Project description:Salt cress (Eutrema salsugineum, synonymously Thellungiella salsuginea) is an extremophile, a close relative of Arabidopsis. In order to understand the selective mechanisms that shape their complex traits underlying natural variation, we analyzed the physiological and proteomic differences between Shandong (SD) ecotype and Xinjiang (XJ) ecotype.

Project description:Arabidopsis thaliana is not particularly stress tolerant and may lack protective mechanisms required to survive extreme environmental conditions. Thellungiella salsuginea has therefore attracted increasing interest as an alternative plant model species that possesses high tolerance of various abiotic stresses. While the T. salsuginea genome has recently been sequenced, its annotation is still far from complete and, due to the low number of ESTs available, evidence for actual transcriptional activity is lacking for most genes. ESTs were generated from a non-normalized and a normalized library synthesized from RNA pooled from plant samples from different developmental stages and grown under abiotic stress conditions. The ESTs of Thellungiella was sequenced by 454 pyrosequencing method. More than 1 million sequence reads were assembled into 42,810 unigenes, approximately 50% of which could be functionally annotated. From this sequence information, we constructed a 44k Agilent oligonucleotide microarray. A comparison of same-species and cross-species hybridization results showed the superior performance of the newly designed array for Thellungiella samples. In addition, the array was validated in a cold acclimation experiment that used the appropriately adapted MapMan software for analysis and visualization. To examine the quality of the Thellungiella array and to assess whether hybridization results from a dedicated array are superior to cross-species hybridization using the Arabidopsis array from the same manufacturer, we performed reciprocal array hybridizations. In this experiment, RNA from the Yukon accession of Thellungiella and RNA from the Col-0 accession of Arabidopsis were both hybridized on the Agilent Thellungiella and Arabidopsis expression arrays. For both species, RNA was extracted from acclimated and non-acclimated plants from three independent biological replicates.

Project description:Halophytes are plants that can naturally tolerate high concentrations of salt in the soil, and their tolerance to salt stress may occur through various evolutionary and molecular mechanisms. Eutrema salsugineum is a halophytic species in the Brassicaceae that can naturally tolerate multiple types of abiotic stresses that typically limit crop productivity, including extreme salinity and cold. It has been widely used as a laboratorial model for stress biology research in plants. Here, we present the reference genome sequence (241?Mb) of E. salsugineum at 8× coverage sequenced using the traditional Sanger sequencing-based approach with comparison to its close relative Arabidopsis thaliana. The E. salsugineum genome contains 26,531 protein-coding genes and 51.4% of its genome is composed of repetitive sequences that mostly reside in pericentromeric regions. Comparative analyses of the genome structures, protein-coding genes, microRNAs, stress-related pathways, and estimated translation efficiency of proteins between E. salsugineum and A. thaliana suggest that halophyte adaptation to environmental stresses may occur via a global network adjustment of multiple regulatory mechanisms. The E. salsugineum genome provides a resource to identify naturally occurring genetic alterations contributing to the adaptation of halophytic plants to salinity and that might be bioengineered in related crop species.

Project description:The overall objective was to document transcriptomic changes in the guard cells of Thellungiella salsuginea under short (1x) - and long-term (3x) saline growth conditions. For that. microarray analysis was performed using a 60-mer oligonucleotide probe array from Agilent (44 K, design number 031554, Santa Clara, CA, USA). It was clearly observed that salt salinity alters the transcriptomic landscape of Thellungiella guard cells. However, changes in gene expression were evident under 3x saline growth conditions compared to non-saline conditions. Similarly, more GO terms were significantly enriched in differentially expressed guard cell genes of 3x salt than 1x salt treated plants.
