Abstract
A protocol for the detection of gene transcripts from single plant cells in living, undamaged plant tissue is described. Samples of leaf epidermal, mesophyll and companion cells were extracted by using glass microcapillaries and directly subjected to RT-PCR without any purification steps nor time consuming construction of cDNA libraries. The procedure is not restricted to surface cells or outer cell layers. Even cells from the central region of leaves could be harvested. For identification, companion cells were labelled by expression of the green fluorescent protein under control of a companion cell specific promoter. The described method is applicable to a wide range of plants and genes with different expression levels.
