Recurring heat waves affect DNA methylation to reduce respirational losses, enhancing heat tolerance Arabidopsis thaliana [RNA-seq]

ABSTRACT: we investigated the effect of exposing 4 successive generations of Arabidopsis thaliana to severe heatwave conditions. We show that heat-primed offspring has increased survival rates and seed production after exposure to heat wave conditions. Bisulfite sequencing allowed us to link this to altered DNA methylation, including a global hypomethylation of the mitochondrial DNA. mRNA sequencing showed that priming affected genes related to the mitochondrial energy system and oxidative stress responses.

Heat stress in 7 Solanaceae species, replicate 1 and 2

Project description:Seven different Solanaceae species, Potato (Solanum tuberosum), Tomato (Solanum lycopersicum), Eggplant (Solanum melongena), Pepper (Capsicum annuum), Tobacco (Nicotiana tabacum), Petunia and Nicotiana benthamiana were subjected to heat stress. Plants were grown for 4-6 weeks at 25 C after which heat stress was initiated by exposing the plants to 35 C for 6, 12, 24, 48 and 96 hours. Control samples were isolated from plants just before initiating the heat stress. RNA was isolated using Qiagen RNeasy. Keywords: Direct comparison

Project description:BackgroundMany studies have linked weather to mortality; however, role of such critical factors as regional variation, susceptible populations, and acclimatization remain unresolved.MethodsWe applied time-series models to 107 US communities allowing a nonlinear relationship between temperature and mortality by using a 14-year dataset. Second-stage analysis was used to relate cold, heat, and heat wave effect estimates to community-specific variables. We considered exposure timeframe, susceptibility, age, cause of death, and confounding from pollutants. Heat waves were modeled with varying intensity and duration.ResultsHeat-related mortality was most associated with a shorter lag (average of same day and previous day), with an overall increase of 3.0% (95% posterior interval: 2.4%-3.6%) in mortality risk comparing the 99th and 90th percentile temperatures for the community. Cold-related mortality was most associated with a longer lag (average of current day up to 25 days previous), with a 4.2% (3.2%-5.3%) increase in risk comparing the first and 10th percentile temperatures for the community. Mortality risk increased with the intensity or duration of heat waves. Spatial heterogeneity in effects indicates that weather-mortality relationships from 1 community may not be applicable in another. Larger spatial heterogeneity for absolute temperature estimates (comparing risk at specific temperatures) than for relative temperature estimates (comparing risk at community-specific temperature percentiles) provides evidence for acclimatization. We identified susceptibility based on age, socioeconomic conditions, urbanicity, and central air conditioning.ConclusionsAcclimatization, individual susceptibility, and community characteristics all affect heat-related effects on mortality.

Entamoeba heat shock experiments

Project description:Entamoeba histolytica is a protozoan parasite which causes colitis and liver abscesses. A pilot microarray consisting of 360 unique parasite genes was constructed using identical methods to the larger array (1,971 unique genes). The four arrays in this data set were used to ascertain whether the microarrays would be useful in detecting changes in transcript abundance by exposing parasites to heat shock (42 0C for 1 hr). Approximately, 17% of the genes were regulated by at least two fold including many genes previously shown to be involved in heat shock response. This data confirmed that the genomic DNA arrays were useful in detecting changes in transcript abundance. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set
