Project description:Severe loss-of-function alleles of DCL1 are embryonic lethal. Defects in cell division were seen as early as the globular stage in the strong loss-of-function allele dcl1-15. Phenotypic work with dcl1-15 and the null allele dcl1-5 suggested that, in addition to the severe patterning defects, the mutants were maturing earlier than wild-type embryos. We performed global gene expression analysis of dcl1-15 and wild-type torpedo staged embryos to examine this maturation phenotype further. The results suggested that DCL1 is a heterochronic gene. Comparisons to a time series of embryo development (http://www.seedgenenetwork.net/arabidopsis) showed that the genes differentially expressed in dcl1-15 embryos behaved more like green-cotyledon stage embryos than torpedo embryos.

Seeds of a DCL1/dcl1-15 plant were sown. For each wild-type sample, 300 torpedo stage embryos were selected from wild-type siblings. For each mutant replicate, 300 dcl1-15/dcl1-15 embryos were selected from the siliques of DCL1/dcl1-15 where the wild-type embryos were at the torpedo stage.

Project description:DICER-LIKE1 (DCL1) is required for miRNA biogenesis and embryonic pattern formation. Presumably the patterning defects observed in dcl1-5 null embryos are due to the loss of miRNAs and the consequent up-regulation of their respective targets. To test which miRNA targets were up-regulated in dcl1 embryos relative to wild-type embryos, we performed genome-wide transcript profiling of wild-type and dcl1-5 early globular embryos using directional mRNA-Seq.

Project description:adt05-04_drn - mutant vs wildtype - DRN targets - Ovules containing heart-stage/torpedo-stage embryos were dissected from siliques and imidiately shock frozen in liquid nitrogen. RNA was extracted and sent to Evry for comparison between mutant and wildtype transcriptome. Keywords: gene knock out
