Project description:Drought is a major environmental stress that limits growth and development of cool-season annual grasses. Drought transcriptional profiles of resistant and susceptible lines were studied to understand the molecular mechanisms of drought tolerance in annual ryegrass (Lolium multiflorum L.). A total of 4,718 genes exhibited significant differential expression in two L. multiflorum lines. Additionally, up-regulated genes associated with drought response in the resistant lines were compared with susceptible lines. Gene ontology enrichment and pathway analyses revealed that genes partially encoding drought-responsive proteins as key regulators were significantly involved in carbon metabolism, lipid metabolism, and signal transduction. Comparable gene expression was used to identify the genes that contribute to the high drought tolerance in resistant lines of L. multiflorum.

Project description:Heavy metal cadmium (Cd) affects seriously crop growth, quality and yield, and has potential threats to human safety. We found the difference of two ryegrasses (Lolium multiflorum Lam.), a high-Cd tolerance (LmHC) and a low-Cd tolerance (LmLC) cultivars , in response to cadmium stress. The germination rate, plant growth, and fresh weight of LmHC were much better than that of LmLC. So we use RNA sequencing to investigate the differentially expressed genes(DEGs) about cadmium response between LmHC and LmLC. Real-time quantitative PCR analysis showed that the same DEGs of LmLC and LmHC had obviously difference expression level under Cd treatment. It was suggestion that differential expression of DEGs might be involved in regulating Cd tolerance, accumulation and translocation.These results will be helpful for understanding the underlying molecular mechanism in Cd toxicity and provide references for improving the ecological environment through genetic improvement.

Project description:In the present study, genomic binding sites of glucocorticoid receptors (GR) were identified in vivo in the rat hippocampus applying chromatin immunoprecipitation followed by next-generation sequencing. We identified 2470 significant GR-binding sites (GBS) and were able to confirm GR binding to a random selection of these GBS covering a wide range of P values. Analysis of the genomic distribution of the significant GBS revealed a high prevalence of intragenic GBS. Gene ontology clusters involved in neuronal plasticity and other essential neuronal processes were overrepresented among the genes harboring a GBS or located in the vicinity of a GBS. Male adrenalectomized rats were challenged with increasing doses of the GR agonist corticosterone (CORT) ranging from 3 to 3000 μg/kg, resulting in clear differences in the GR-binding profile to individual GBS. Two groups of GBS could be distinguished: a low-CORT group that displayed GR binding across the full range of CORT concentrations, and a second high-CORT group that displayed significant GR binding only after administering the highest concentration of CORT. All validated GBS, in both the low-CORT and high-CORT groups, displayed mineralocorticoid receptor binding, which remained relatively constant from 30 μg/kg CORT upward. Motif analysis revealed that almost all GBS contained a glucocorticoid response element resembling the consensus motif in literature. In addition, motifs corresponding with new potential GR-interacting proteins were identified, such as zinc finger and BTB domain containing 3 (Zbtb3) and CUP (CG11181 gene product from transcript CG11181-RB), which may be involved in GR-dependent transactivation and transrepression, respectively. In conclusion, our results highlight the existence of 2 populations of GBS in the rat hippocampal genome. - See more at: http://press.endocrine.org/doi/10.1210/en.2012-2187?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%3dpubmed#sthash.LqK088DP.dpuf
