Function of chloroplast located sugars in acclimation to cold temperatures
The functional details of stromal sugar accumulation during cold acclimation are only poorly understood. We gained further evidence that chloroplast located sugars are involved in cold acclimation, identified a novel chloroplast located sugar transporter with impact on frost tolerance and showed that that stromal sugar homeostasis affects chloroplast/nucleus signal exchange. A differential envelope proteome identified novel acclimation modulators. Our proposed work helps to understand how these modulators effect acclimation functionally, will broad our understanding of chloroplasts-nucleus signaling during acclimation and reveals how chloroplasts regulate protein abundance of the envelope with critical impact on acclimation.
