Abstract: Concomitant adjustments in photosynthetic capacity and size, composition, and/or density of minor foliar veins in response to growth environment were previously described primarily for winter annuals that load sugars into foliar phloem apoplastically. Here, common… read more here.

DOI: 10.1016/j.pbi.2018.01.009
Abstract: The complex form of higher plants requires continuous, balanced transport of nutrients in the phloem. The initial step of transferring sugars, amino acids, and other materials from photosynthetic cells to the conducting sieve tubes is… read more here.

Abstract: In Arabidopsis thaliana, phloem parenchyma transfer cells (PPTCs) occur in leaf minor veins and play a pivotal role in phloem loading. Wall ingrowth formation in PPTCs is induced by the phloem loading activity of these… read more here.

DOI: 10.1104/pp.16.01041
Abstract: A mathematical model of symplastic loading addresses the mechanisms and roles of active and passive phloem loading. In many species, Suc en route out of the leaf migrates from photosynthetically active mesophyll cells into the… read more here.

DOI: 10.3389/fpls.2022.787837
Abstract: Maintaining phloem transport under water stress is expected to be crucial to whole-plant drought tolerance, but the traits that benefit phloem function under drought are poorly understood. Nearly half of surveyed angiosperm species, including important… read more here.
