1. Resistance of potato cultivars (Solanum tuberosum) to common scabies (Streptomyces spp.) and action mechanism of the phytotoxin thaxtomin A in sorghum (Sorghum bicolor): biochemical and ultrastructural aspects / Resistência de cultivares de batata (Solanum tuberosum) à sarna comum (Streptomyces spp.) e mecanismo de ação da fitotoxina taxtomina A em sorgo (Sorghum bicolor ): aspectos bioquímicos e ultraestruturais
O gênero Streptomyces constitui-se em um grupo diferenciado de procariotos fitopatogênicos, por serem morfologicamente similares aos fungos e produzirem diversos importantes metabólitos secundários. A sarna comum da batata é principal doença causada pelo gênero. O principal agente causal da doença, Streptomyces scabies, produz fitotoxinas denominadas

2. Selection and Characterization of Microorganisms Utilizing Thaxtomin A, a Phytotoxin Produced by Streptomyces scabies
Thaxtomin A is the main phytotoxin produced by Streptomyces scabies, a causal agent of potato scab. Thaxtomin A is a yellow compound composed of 4-nitroindol-3-yl-containing 2,5-dioxopiperazine. A collection of nonpathogenic streptomycetes isolated from potato tubers and microorganisms recovered from a thaxtomin A solution were examined for the ability to gr

3. An Arabidopsis Mutant Resistant to Thaxtomin A, a Cellulose Synthesis Inhibitor from Streptomyces SpeciesW⃞
Thaxtomin A is a phytotoxin produced by Streptomyces scabies and other Streptomyces species, the causative agents of common scab disease in potato and other taproot crops. At nanomolar concentrations, thaxtomin causes dramatic cell swelling, reduced seedling growth, and inhibition of cellulose synthesis in Arabidopsis. We identified a mutant of Arabidopsis,
