Project description:In angiosperms, the mature seed consists of an embryo (E), a seed coat (SC), and, in many cases, an endosperm. In contrast to knowledge about embryo and endosperm, we have relatively little knowledge of SC, especially at the genomics level. In this study, we analyzed the gene expression during seed development using the panel of cultivated and wild pea genotypes. We report the comprehensive gene expression changes related both to development as well as domestication status. Analysis of seed developmental stages revealed extensive modification of gene expression between wild pea progenitor and cultivated pea crop. A significant difference in gene expression dynamics appeared between early and late developmental stages D1, D2, and D3, D4, D5 in wild pea genotypes, where the expression was increased 3-5-fold and 5-10-fold, respectively. Our work extends knowledge about the role of the seed coat during pea seed development. We described gene expression dynamic resulting in specific metabolic profiles providing new insight into pea domestication.

Project description:Modification of cis regulatory elements to produce differences in gene expression level, localization, and timing is an important mechanism by which organisms evolve divergent adaptations. To examine gene regulatory change during the domestication of maize from its wild progenitor, teosinte, we assessed allele-specific expression in a collection of maize and teosinte inbreds and their F1 hybrids using three tissues from different developmental stages. Our use of F1 hybrids represents the first study in a domesticated crop and wild progenitor that dissects cis and trans regulatory effects to examine characteristics of genes under various cis and trans regulatory regimes. We find evidence for consistent cis regulatory divergence that differentiates maize from teosinte in approximately 4% of genes. These genes are significantly correlated with genes under selection during domestication and crop improvement, suggesting an important role for cis regulatory elements in maize evolution.

Project description:Through domestication, humans have substantially altered the morphology of Zea mays ssp. parviglumis (teosinte) into the currently recognizable maize. A wealth of archeological and population genetic data has established maize as a model system for studying domestication , genome evolution and the genetics and evolution of complex traits. We used expression profiling of 18,242 genes for 38 diverse maize genotypes and 18 teosinte genotypes to examine how domestication has re-shaped the transcriptome of maize seedlings. We detected evidence for more than 600 genes having significantly different expression levels in maize compared to teosinte as well as 800 genes with significantly altered co-expression profiles reflective of substantial rewiring of the transcriptome since domestication. These genes likely include loci with altered expression due to domestication. The genes with altered expression show a significant enrichment for genes located in regions that previous population genetic analyses have identified as having undergone a selective sweep during maize domestication; thirty-two genes previously identified as putative targets of selection also exhibit altered expression levels and co-expression relationships. We also identified 45 genes with altered, primarily higher, expression in inbred relative to out-crossed teosinte. These genes are over-represented for genes that function in response to biotic stress and may reflect responses to the effects of inbreeding. This study not only documents alterations in the maize transcriptome following domestication and identifies several genes that may have contributed to the evolution of maize but also highlights the complementary information that can be gained by combining gene expression with population genetic analyses.

We assayed genome-wide cis and trans regulatory differences between maize and its wild progenitor, teosinte, using deep RNA sequencing in F1 hybrid and parent inbred lines for three tissue types (ear, leaf and stem) followed by assessment of allele-specific gene expression.
