Webb1 jan. 2001 · CmPP16 from Cucurbita maxima was cloned and the protein was shown to possess properties similar to those of viral movement proteins. CmPP16 messenger RNA (mRNA) is present in phloem tissue, whereas protein appears confined to sieve elements (SE). Microinjection and grafting studies revealed that CmP … WebbThe phloem vascular system provides a path for assimilate transport from source to sink. The phloem conduits distribute the sugars made in the leaves to growing tissues and organs that cannot carry out photosynthesis. These ‘sinks’ include shoot and root apices, flower buds, and developing fruit and seed. Xylem conduits are responsible for ...

Webb11 jan. 2024 · What transports phloem? Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and Turgeon 2009), a process that raises the solute concentration. Webb10 okt. 2024 · The act of photosynthesis transforms plants into food. The phloem is the tissue that transports the plant’s blood from one part to another. Food moves upward and downwards, depending on its position in phloem, in bi-directional transport. Plants transport nutrients and water throughout their foliage in order to transport them.
