Authorities have estimated that around one billion hectares of land (or between eight and ten percent Clf the earth's land surface) can be classified as salt affected (F.A.O., ; Malcolm, ), with about 12 million hectares occurring in Western Austra1ia (Selected Committee on Salinity, ).

Krouglicof has written: 'Structural relationships between mesophyl and bundle sheath cells in atriplex' Asked in Biology, Botany or Plant Biology, Genetics What specialized. bundle-sheath-like cells, the distinctive cells, form longitudinal strands that are not associated with vascular tissue.
While distinctive cells (DCs) appear to function like bundle sheath cells (BSCs), they differ developmentally in two ways: they are derived from ground meristem rather than procambium and they are formed plastochrons later.

Atriplex halimus L. (Amaranthaceae) (Mediterranean saltbush) is a halophytic shrub that is widely distributed in arid and semi-arid regions around the Mediterranean basin and east to Saudi Arabia, at elevations less than m. It grows on a variety of soils, from fine to coarse texture, with varying degrees of salinity.
There are two sub-species of A. halimus: halimus is diploid (2n = 2x = 18 Cited by: Anatomical changes in the roots and leaves of Atriplex semibaccata R. Br., induced by salinity stress, as well as photosynthetic and stomatal response to salinity, were investigated.
As salinity increased, decreases were observed in root diameter and leaf size, as well as in the number of chloroplasts in the chlorenchyma and bundle sheath by: Information on Atriplex and Commonly Grown Garden Species. There are between and species in the Atriplex genus; the number varies due to disputes in classification by botanists.
The genus is part of the Chenopodioideae family, which itself is under scrutiny by botanists; it is a sub-family of the Amaranth family Amaranthaceae.
Many members of the Atriplex genus are very tolerant to. Forty-day-old seedlings of Atriplex halimus were treated either with NaCl (50, and mM) for the subsequent 30 days or with 15% PEG for the subsequent 10 days.
As much as 50 mM of NaCl significantly increased shoot fresh and dry weight and height; nevertheless, or mM NaCl seemed to have no effect.

We crossed the C 3 species Atriplex prostrata with the C 4 species Atriplex rosea to produce F 1 and F 2 hybrids. All hybrids exhibited C 3-like δ 13 C values, and had reduced rates of net CO 2 assimilation compared with A. activities of the major C 4 cycle enzymes PEP carboxylase, NAD-malic enzyme, and pyruvate-P i dikinase in the hybrids were at most 36% of the C 4 Cited by: Latin atriplex, from Ancient Greek ἀτράφαξυς (atráphaxus), which is a substrate loan.

leucoclada. The growth reduction could not be explained by water deficit because both Atriplex species were able to reduce their shoot water potential as a consequence of a decreased osmotic potential (mainly by Na+ and Cl-- accumulation) in all plant organs.

Endomitosis, the formation of cells containing multiples of the normal somatic number, is a phenomenon encountered in Atriplex root-tips, and one that complicates chromosome counting.
Diploid, tetraploid and octoploid cells are commonly present in the same root-tip preparation. Polyploid cells increase in number along the root-tip. Net photosynthesis and dark respiration studies were conducted on Atriplex confertifolia (Torr.

Oviposition takes place on the tips of shoots. The larva at first mines strip-like full depth corridors in the apical leaves, going then into the stem, which it hollows out, so that it becomes translucent.
Creeping saltbush (Atriplex semibaccata) Long recognized as a valuable colonizer and soil stabilizer in disturbed environments, the potential for creeping saltbush as a desirable cover crop species in low rainfall vineyard environments has only recently been explored.

The fruits are enclosed in disc-shaped bracteoles — a bract that protects the early floral bud — after. the genus Atriplex are known for their high tolerance to ari-dity and salinity (Le Houerou ). Using halophytes to produce forage in saline lands is the best economic solution (Khan and Duke ).
Halophytes can play a role in soil reclamation in degraded lands (Le Houerou ). Atriplex are the dominant plants in arid and semi-arid lands. Ten plants of Pdf vesicaria were grown in liters of pdf culture solution to which no sodium had been intentionally added.
