Bundle sheeth

bundle sheath cells A layer of cells in plant leaves and stems that forms a sheath surrounding the vascular bundles. In C 4 plants (see C4 pathway) the bundle sheath cells contain chloroplasts and are the site of the Calvin cycle. The initial fixation of carbon dioxide to form malic acid takes place in the palisade mesophyll cells,...

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. Bundle sheath extensions (BSEs) are linked to leaf gas exchange and drought tolerance but not to leaf mechanical and structural properties across species from a cool temperate forest. Abstract Bundle sheath extensions (BSEs) account for the physiological differences between heterobaric and homobaric species.

Abscisic acid (ABA) signaling has been postulated to be involved in this network. C3 plants are those plants where the first product of photosynthesis is a 3 carbon compound i.e. phosphoglyceric acid (PGA) while C4 plants are those plants where the first product of photosynthesis is a 4 carbon compound i.e oxaloacetic acid (OAA...

Bundle sheath (BS) cells form a single cell layer surrounding the vascular tissue in leaves. In C3 plants, photosynthesis occurs in both the BS and mesophyll cells, but the BS cells are the major sites of photosynthesis in C4 plants, whereas the mesophyll cells are only involved in CO 2 fixation. The function of bundle sheath is to facilitate various processes in the plants. Some of the roles include fixation of carbon during photosynthesis and transportation within the plant among others. The first sheath marked by the asterisk is a C315 His nondeflectable sheath used for His bundle mapping and lead placement. All other sheaths are used for either right atrial or right ventricular lead placement. C: Deflectable sheath used occasionally to place the His bundle lead (Medtronic, Inc.).
