WebbFör 1 dag sedan · Tissue specificity analysis showed that Pbr037356.1 was highly abundant in root and phloem tissue but much less so in the xylem, the shoot apex, and leaves, as determined by RT-qPCR (Fig. 1 E). These results indicated that Pbr037356.1 mRNA level are high in the vasculature, making it a potential phloem-mobile mRNA. Webb4.1.4.1 Vascular Tissues. Vascular tissue is comprised of the xylem and the phloem, the main transport systems of plants. They typically occur together in vascular bundles in all plant organs, traversing roots, stems, and leaves. Xylem is responsible for the transport of water and dissolved ions from the roots upwards through the plant.
