Transcription profiling of Arabidopsis Bla-1/Hh-0 hybrids, Mir-0/Se-0 hybrids and their corresponding parents

ABSTRACT: Bla-1, Hh-0 and their F1 hybrid, and Mir-0, Se-0 and their F1 hybrid were grown for 3 weeks at 16 degreC long days. Whole rosettes were harvested and pooled 8-10 per sample.

Epistatic interactions between genes are a major factor in evolution. Hybrid necrosis is an example of a deleterious phenotype caused by epistatic interactions that is observed in many intra- and interspecific plant hybrids. A large number of hybrid necrosis cases share phenotypic similarities, suggesting a common underlying mechanism across a wide range of plant species. Here, we report that approximately 2% of intraspecific crosses in Arabidopsis thaliana yield F1 progeny that express necrosis ...[more]

Transcription profiling of Arabidopsis Umkirch-1/Umkirch-3 hybrid plants compared to siblings carrying a microRNA targeting the Umkirch-3 allele of At5g41750

Project description:Umkirch-1/Umkirch-3 hybrid plants (KB142-2) grown at 16 degreeC long day were compared with siblings carrying a microRNA targeting the Umkirch-3 allele of At5g41750. Plants were about 3 weeks old, and whole rosettes were harvested. Each sample is a pool of 8-10 individuals.

High-resolution analysis of parent-of-origin-allelic expression in Arabidopsis seeds

Project description:We report the identification of parent-of-origin specific gene expression in Arabidopsis seeds. F1 hybrid seeds were generated by reciprocally crossing Arabidopsis accessions Col-0 and Bur-0. Seeds were harvested at 4 DAP and total RNA was isolated and analyzed by deep sequencing.

Hybrid Mimics and Hybrid Vigor in Arabidopsis (F6 data)

Project description:F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor which form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants which have a F1 –like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines “Hybrid Mimics”, in which the characteristics of the F1 Hybrid are stabilized. These Hybrid Mimic lines, like the F1 Hybrid, have larger leaves than the parent plant, the leaves having increased photosynthetic cell numbers, and in some lines increased size of cells, suggesting an increased supply of photosynthate. A comparison of the differentially expressed genes in the F1 Hybrid with those of eight Hybrid Mimic lines has identified metabolic pathways altered in both; these pathways include down regulation of defense response pathways and altered abiotic response pathways. F6 Hybrid Mimic lines are mostly homozygous at each locus in the genome yet retain the large F1-like phenotype. Many alleles in the F6 plants, when they are homozygous, have expression levels different to the level in the parent. We consider this altered expression to be a consequence of trans-regulation of genes from one parent by genes from the other parent. Transregulation could also arise from epigenetic modifications in the F1. The pure breeding Hybrid Mimics have been valuable in probing the mechanisms of hybrid vigor and may also prove to be useful hybrid vigor equivalents in agriculture.

Genome-wide analysis of LINK1 and LINK2 effects on the Arabidopsis transcriptome

Project description:The goal of this study was to compare the transcriptional profile (RNA-seq) of wild type plants with that of link1link2 double mutants grown under continous light or long day (16h light/8 h darkness) conditions. In the first experiment wild-type and link1link2 mutant plants were grown for two weeks under continuous white light conditions at 22 degrees centigrades and the transcriptional profile of these plants was analyzed using RNA-seq. In the second experiment, wild-type and link1link2 mutants were grown under long day conditions (16 h light/8 h darkness), and the transcriptional profile of these plants was analyzed in samples harvested every 4 hours over a 24 hour time-course, starting 2 hours after the onset of the light period.
