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

Project description: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.

Co-immunoprecipitation of FAMA-interacting proteins in Arabidopsis thaliana seedlings

Project description:Identifying interaction partners and protein complex compositions for transcription factors (TFs) can produce valuable information on the mechanisms by which they regulate gene expression or are themselves regulated by signaling pathways in the cell. FAMA is a TF that is specifically expressed in the last stages of stomatal guard cell development in the epidermis of young leaves and other aerial tissues of higher plants. It is a master regulator of guard cell development and promotes terminal differentiation of the guard cell precursor by both activating and repressing hundreds of genes. How this is achieved mechanistically is still unclear. We therefore isolated putative FAMA interaction partners from young Arabidopsis seedlings expressing FAMA-CFP under the FAMA promoter using proteasome inhibitor treatment and formaldehyde crosslinking, followed by a classical co-immunoprecipitation mass spectrometry approach. Plants expressing nuclear GFP under a stomatal lineage specific promoter were used as controls. In two independent experiments with different crosslinking and immunoprecipitation conditions, we found ICE1, a known heterodimerization partner of FAMA, to be enriched in FAMA-CFP versus control samples. Other proteins with known transcriptional regulator or co-regulator function were not identified, presumably due to the low abundance of the bait protein. The interaction of FAMA with BRXL2, another regulator of guard cell development, which was detected in one experiment, is likely an artifact since BRXL2 does not localize to the nucleus under normal conditions.

Microarray analysis of scap1 mutant and wild type in Arabidopsis thaliana guard cell protoplast

Project description:Stomata are highly specialized organs which consist of pairs of guard cells and regulate gas and water vapor exchange in plants. While early stages of guard cell differentiation have been described and were interpreted in analogy to processes of cell type differentiation in animals, the downstream development of functional stomatal guard cells remains poorly understood. We have isolated an Arabidopsis mutant, scap1 (stomatal carpenter 1), that develops irregularly shaped guard cells and lacks the ability to control stomatal aperture, including CO2-induced stomatal closing and light-induced stomatal opening. SCAP1 was identified as a plant-specific Dof-type transcription factor expressed in maturing guard cells but not in guard mother cells. SCAP1 regulates the expression of genes encoding key elements of stomatal functioning and morphogenesis, such as a K+ channel protein, MYB60 transcription factor, and pectin methyl esterase. Consequently, ion homeostasis was disturbed in scap1 guard cells, and esterification of extracellular pectins was impaired so that the cell walls lining the pores did not mature normally. We conclude that SCAP1 regulates essential processes of stomatal guard cell maturation and functions as a key transcription factor regulating the final stages of guard cell differentiation.

Sucrose modulation of the Arabidopsis thaliana guard-cell transcriptome

Project description:Microarrays were used to evaluate the effect of sucrose on gene expression in guard cells. Strips of Arabidopsis leaves were incubated with sucrose or mannitol or no sugars, then the leaves were freeze dried and guard cells were dissected from the leaf strips and analyzed.

Agilent data from Arabidopsis thaliana enriched guard cell tissue and leafs.

Project description:To identify genes of the guard cell transcriptome of Arabidopsis thaliana enriched guard cell samples were compared with total leaf tissue. Genes of the abscisic acid and humidity response of Arabidopsis thaliana guard cells were identified by treatment with ABA-Spray and low humidity.
