New Phytologist, 2023 SummaryThe evolution of the plant vascular system is a key process in Earth history because it enabled plants to conquer land and transform the terrestrial surface. Among the vascular tissues, the phloem is particularly intriguing because of its complex functionality.

The evolution of minor vein phloem and phloem loading [PDF]
American Journal of Botany, 2001 Phylogenetic analysis provides a rational basis for comparative studies of phloem structure and phloem loading. Although several types of minor vein companion cell have been identified, and progress has been made in correlating structural features of these cells with loading mechanisms, little is known about the phylogenetic relationships of the ...

Journal of Experimental Botany, 2014 The phloem is the long-distance solute-conducting tissue of plants. The observation of phloem cells is particularly challenging for several reasons and many recent advances in microscopy are, therefore, especially beneficial for the study of phloem anatomy and physiology.

Sclerification in the bark tissues of common fir (Abies alba Mill.)
Acta Societatis Botanicorum Poloniae, 2014 The sclerification process in bark tissues of common fir (Abies alba Mill.) has been described. The sclerification begins in 3 years old stems. Sclereids differentiate from cortical parenchyma cells and from secondary phloem parenchyma cells that do not ...

Spatial imaging of Zn and other elements in Huanglongbing-affected grapefruit by synchrotron-based micro X-ray fluorescence investigation [PDF]
, 2014 Huanglongbing (HLB) is a highly destructive, fast-spreading disease of citrus, causing substantial economic losses to the citrus industry worldwide. Nutrient levels and their cellular distribution patterns in stems and leaves of grapefruit were analysed ...

Measurement of sap flow dynamics through the tomato peduncle using a non-invasive sensor based on the heat field deformation method [PDF]
, 2013 Recent contradicting evidence on the contributions of xylem and phloem to tomato fruit growth highlights the need for a more thorough insight into the dynamics of sap flow through the tomato peduncle. In fact, knowledge on sap flow dynamics through small

The Small RNA Component of Arabidopsis thaliana Phloem Sap and Its Response to Iron Deficiency
Plants, 2023 In order to discover sRNA that might function during iron deficiency stress, RNA was prepared from phloem exudates of Arabidopsis thaliana, and used for RNA-seq. Bioanalyzer results indicate that abundant RNA from phloem is small in size—less than 200 nt.
