Project description:To understand how GA functions in regulating embryo development, a genome-wide transcriptomic analysis was carried out using 9DAF seeds dissected from siliques of dellaq (rga28 gai rgl1 rgl2) and the wild-type (col-0-2) grown in full-spectrum white fluorescent light at 22°C under long day conditions (16 h light/8 h dark). Then we found that GA regulates embryo development via DELLA-LEC1interaction, a subsequent genome-wide transcriptomic analysis was carried out using 9DAF seeds dissected from siliques of lec1-4 and the wild-type (col-0-1) in the same growth condition. Basing on the criteria of 1.5-fold cutoff for the genes with 5% false discovery rate, we first identified the differentially expressed genes in dellaq vs col-0-2, lec1-4 vs Col-0-1 subsets, which are referred to as DELLA and LEC1 regulated genes. These data reveal that DELLAs and LEC1 co-target a set of common genes in late embryogenesis, strongly supporting the role of DELLA-LEC1 in embryo development.

Project description:The aim of this study was to analyze the impact of autotetraploidy on gene expression in Arabidopsis thaliana by comparing diploid versus tetraploid transcriptomes. In particular, this included the comparison of the transcriptome of different tetraploid A. thaliana ecotypes (Col-0 vs. Ler-0). The study was extended to address further aspects. One was the comparison of the transcriptomes in subsequent generations. This intended to obtain information on the genome wide stability of autotetraploid gene expression. Another line of work compared the transcriptomes of different diploid vs. tetraploid tissues. This aimed to investigate whether particular gene groups are specifically affected during the development of A. thaliana autotetraploids. Samples 1-8: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 9-12: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 13-24: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 leaves (6th - 8th). The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 25-32: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 leaves (6th - 8th). The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 33-36: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid vs. tetraploid Ler-0 seedlings from the second (F2) and third (F3) generation after induction, respectively. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 37-40: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid vs. tetraploid Col-0 seedlings from the second (F2) and third (F3) generation after induction, respectively. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 41-44: Arabidopsis thaliana Col-0/Ler-0 diploid transcriptome. Transcriptional profiling and comparison of diploid Col-0 vs. diploid Ler-0 seedlings. The experiment was carried out with pedigree of esrablished lines. Samples 45-48: Arabidopsis thaliana Col-0/Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid Col-0 vs tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 and Ler-0 lines.

Project description:The loss-of-function mutation of the RGE1 (retarded growth of embryo) gene, which is expressed during seed development, caused small and shriveled seeds. The embryo of the loss-of-function mutant showed retarded growth after the heart stage although abnormal morphogenesis and pattern formation of the embryo and endosperm was not observed. RGE1 expression was determined in endosperm cells using the β-glucuronidase reporter gene and RT-PCR. The differences of expression profile between rge1-1 and wild type Col-0 was examined to know the functions of RGE1. The result of Microarray analysis showed specific down-regulation of putative GDSL motif lipase genes in the rge1-1 mutant indicating possible involvement of these genes in seed morphology.
