- Description
- During growth and storage phases, plant cells import large amounts of carbon (C) and nitrogen (N) assimilates to drive their metabolism and to facilitate synthesis of storage products. Following assimilation, organic C and N metabolites are transported via the phloem (C) or via the xylem followed by phloem (N) to sink tissues. These translocation processes involve participation of metabolite transporters located in source and sink cells. While information on transporters mediating cellular efflux of C and N metabolites is scarce, cell import systems have been identified and characterized. An overview is provided on transporters importing amino acids, peptides, and sugars into plant cells with particular emphasis on their substrate selectivity, expression, and function.
