Identification of LEC1 binding sites in Arabidopsis bent cotyledon stage seeds

Project description:LEAFY COTYLEDON1 (LEC1), an atypical subunit of the NF-Y CCAAT binding transcription factor, is a central regulator that controls many aspects of seed development including the maturation phase during which seeds accumulate storage macromolecules and embryos acquire the ability to withstand desiccation. To define the gene network and developmental processes controlled by LEC1, genes regulated directly by and downstream of LEC1 were identified. In this part of the study, we identified the genes bound by LEC1 in Arabidopsis bent cotyledon stage seeds. We expressed a GFP-tagged form of LEC1 under the control of its native promoter and terminator in lec1 null mutant seeds. Using an anti-GFP antibody (NeuroMab 75-131) , we performed chromatin immunoprecipitation followed by sequencing (ChIP-Seq) using chromatin isolated from bent cotyledon stage seeds to identify the genes bound by LEC1.

Identification of LEC1 binding sites in soybean embryos at 3 developmental stages

Project description:LEAFY COTYLEDON1 (LEC1), an atypical subunit of the NF-Y CCAAT binding transcription factor, is a central regulator that controls many aspects of seed development including the maturation phase during which seeds accumulate storage macromolecules and embryos acquire the ability to withstand desiccation. To define the gene network and developmental processes controlled by LEC1, genes regulated directly by and downstream of LEC1 were identified. In order to identify the genes bound by LEC1 in soybean embryos, we used two antibodies specific for soybean LEC1 (GmLEC1) and performed chromatin immunoprecipitation followed by sequencing (ChIP-Seq) using chromatin isolated from soybean embryos at the cotyledon, early maturation and mid-maturation stages.

Identification of LEC1 binding sites in Arabidopsis seeds during embryo expansion stage

Project description:LEAFY COTYLEDON1 (LEC1), a subunit of the NF-Y CCAAT binding transcription factor, is a key regulator that controls many aspects of seed development including embryo growth and seed storage accumulation. To identified genomic region bound by LEC1 and target genes of LEC1, we expressed a FLAG-tagged form of LEC1 under the control of its native promoter and terminator in lec1-4 mutant seeds. Using an anti-FLAG antibody (Sigma), we performed chromatin immunoprecipitation followed by sequencing (ChIP-Seq) using chromatin isolated from mature stage seeds to identify the genes bound by LEC1. These data reveal that the transcription regulation network of LEC1.

Expression data from tissues during somatic embryogenesis in Arabidopsis

Project description:We collected tissues from bent cotyledon stage zygotic embryos, proliferating tissue at day 7 and day 14 induction of somatic embryogenesis and mature somatic emrbyos in a wild type (Col-0) and vtc2 (SALK_146824) insertion. We used microarrays to identify global patterns of gene activity during somatic embryogenesis in a wild type (Col-0) and vitamin C deficient mutant (vtc2) RNA was extracted and amplified from four stages of somatic embryogenesis (bent cotyledon, day 7 induction, day 14 induction, and mature somatic embryos) in a wild type (Col-0) and vitamin C deficient mutant (vtc2) before being hybridized to the Arabidopsis ATH1 GeneChip in duplicate (two biological replicates).

Temperature-induced transcriptome profiles of endosprem and embryo during seed development and germination in Brassica oleracea

Project description:To understand how endosperm and embryo perceive temperature signals to control seed vigour in Brassica oleracea, we grow plants in 16°C till bent-cotyledon stage, which is a key stage sensing temperature. Then plants were either transferred to 26°C or kept in 16°C. Endosperm/seed coat and embryo RNA samples were collected for RNA-seq at day0, day1, day3, day7, day18 and day22. Further, RNA-seq was also performed in imbibed seeds matured in 16°C and 26°C, at 1 hour, 24 hours and 72 hour after imbibition.

mRNA changes following induction of LEC1 activity in Arabidopsis seedlings

Project description:LEAFY COTYLEDON1 (LEC1), an atypical subunit of the NF-Y CCAAT binding transcription factor, is a central regulator that controls many aspects of seed development including the maturation phase during which seeds accumulate storage macromolecules and embryos acquire the ability to withstand desiccation. To define the gene network and developmental processes controlled by LEC1, genes regulated directly by and downstream of LEC1 were identified. In this part of the study, we identified the genes regulated by LEC1 by overexpressing an inducible form of LEC1 in Arabidopsis seedlings and identifying the mRNAs induced EARLY (1h) after induction of LEC1 activity.

Identification of LEC1 target genes

Project description:The transcription factor (TF) LEAFY COTYLEDON1 (LEC1) acts as an essential regulator of Arabidopsis embryogenesis and seed development. It controls aspects of early embryogenesis such as cotyledon identity and suspensor morphology, as well as seed maturation processes such as storage compound accumulation, acquisition of desiccation tolerance and dormancy. To identify downstream components of the LEC1 regulon, dexamethasone-regulated expression of LEC1 and ChIP/chip were applied and revealed the enrichment of phytohormone- as well as elongation-related genes among LEC1 target genes.
