Project description:Cadmium treatment induces slow but long lasting nitric oxide production in plant tissues. This NO production can be suppressed using the commonly used Nitric Oxide Synthase inhibitor L-NAME. This inhibitor tends to partially alleviate Cd toxicity. This effect is correlated with a strong diminution of Cd content in roots of plants treated both with Cd and L-NAME compared to roots from plants treated with Cd only. The main goal of this study is the identification of transcriptionnal changes caused by Cd-induced nitric oxide, and that could potentially result in enhanced Cd root accumulation.

After 2 weeks, the young plantlets were placed on sand for an additional 3 week period in a controlled environment (8 h photoperiod of 300 umol m-2 s-1, 22degreeC, 70% relative humidity) . Plants of similar rosette diameters were then transfered to an hydroponic culture using the nutritive solution described in [Gravot et al. 2004 FEBS Letters 561:22-28] for an acclimation of 3 days. L-NAME and cadmium treatments were respectively started 1 and 2 hours after the start of illumination and root tissues were collected 24 h later and immediatly frozen in liquid nitrogen before RNA extraction. Treatments were : 1 : control 2 : L-NAME 5 mM 3 : Cd 30 uM 4 : L-NAME 5mM + Cd 30 uM 5 : Cd 15 uM For each condition, 3 independent biological repetitions were conducted. RNA were extracted separatly and checked for quality before pooling together. Keywords: treated vs untreated comparison

Project description:In this study, we used RNA-Seq to understand the mechanisms of Cd toxicity, cellular detoxification and protection pathways in response to Cd in rice roots. To gain additional insight into the rice transcriptomic response to environmental Cd stress, 15-day-old rice seedlings were treated with 10 or 100 μM solutions of Cd2+, or without Cd (control), for 24 h, at which point root samples were harvested and labeled as Cd+, Cd++, and control, respectively. These samples were used for 101 bp paired-end (PE) deep sequencing on an Illumina HiSeq 2500 platform.

Project description:We examined the effect of galactoglucomannan oligosaccharides (GGMOs) and/or Cd on the activity of peroxidases and the proteome of maize (Zea mays L.) roots and leaves. Our previous work confirmed that the application of GGMOs ameliorates symptoms of Cd stress in plants. Here, the plants were cultivated in hydroponics for 7 days, and the protein levels and peroxidase activity were estimated in intracellular, basic cell wall, and acidic cell wall protein fractions. The activity of peroxidases varied between the plant organs, as well as among the fractions and treatments. The application of GGMOs on plants suffering from Cd stress did not significantly influence the levels of peroxidases but modulated their activity, which implies posttranslational regulation. Next, we focused on the characterisation of proteins with significant changes in their levels in the GGMOs + Cd treatment. The changes in the level of various proteins (e.g., related to the defence reactions, cell wall structure/metabolism, and activation of plant hormones) caused by GGMOs and Cd presence suggested possible mechanisms of action of these oligosaccharides, which improve vitality of maize seedlings exposed to Cd.

Project description:The total RNA were extracted from tissues of roots from several plants of Panax notoginseng under CK and Cd stress treatment by using TRIzol reagent (Invitrogen) according to the manufacturer's instructions. The purified PCR product was sequenced using Illumina Genome Analyzer II. The qualified reads were used to study of Panax notoginseng transcriptome under CK and Cd stress treatment.

Project description:To massively identify genes that are up-regulated by Cd and in particular transporter genes which might transport peptides or oligopeptides. Four week old hydroponically-grown Col-0 plants were treated with/without 200uM Cd for 6 hours. Total RNA was extracted from roots and subjected to hybridization with Affymetrix ATH1 microarrays.

Project description:Cd levels in the shoots, as well as in the roots were unexpectedly reduced in 35S:AtHMA4-expressing tobacco. Obtained results indicate that in the generation of the Cd-related phenotypes of transgenic plants substantial modifications of the host plant transcriptome was involved. Microarray based analysis was performed to compare expression profiles of the roots from tobacco expressing 35S-AtHMA4 with the wild-type (WT) plants, which were grown in the presence of 0.25 µM Cd. An effort was undertaken to understand which processes were modified in tobacco as a result of the expression of 35S:AtHMA4, which lead to decreased Cd uptake and lower accumulation in the shoots. Knowing underlying mechanisms is important for developing strategies to grow low cadmium tobacco.
