Abstract

Studying the implication of hydrogen peroxide in biological processes in plants remains a challenge due to the current shortcomings of H₂O₂-responsive probes. The use of ContPY1, a new fluorescent probe, which is highly selective and sensitive for H₂O₂, was investigated. To validate the use of ContPY1 on plants, we have generated protocols employing cells suspensions and leaves, and measured specifically H₂O₂ production by plants using spectrofluorometry and microscopy.
