The genome of Azoarcus olearius DQS-4T , a N2 -fixing Betaproteobacterium isolated from oil-contaminated soil in Taiwan, was sequenced and compared with other Azoarcus strains. The genome sequence showed high synteny with Azoarcus sp. BH72, a model endophytic diazotroph, but low synteny with five non-plant-associated strains (Azoarcus CIB, Azoarcus EBN1, Azoarcus KH32C, A. toluclasticus MF63T and Azoarcus PA01). Average Nucleotide Identity (ANI) revealed that DQS-4T shares 98.98% identity with Azoarcus BH72, which should now be included in the species A. olearius. The genome of DQS-4T contained several genes related to plant colonization and plant growth promotion, such as nitrogen fixation, plant adhesion and root surface colonization. In accordance with the presence of these genes, DQS-4T colonized rice (Oryza sativa) and Setaria viridis, where it was observed within the intercellular spaces and aerenchyma mainly of the roots. Although they promote the growth of grasses, the mechanism(s) of plant growth promotion by A. olearius strains is unknown, as the genomes of DQS-4T and BH72 do not contain genes for indole acetic acid (IAA) synthesis nor phosphate solubilization. In spite of its original source, both the genome and behaviour of DQS-4T suggest that it has the capacity to be an endophytic, nitrogen-fixing plant growth-promoting bacterium. |

Maté (Ilex paraguariensis A. St. Hil.) is a shade-tolerant species, frequently cultivated on agroforestry systems or even in monoculture. Secondary metabolism of mate´ includes the methylxanthines, caffeine and theobromine. Shading could alter the quantitative profile of these compounds in the plant, and since the secondary chemistry of maté is decisive to determine the quality of raw material, the caffeine and theobromine content under different light intensities were investigated. Artificial shading obtained by a nylon screen and natural shading produced by other trees were tested. Methylxanthines content was increased with the reduction of light, but only in the low light intensity treatment. A negative correlation was found between biomass accumulation and methylxanthines content. But the total methylxanthines yield per plant was not altered. |
