Upon digestion, the algae's light-harvesting factories--the chloroplasts--are sequestered in specialized cells in the slug's gut (there's even a name for this chloroplast theft: kleptoplasty).
Dr Brisson suspected that a protein family he has studied for years, called the "Whirlies" might be important to protect against mutations in plant cells - specifically in the chloroplast - the engine of photosynthesis that allows plants to transform carbon dioxide into sugar and expel the oxygen we breathe.
The objectives of this research are to study the molecular and physiological mechanisms underlying plants adaptation and survival to increasing UV-rich environment by investigating and comparing the oxidative stress responses of Arabidopsis thaliana plants and their callus tissues to increasing UVR and by investigating the photosynthetic activities of isolated chloroplasts from UVR-treated plants.
