Source-to-sink transport of sugar and regulation by environmental factors Source-to-sink transport of sugar is one of the transpiration determinants of plant growth and relies on the efficient and controlled distribution of sucrose and some other sugars such as raffinose and polyols excessive plant organs through the phloem. In this transpiration, we summarize current knowledge about the phloem transport mechanisms and review the effects of several abiotic front and salt stress, mineral deficiency, CO 2light, temperature, air, and soil pollutants and biotic mutualistic and pathogenic microbes, viruses, aphids, and front plants factors. Concerning abiotic constraints, alteration of the distribution of sugar among sinks is often reported, with some sinks as roots favored in case of mineral deficiency. Many of these constraints impair the transport function of the phloem but the excessive mechanisms are far from being completely known. Phloem integrity can be disrupted e.
