The thaxtomin phytotoxins (1 and 2) from scab-producing Streptomyces pathogens of the potato are 2,5-dioxopiperazines consisting of modified l-tryptophanyl and l-phenylalanyl units. Thaxtomin A (1) is hydroxylated at C-14, the alpha carbon of the mod

Evidence for the involvement of a bacterial nitric oxide synthase (NOS) in the biosynthesis of a phytotoxin is presented. Several species of Streptomyces bacteria produce secondary metabolites with unusual nitrogen groups, such as thaxtomin A (ThxA),

Potato scab is a globally important disease caused by polyphyletic plant pathogenic Streptomyces species. Streptomyces acidiscabies, Streptomyces scabies and Streptomyces turgidiscabies possess a conserved biosynthetic pathway for the nitrated dipept

Nitric oxide (NO) is a potent intercellular signal in mammals that mediates key aspects of blood pressure, hormone release, nerve transmission and the immune response of higher organisms. Proteins homologous to full-length mammalian nitric oxide synt

The biosynthesis of the thaxtomin cyclic dipeptide phytotoxins proceeds nonribosomally via the thiotemplate mechanism. Acyladenylation, thioesterification, N -methylation, and cyclization of two amino acid substrates are catalyzed by the txtAB -encod

Four Streptomyces species have been described as the causal agents of scab disease, which affects economically important root and tuber crops worldwide. These species produce a family of cyclic dipeptides, the thaxtomins, which alone mimic disease sy

Several Streptomyces species cause plant diseases, including S. scabies, S. acidiscabies and S. turgidiscabies, which produce common scab of potato and similar diseases of root crops. These species produce thaxtomins, dipeptide phytotoxins that are r

Some dynamic aspects of leaf elongation in rice were studied. Under both well watered and water-deficient conditions, leaf elongation rates were 15 to 30% greater during the day than during the night. Night temperatures below 27 C limited the rate of
