Protocol: fine-tuning of a Chromatin Immunoprecipitation (ChIP) protocol in tomato.

ABSTRACT:

Background

Searching thoroughly for plant cis-elements corresponding to transcription factors is worthwhile to reveal novel gene activation cascades. At the same time, a great deal of research is currently focused on epigenetic events in plants. A widely used method serving both purposes is chromatin immunoprecipitation, which was developed for Arabidopsis and other plants but is not yet operational for tomato (Solanum lycopersicum), a model plant species for a group of economically important crops.

Results

We developed a chromatin immunoprecipitation protocol suitable for tomato by adjusting the parameters to optimise in vivo crosslinking, purification of nuclei, chromatin extraction, DNA shearing and precipitate analysis using real-time PCR. Results were obtained with two
