Gene Expression in Arabidopsis thaliana Guard Cells


ABSTRACT: Stomata are formed by a pair of specialized guard cells that control the opening and closing of the stomatal pores on the leaf surface. These pores are the main route for microbe penetration into leaves. However, plants show a remarkable ability to close the pore when sensing the presence of microbial invaders; a phenomenon recently described as stomatal immunity. This study was initiated to understand the transcriptional regulation of this early plant defense against pathogens.

Stomata, micro-pores on the leaf surface, are formed by a pair of guard cells. In addition to controlling water loss and gas exchange between the plant and the environment, these cells act as immunity gates to prevent pathogen invasion of the plant apoplast. Here, we report a brief procedure to obtain highly pure guard cell preparations using conditions that preserve the guard cell transcriptome as much as possible for a robust high-throughput RNA sequence analysis. The advantages of this proced  ...[more]
