Unformatted text preview: n of the distribution of fixed carbon into various metabolic pathways. • Partitioning (between cells) – The differential distribution of photosynthates within the plant. Translocation Photosynthate Distribution • Allocation – The regulation of the distribution of fixed carbon into various metabolic pathways. • Storage • Metabolism • Transport Translocation Photosynthate Distribution • Allocation – Storage • Starch (primary storage form) is synthesized and stored in the chloroplasts Translocation Photosynthate Distribution • Allocation – Metabolism • Fixed carbon utilized to meet energy needs and provide carbon-based precursors Translocation Photosynthate Distribution • Allocation – Transport • Fixed carbon incorporated into transport sugars for export to sinks Translocation Photosynthate Distribution • Partitioning* – The differential distribution of photosynthates within the plant. it is important that plants partition because then it will end up alot of leaves and little roots. through partitioning the plants can balance between its root and leaves Translocation Photosynthate Distribution • Partitioning – The differential distribution of photosynthates within the plant • Principal sinks – – – – – – Meristems Young, developing leaves Non-photosynthetic stem tissues Flowers Young, developing fruits Seeds Translocation Photosyn...
