Photosynthesis: Study reveals how minerals are involved in homeostasis of chloroplasts

A study led by LMU biologist Professor Hans-Henning Kunz has revealed the role of minerals in the homeostasis of chloroplasts, which are essential for photosynthesis. Plants fix 258 billion tons of CO2 annually in their chloroplasts, requiring specific minerals, particularly iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn). Disruptions in ion homeostasis can impair photosynthesis, affecting growth and yields. The research team, which includes members from Munich, Bochum, Columbia (MO), and Saarbrucken, has deciphered the chloroplast ionome of various plant species.
