beta-tyrosine have a chromosome 12 deletion that encompasses TAM1 Oryza sativa Japonica Group
additional information hemipteran and lepidopteran herbivores show no negative effects at physiologically relevant beta-tyrosine concentrations Oryza sativa Japonica Group
physiological function tyrosine aminomutase TAM1 is required for beta-tyrosine biosynthesis in Oryza sativa, the tyrosine aminomutase converts the common protein amino acid tyrosine (alpha-tyrosine) into beta-tyrosine. beta-Tyrosine is most prevalent in temperate japonica cultivars. beta-Tyrosine is exuded into hydroponic medium at higher concentrations and may contribute to the allelopathic potential of rice. Pseudomonas syringae growth is inhibited by beta-tyrosine, and seedlings of dicot species are much more sensitive to exogenous beta-tyrosine than rice and other tested monocots Oryza sativa Japonica Group
