Mitochondria from the Mesophyll Cells of Zea mays Leaves

Journal of Plant Physiology, 1984
Improvements in preparative techniques have made it possible to isolate and purify mitochondria from the mesophyll cells of Zea mays leaves. Contamination by mitochondria from the bundle sheath cellswas insignificant. The use of a self-generatedPercoll gradient allowed the purification of washed mitochondria from the mesophyll cells and considerably ...

Fine structure of mesophyll cells in senescing leaves of Phaseolus

Planta, 1966
1. In fully senescent mesophyll cells from Phaseolus almost all the cytoplasmic contents had been lost apart from the resistant plasmalemma and some small empty vesicles. In some parts of the cell groups of plastids, together with occasional distorted mitochondria, spherosomes and a few ribosomes also remained.

Effects of freezing on plant mesophyll cells.

Symposia of the Society for Experimental Biology, 1990
Freezing and thawing of leaves of herbaceous plants leads to damage when the freezing temperature falls below a certain tolerance limit, which depends on the plant species and state of acclimation. Such damage is expressed as an irreversible inhibition of photosynthesis observed after thawing.

EFFECTS OF PARAQUAT ON THE ULTRASTRUCTURE OF MESQUITE MESOPHYLL CELLS*

Weed Research, 1969
Summary. The effect of paraquat (l,1′‐dimethyl‐4,4′‐bipyridylium‐24) on the ultra‐structure of mesophyll cells of honey mesquite (Prosopis juliftora (Swartz) DC. var. glandulosa (Torr.) Cockerell) was studied by means of electron microscopic techniques.

Vacuoles of Mesophyll Cells as a Transient Reservoir for Assimilates

Russian Journal of Plant Physiology, 2001
We studied the efflux of radioactive photosynthetic products from the central vacuole into the cytosol of protoplasts isolated from the mesophyll tissue of the sugar beet (Beta vulgaris L.) after their darkening and subsequent cessation of photosynthesis.

Occurrence of Lomasomes in Mesophyll Cells of ‘Khapli’ Wheat

Nature, 1964
Moore and McAlear coined the name ‘lomasome’ (λωμα—border; σωμα—body) to describe the sponge-like structures which they observed between the cell walls and plasmalemmas in the hyphae of several species of fungi under the electron microscope. They considered that lomasomes were characteristic of, and peculiar to, the fungi and suggested that they might ...

Preservation of the Differentiated State of Mesophyll Cells In Vitro

Annals of Botany, 1988
Under a variety of light conditions, and in a modified NT medium containing sucrose as a carbon source, isolated mesophyll cells of Calystegia sepium started cell divisions after 72 h. Alternately, under light-dark alterations (12: 12 h; 1.35–1.50 W m−2 of cool white light), and culture in the NT medium lacking an organic carbon source, and made iso ...

Redifferentiation of Single Mesophyll Cells into Tracheary Elements

International Journal of Plant Sciences, 1994
Plant cells possess a potency to redifferentiate to other types of cells in response to external stimuli. The differentiation of mesophyll cells into tracheary elements (TEs) is an excellent example of redifferentiation occurring at the cellular level in vascular plants.

Ultrastructural observations on the mesophyll cells of pine leaves

Canadian Journal of Botany, 1971
The ultrastructure of mesophyll cells of Pinus strobus has been investigated in the spring and winter months. Wall invaginations begin in the early spring and eventually give the cells a lobed appearance. The chloroplasts are of the normal stroma lamella – grana type and completely ring the cells by winter.

An Unusual Layer of Cells in the Mesophyll of the Soybean Leaf

Botanical Gazette, 1967
In soybean leaves a distinctive layer of mesophyll cells, one cell layer in thickness, extends horizontally between the veinlets, in the plane of the phloem. Anatomical features of the layer suggest that it is concerned with the translocation of photosynthate from the palisade parenchyma to the veins.
