Project description:Genome sequence of a novel Pigmentiphaga species isolated from soil continously amended with humic acid
| PRJEB29162 | ENA
Project description:Humic substances are principal components of soil organic matter. They have ecological importance as they intervene in regulating a large number of chemical and biological processes that occur in natural ecosystems. Their ability to improve plant growth has been well established in diverse plant species and growth conditions, although the mechanism responsible for this biological action is poorly understood. Microarray analysis might give us more information about up or down regulation of different biological processes. Wheat plants have been grown hydroponically and treated with Humic acid. Seeds were germinated in obscurity during 10 days, and grown in nutrient solution during 10 days. Harvests were conducted 24 hours, 72 hours and 30 days after treatment application, in order to study early response or a more sustained effect during time.

Project description:Soil humic substances are known to positively influence plant growth and nutrition. In particular, low-molecular fractions have been shown to increase NO3- uptake and PM H+-ATPase activity and alter expression of related genes. Changes in maize root transcriptome due to treatment with nitrate (NO3-), Water-Extractable Humic Substances (WEHS) and NO3-+WEHS were analyzed.

Project description:This study began with 72 male 4-week-old BALB/c mice. The mice were split evenly into one of four cohorts: Control, River, Pine, and Road. The control mice were raised with standard corn cob bedding whereas the remaining mice were raised with clean bedding amended with 300 mL of one of three different types of soil. The soil exposure continued throughout the experiment, with 300 mL of new soil added with bi-weekly cage changes. The soils used to amend the cage bedding were previously characterized as having high (Pine), medium (River), and low (Road) diversity. The River and Pine soil were collected from Duke Forest and the Road soil was collected adjacent to Highway 15-501 in Chapel Hill, North Carolina. All mice were given a standard diet and the cages were distributed reverse osmosis treated water through a centralized Lixit® system that was fed to each cage in parallel. After 32 days of standard rearing with amended soils, the mice were exposed via oropharyngeal aspiration to either live influenza A (PR8) virus or heat inactivated (HI) virus.

Project description:Genome-wide microarray analysis was performed using RNA extracted from soil cultures of Streptomyces coelicolor A3(2) in the presence or absence of chitin. The vast majority of genes in chitin and amino sugar metabolism, as well as many other genes for carbon and energy, nitrogen and sulfur metabolism, were differentially expressed in response to addition of chitin. Moreover, the gene expressions of eight gene clusters for secondary metabolites were also significantly up-regulated in the chitin amended soil. To reveal the role of a pleiotropic transcriptional regulator, DasR, which has been reported to be involved in regulation of chitin metabolism, antibiotic production and morphological differentiation, the gene expression patterns of wild type and dasR mutant in soil amended with chitin were compared by microarray analysis. The dasR mutation resulted in up-regulation of four antibiotic gene clusters and down-regulation of chitin metabolism.

A study using total RNA extracted from soil cultures of Streptomyces ceolicolor A3(2). A whole genome microarray of S. coelicolor (NimbleGen Custom Prokaryotic Gene Expression 72K 4-plex Arrays) was designed and manufactured by Roche (Roche NimbleGen, Madison, WI). Each array contained four sets of 8 sequence-specific 60-mer probes per gene corresponding to 7825 genes from the S. coelicolor A3(2) genome.
