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

ABSTRACT: 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. total samples analysed are 24: 4 biological independent replicates of: total leaf (COL-0) vs. enriched guard cells (COL-0); ABA-sprayed enriched guard cells (gl1-1) vs. control-sprayed enriched guard cells (gl1-1); low humidity (20%rh) treated enriched guard cells (COL-0) vs. high humidity (80%) treated enriched guard cells (COL-0)

Stomata are pores on the leaf surface, bounded by two guard cells, which control the uptake of CO(2) for photosynthesis and the concomitant loss of water vapor. In 1898, Francis Darwin showed that stomata close in response to reduced atmospheric relative humidity (rh); however, our understanding of the signaling pathway responsible for coupling changes in rh to alterations in stomatal aperture is fragmentary. The results presented here highlight the primacy of abscisic acid (ABA) in the stomatal  ...[more]
