Gene expression in the epidermis including guard cells of phot1 phot2 and pGC1::SOC1-GFP/phot1 phot2

ABSTRACT: Stomata pores are surrounded by a pair of guard cells in the epidermis in plants. Stomata apature is controlled by environmental factors. Stomata opening is also enhanced by introduction of SOC1-GFP driven by GC1 promoter in phot1 phot2 double mutants (pGC1::SOC1-GFP/ phot1 phot2). Epidermis including guard cells were isolated from phot1 phot2 and pGC1::SOC1-GFP/phot1 phot2 and gene expression were analyzed. phot1-5 phot2-1 in gl1 background (phot1 phot2) and pGC1::SOC1-GFP/phot1 phot2 were grown under 16 h light / 8h dark, constant 22?C conditions for 4 to 5 weeks. Epidermis including guard cells were isolated from leaves of these plants. Three biological replicates were used.

Stomatal movements are regulated by multiple environmental signals. Recent investigations indicate that photoperiodic flowering components, such as CRY, GI, CO, FT and TSF, are expressed in guard cells and positively affect stomatal opening in Arabidopsis thaliana. Here we show that SOC1, which encodes a MADS box transcription factor and integrates multiple flowering signals, also exerts a positive effect on stomatal opening. FLC encodes a potent repressor of FT and SOC1, and FRI acts as an acti ...[more]

Project description:We addressed the integrated analysis of mRNA and miRNA expression levels of Tg6799 AD model mice at 4 month and 8 months of age. Total 8 gene cluster modules for co-expression network were predicted from transcriptome data and 6 modules were show relation with AD or aging. We constructed early stage AD network using data integration between mRNA and miRNA profiles and predicted miRNAs strongly involved in module regulation. We found that ARRDC3 showed AD mutation dependent changes of expression and was related metabolic dysfunction in early stage AD. These results demonstrate that candidate genes on the simultaneous profiling of mRNA and miRNA expressions in genome wide can be used for the understanding of non-coding RNA related gene expression in early stage AD. We suggested that our results could be future candidate to be developed as early biomarkers in progressive AD pathology. This result can be used for the further application in neurodegenerative diseases. Tg6799 transgenic mice were purchased from The Jackson Laboratory (USA) and were housed under a 12h light-dark cycle with free access to food and water. Female Tg6799 mice are maintained until 4 months and 8 months of age (for littermate control: LM and mutant subjects: MT). RNA samples were isolated from hippocampus of mice using TRI-Reagent (Sigma-Aldrich, St. Louis, MO) according to the manufacturer’s instructions. Gene expression was analyzed with GeneChip® Mouse Genome 430 2.0 Arrays (Affymetrix, Santa Clara, CA), which is comprised of over 45,000 probe sets representing approximately 28,700 well-characterized mouse genes. The Ion Total RNA-Seq Kit v2 (Lifetechnologies, USA) was used for the preparation of micro RNA libraries according to the manufacturer's instructions. Total numbers of subject used are as followed: 1) LM 4 months : MT 4 months : LM 8 months : MT 8 months (2:4:2:4) for screening mRMA and miRNA, 2) LM 4 months : MT 4 months : LM 8 months : MT 8 months (4:4:4:4) for expression verification.
