The D3cpv Cameleon reports Ca²âº dynamics in plant mitochondria with similar kinetics of the YC3.6 Cameleon, but with a lower sensitivity.

Mitochondria are key organelles involved in many aspects of plant physiology and, their ability to generate specific Ca²âº signatures in response to abiotic and biotic stimuli has been reported as one of their roles. The recent identification of the mammalian mitochondrial Ca²âº uniporter opens a new research area in plant biology. To study the mitochondrial Ca²âº handling, it is essential to have a reliable probe. Here we have reported the generation of an Arabidopsis transgenic line expressing the genetically encoded probe Cameleon D3cpv targeted to mitochondria, and compared its properties with the already known Cameleon YC3.6.
