View SamplesCuticular wax is a major composition of plant surface cuticle, which exerts crucial functions in optimizing plant growth. Histone acetylation regulates gene expression of diverse biological processes, but little is known about its role in cuticular wax synthesis. Here we observed that mutation of Arabidopsis histone acetyltransferase GCN5 gene impaired stem cuticular wax accumulation. Furthermore, three target genes of GCN5 (CER3, CER26 and CER1-L1) were identified by RNA-Seq and ChIP assays. Consistently, H3K9/14 acetylation levels in promoter regions of CER3, CER26 and CER1-L1 were significantly decreased in gcn5 as compared to wild type. Notably, overexpression of CER3 in the gcn5 mutant restored the stem cuticular wax accumulation. Collectively, these data demonstrate that Arabidopsis GCN5 is involved in stem cuticular wax accumulation by modulating CER3 expression via H3K9/14 acetylation, which present evidence that histone acetylation plays an important role in cuticular wax biosynthesis

View SamplesNitrogen availability in the soil is a major determinant of crop yield. While the application of fertilizer can substantially increase the yield on poor soils, it also causes nitrate pollution of water resources and high costs for farmers. Increasing the nitrogen use efficiency in crop plants is a necessary step to implement low input agricultural systems. We exploited the genetic diversity present in the world-wide Arabidopsis thaliana population to study adaptive growth patterns and changes in gene expression associated with chronic low nitrate stress, with the aim to identify biomarkers associated with good plant performance under low nitrate availability.

View SamplesIn order to identify differentially expressed genes in developing seeds of Arabidopsis thaliana three different stages of seed development were analysed (9-10, 10-11 and 12-13 days after flower opening) for two Arabidopsis thaliana accessions, Col-0 and C24. For each stage and accession three biological replicates were analysed.

View SamplesIn this study, we performed a NGS analysis to identify transcriptome landscape of the human placenta during uncomplicated single and twin pregnancy, to establish a pattern of normal placental genes expression for further comprehensive analyses. Additionall aim of these studies was to identify the differentially expressed transcripts of genes in single and twin pregnancy that may participate in human pregnancy.
