The secret phloem of pumpkins [PDF]
Proceedings of the National Academy of Sciences, 2010 The phloem of higher plants transports the products of photosynthesis and other nutrients over long distances from leaves to sink tissues, such as fruits, tubers, and roots, where they are used in growth or storage. The primary conducting cells of the phloem are the enucleate sieve elements, which are intimately connected to their neighboring companion

Diversity of the Superfamily of Phloem Lectins (Phloem Protein 2) in Angiosperms [PDF]
Plant Physiology, 2003 Abstract Phloem protein 2 (PP2) is one of the most abundant and enigmatic proteins in the phloem sap. Although thought to be associated with structural P-protein, PP2 is translocated in the assimilate stream where its lectin activity or RNA-binding properties can exert effects over long distances.

An Aphid-Secreted Salivary Protease Activates Plant Defense in Phloem.
Current Biology, 2020 Recent studies have reported that aphids facilitate their colonization of host plants by secreting salivary proteins into host tissues during their initial probing and feeding.

The Plant Journal, 2020 Taxus stem barks can be used for paclitaxel extraction. However, the composition of taxoids across the whole stem and stem tissue-specificity of paclitaxel biosynthesis-related enzymes remain largely unknown.

Sphingolipid biosynthesis modulates plasmodesmal ultrastructure and phloem unloading [PDF]
Nature Plants, 2019 During phloem unloading, multiple cell-to-cell transport events move organic substances to the root meristem. Although the primary unloading event from the sieve elements to the phloem pole pericycle has been characterized to some extent, little is known

Phloem Mobility of Magnesium [PDF]
Plant Physiology, 1970 Magnesium-28 was applied to specific leaves of bean (Phaseolus vulgaris) and barley (Hordeum vulgare) plants. After 24 hours, as much as 7% of the absorbed Mg was exported from the treated bean leaves and 11% was transported basipetally from the treated zone of the barley leaves.

Local and Systemic Effects of Brassinosteroid Perception in Developing Phloem.
Current Biology, 2020 The plant vasculature is an essential adaptation to terrestrial growth. Its phloem component permits efficient transfer of photosynthates between source and sink organs but also transports signals that systemically coordinate physiology and development ...

Current Biology, 2020 Plant cells can change their identity based on positional information, a mechanism that confers developmental plasticity to plants. This ability, common to distinct multicellular organisms, is particularly relevant for plant phloem cells.

Phloem Loading in Squash [PDF]
Plant Physiology, 1977 Squash (Cucurbita pepo L. var. melopepo torticalis, Bailey) leaves were supplied with (14)C-sucrose, then specific radioactivities of the glucose and galactose moieties of translocated stachyose were determined. In every case, the specific radioactivity of the galactose moiety was greater than that of the glucose moiety.
