“…The main mechanisms of wild plants for resisting severe environmental conditions (e.g. salinity, drought and high temperatures) at the Arabian Gulf region have recently been discussed [1,10]. There are three main mechanisms which enable plants to cope with those factors:…”

“…The first type is found in some native plants like A. lagopoides [15], and Atriplex spp., and possibly other native plants including monocot plants, while the second type of salt glands is found in Tamarix, Limonium, and Frankenia. Several authors have described and discussed the structure and function of these salt glands [1,7]. Some of these halophytes have salt glands capable of excreting a substantial amount of Na + outside the plant body as compared to K + , with the best-known Cl --ATPase pump to channel Cloutside the plant body.…”

“…In native plants, drought avoidance mechanisms can be seen through conservation of water in their leaves; Tetraena qatarense is a good example [1], or by acceleration of water absorption, as observed in Helianthemum lipii ( Figure 6). More details can be found in some recent articles [1,10] with good examples from the flora of Qatar. (b) Tolerance mechanism: Plants tolerate severe environmental conditions mainly by the accumulation of organic and inorganic solutes.…”

“…(b) Tolerance mechanism: Plants tolerate severe environmental conditions mainly by the accumulation of organic and inorganic solutes. Compatible osmolytes such as proline, gylycinebetaine, soluble sugars such as trehalose and some organic acids are accumulated in plant tissues to cope with the harsh environments of salinity, drought and high temperatures [1,12]. Ascorbic acid (vitamin C) as an organic acid, accumulates under extreme saline conditions, and it is worth discussing its role here; as an enzyme cofactor might play many functions especially those related to photosynthesis and growth [19].…”

“…As such, the soil is vulnerable to more desertification and salinization, receives very little rainfall as the annual rainfall may be below 80 mm, ECe may reach above 200 dSm -1 for various reasons, and temperatures may exceed 50°C during summer. Thus, the climate of this region is considered as warm and humid throughout the year and the land is arid or semi-arid with highly saline soils [1]. The physiography of the State of Qatar is based on a number of studies which started in the mid-seventies of the last century [2,3] and recognized at least seven regions and soil types: (1) Rocky desert, (2) Rawdahs, (3) Sabkhas, (4) Sand formations, (5) Intertidal areas, (6) Islands, and (7) Cultivated lands.…”

Several studies have investigated the biology of native plants (halophytes and xerophytes), biological soil crusts (BSC), as well as the associated and adjacent microorganisms. These studies concentrated on their eco-physiological aspects as well as the possible roles they might play in various life activities and industries. This article presents the mechanisms adopted by these living organisms to cope with the harsh environment, and the possible roles microorganisms might play to support native plants, some important examples from the flora of Qatar are presented to show these mechanisms. Special attention has been paid to the senescence and death of leaves or whole plants, since this strategy has been considered as an important option for escaping extreme environmental conditions. Discussion about solute accumulation (organic and inorganic) in all native living organisms in general and in microorganisms in particular, could result to further investigation to clarify their roles in such an ecosystem. Some case studies have been reported to discuss the ecological aspects at two main types of habitats in Qatar; Rawdahs and Sabkhas were chosen to show how native living organisms adapt in these habitats. This study discussed the general identification of BSC and microorganisms, as well as their possible roles in the soil biota. The possible methods and mechanisms exhibited by extremophiles to support native plants in coping with saline and arid lands have also been reported in this article. This study also discussed the recent outlook about the origin of metabolic activities in these living organisms to support the growth of native plants under stress conditions.

Scarcity of water and the small area of the agricultural land are considered as the crucial environmental issues challenged the Arabian Gulf countries. In this study, experiments were conducted to identify the salt tolerance during the germination and the seedling stages of some native halophytes in the State of Qatar. Seeds of eight native species (Salsola setifera, Halopeplis perfoliata, Caroxylon imbricatum, Suaeda aegyptiaca, Acacia tortilis, Limonium axillare, Tetraena qatarensis and Aeluropus lagopoides) were investigated. Except for Tetraena qatarensis, Acacia tortilis and Suaeda aegyptiaca, all achieved ≥ 30% of seed germination at a concentration of 200 mM NaCl. Around 30% of Salsola setifera seeds were able to germinate in a salt concentration of 400 mM. Germination recovery of seeds that have been treated with 800 mM NaCl for 3 weeks was the greatest for Halopeplis perfoliata (94%) and the lowest for Aeluropus lagopoides (22%). Five halophytes were investigated for seedling growth under saline irrigation ranged from 0 to 600 mM NaCl. No significant differences obtained in growth biomass of seedlings of each of Caroxylon imbricatum, Suaeda aegyptiaca and Tetraena qatarensis between saline and non-saline treatments.
