ABSTRACT: Theobroma cacao seeds were oven dried at 50 C and ground in an analytical mill. The ground seeds were extracted with propylene glycol in the ratio of 20:80 W/V.

Project description:Transcriptomic study of the impact of osmopriming on rape seeds (Brassica napus L.; cv 'Libomir') during priming process and after germination. The assays were replicated twice on two independent priming and germination experiments. Seeds were osmoprimed in PEG solution (-1.2 MPa osmotic potential) during 7 days, dried to initial moisture content and then germinated for 7 hours on water. The analysis during different phases of priming procedure (soaking and drying), after whole osmopriming process and germination were done. 10 samples, four condition experiment; non dried primed seeds (Pnd) vs. dry unprimed seeds (UPd) (PEG soaking), non dried primed seeds (Pnd) vs dry primed seeds (Pd) (drying after soaking), dry primed seeds (Pd) vs. dry unprimed seeds (UPd) (full osmopriming process), primed seeds imbibed on water (P7h) vs unprimed seeds imbibed on water (UP7h) (germination after osmopriming). Biological replicates: 2 replicates for comparison PEG soaking, drying after soaking, full osmopriming process and germination after osmopriming.
Project description:affy_ath_2012_04 - affy_ath_2012_04 - Epigenetic informations include histone post-translational modifications such as acetylation and methylation. The jumoni proteins can remove the methyl group from lysine or arginine residues of histones. The aim of this project is to compare gene expression levels between mutants of two jumonji genes and wild type at seedling stage (12 d old).-- Seeds were sterilized in bleach, washed with ethanol, dried, dispersed on Murashige and Skoog (MS) 0.5X containing 2% sucrose and kept 5 days at 4°C. - After 12 days of growth under a cool white fluorescent light (120 μmol m-2 s-1) and long day conditions (16h of light) in a growth chamber, the plants are harvested and stored at -80°C. -The RNA are extracted with the RNA Plant NucleoSpin (Machery-Nagel), quantified with Nanodrop and visualised on agarose gel. The samples are stored at -80°C.

Project description:The study used two Drosophila melanogaster fly lines, Alstonville and Dahomey, which have mitochondrial DNA variants but otherwise similar genomes. Female third instar larvae from both lines were fed on two diets, one with a 1:2 protein:carbohydrate ratio and the other with a 1:16 ratio. RNA was extracted and profiled by RNA-seq. Samples were sequenced on an Illumina Hiseq 2000 sequencer at the Ramaciotti Centre for Genomics, Sydney, Australia to produce 100bp paired end reads. At least 80 million read pairs were generated per sample.
Project description:au15-04_xeno - transcriptomic analysis of the effects of low levels of atrazine and by-products - Identification of xenobiotic direct sensing and of low chemical stress transduction networks in Arabidopsis thaliana. - Seeds of Arabidopsis thaliana (Columbia ecotype, Col-0) were surfaced-sterilized in bayrochlore/ethanol (1/1, v/v), rinsed in absolute ethanol and dried overnight. Germination and growth were carried out under axenic conditions in square Petri dishes. After seeds were sowed, Petri dishes were placed in the dark at 4 °C for 72 h in order to break dormancy and homogenize germination, and were then transferred to a control growth chamber at 22 °C/20 °C under a 16 h light (6000 lux)/8 h dark regime. Growth medium consisted of 0.8% (w/v) agar in Hoagland basal salt mix (H2395, Sigma-Aldrich) adjusted to pH 6. After 13 days of growth under optimal conditions, seedlings were transferred to fresh growth medium containing pesticides during 24 h (Control, Atrazine 1µM, Hydroxyatrazine 1µM or Desethylatrazine 1µM). Then control and treated seedlings were harvested and ground in liquid nitrogen until RNA extraction by RNeasy kit (Qiagen) and DNase digestion. RNA was extracted on at least 2 independent biological replicates of 30 pooled plantlets.
Project description:The development of Col-0 and WS plants on orbit differs from that on the ground as demonstrated by the comparison of the gene expression profiles between 4 days old to 8 days old plant in the two environments. The Col-0 plants used different genes reflecting different physiological processes than WS plants, suggesting the role of the genetic background in the developmental decisions. The 4 days old Col-0 plant in orbit showed deficit in wax and suberin production relatively to the 8 days old plants, the difference unregistered on the ground. There was more dramatic difference in the overexpression of the root system development and anatomical structure development genes in 8 days old plants than in 4 days old plant in both genotypes on the ground than in flight, implying smaller root developmental gap between 4 days and 8 days old roots in orbit. The WS plant uniquely showed overexpression of the photosynthesis related genes in the 4 days old roots relative to 8 days old root in the spaceflight environment but not on the ground. The seeds germinated in the novel growth environment of ISS implemented different developmental strategies as captured by the genes expression patterns, than seeds developing on the ground.
Project description:Moniliophthora perniciosa is the causal agent of cacao Witche´s broom disease. This disease has been causing extensive damages to Brazilian cacao plantation, especially in Southern Bahia. Using glass slides microarrays, we analyzed the expression profile of 3872 whole genome shotgun reads from M. perniciosa genome, comparing two stages of development (Biotrophic-like mycelia and saprotrophic mycelia).
