Project description:FLP and MYB88 are two paralogous MYB proteins, regulating the symmetric division of guard mother cell during Arabidopsis stomatal development. To understand their molecular functions, we performed genome-wide identification of FLP/MYB88 binding targets using ChIP-chip with FLP/MYB88 antibody. By comparing ChIP-chip between wild-type and flp-1 myb88 lines, a total genes were identified as putative direct targets for FLP/MYB88.

Ten-day old wild-type and flp-1 myb88 Arabidopsis green tissues were used for ChIP. Rabbit polyclonal antibody recognizing FLP and MYB88 proteins was used for chromatin immunoprecipitation

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.
