Project description:LEAFY COTYLEDON2 activity was induced via a LEC2-Glucocorticoid Receptor fusion protein in Arabidopsis seedlings. Experiment Overall Design: Transgenic plants carrying a 35S:LEC2-Glucocorticoid Receptor transgene were used for LEC2 induction. Activity was induced in 8 day old seedlings for 1 or 4 hours with Dexamethasone application. Controls include uninduced transgenic plants and non-transgenic plants treated with Dex. Experiment Overall Design: Two biological replicates per treatment.
Project description:Post-transcriptional gene regulation plays a significant role in the response to oxygen deprivation. Here, we utilized advances in next-generation sequencing technology to examine changes in transcriptional control, mRNA loading on to polysome, and regulation of ribosome activity during mRNA translation in 7-day-old Arabidopsis seedlings subjected to 2 hour hypoxia treatment.
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.
Project description:Transcriptional profiling of Arabidopsis wild-type (Col0) control seedlings with corresponding mutant seedlings is performed using Aligent's Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K).
Project description:Some soil bacteria promote plant growth, including Pseudomonas species. With this approach we detected significant changes in Arabidopsis genes related to primary metabolism that were induced by the bacteria. Pseudomonas G62 was applied to roots of 18 day-old Arabidopsis seedlings and the transcriptional profile of whole seedlings after 6 hours of treatment was analyzed.
Project description:Transcriptional profiling of Arabidopsis wild-type (Col0) control flower buds or seedlings with corresponding mutant flower buds or seedlings is performed using Aligent's Whole Arabidopsis Gene Expression Microarray (G2519F, V4, 4x44K).
