Bundle sheeth

bundle sheath definition: nounA layer or region of specialized cells surrounding a vascular bundle....

Bundle sheath cells are altered later and to a lesser extent than the mesophyll cells. Les cellules de la gaine périvasculaire sont altérées plus tardivement et moins profondément que celles du mésophylle. The bundle sheath chloroplasts of C. longifolia contain extensive grana stacking and are distributed throughout the cell.

In angiosperm: Leaves …layer of parenchyma called the bundle sheath. Only the midvein and some large lateral veins have any secondary growth.

Bundle sheath extensions show strong birefringency, whereas mesophyll cells appear as dark‐green regions. The arrows indicate the different passages of the microprobe (see also Figs 3 & 5). Bar = 120 μm. D. Hand‐cut transverse section of a mature leaf of V. vinifera, under polarized light. Bundle sheath extensions show birefringency, whereas mesophyll cells appear as dark‐green regions. The bundle sheath provides a conduit linking veins and mesophyll cells. In the C 3 plant Arabidopsis thaliana, it also plays important roles in oxidative stress and sulphur metabolism. However, the mechanisms responsible for the patterns of gene expression that underpin these metabolic specializations are poorly understood.
