WebbThe phloem lectin PP2 and phloem protein PP1 are found in the phloem of many plants. In situ hybridization shows that the mRNAs encoding these proteins are localized only in companion cells, and immunocyto-chemistry shows localization of the proteins in both companion cells and sieve elements ( Bostwick et al. , 1992; Clark et al. , 1997, …
WebbThere are two major types of transport vessels within the plants vascular system: xylem and phloem (pronounced zy-lem and flo-em). Xylem tubes carry water and minerals obtained from the roots of the plant to the tissues above ground. Phloem tissue transport the sugars produced in the leaves to the tissues in the rest of the plant. WebbPhloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored. Primary phloem originates from the procambial regions in meristems, while secondary phloem originates from the vascular cambium. Phloem contains specialized cell types.
