View into plant cells: A membrane protein is targeted to two locations

Metabolic processes are especially complex in plants due to their obligate sessile life style. A metabolic pathway that has occupied plant researchers for decades is the oxidative pentose-phosphate pathway. Researchers at Münster University found that an important membrane protein is distributed to two cell organelles simultaneously, to provide reduction power at both locations. The researchers suppose that plants in which this pathway is blocked in peroxisomes may be less stress-resistant. The study was published in the journal “The Plant Cell”.
