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: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.

Project description:In this study a transcriptomic approach (RNA-sequencing) was utilized to elucidate molecular responses of maize (Zea mays L.) primary roots of the inbred line B73 to water deficit to gain a better understanding of the mechanisms underlying drought tolerance. Kernels of the maize inbred line B73 were germinated in paper rolls soaked with distilled water until seedlings had a primary root length of 2 to 4 cm. For mild and severe water deficit conditions, seedlings were transferred to PEG8000 solution with water potentials of -0.2 MPa and -0.8 MPa, respectively. Water deficit treatment was applied for 6 h and 24 h. Each treatment was performed in four biological replicates each consisting of 10 roots.
