Biologie Résumé : Study results of response for seedlings of two bread wheat varieties ( Triticum aestivum L.) , Mahon-Demias (MD) and Hidhab (HD) to salt stress, indicate the highlight negative impact of salinity on the rate of germination and show the sensitivity of MD compared to HD.
Salt stress significantly reduced the length of roots and epicotyls of both varieties. MD showed a greater reduction in length of two characters than HD. Under salt stress of 200mM NaCl, the leaf area is reduced by 50.2 % for MD against 24.8 % for HD. Changes in water potential values and relative water content indicates that MD is more sensitive to salinity than HD. Monitoring the ionic content indicates that the accumulation of Na + is higher in the sheath of HD and the blade of MD, with little difference between varieties for the content of the roots. HD uses an additional mechanism to counter salinity, sequestering preferentially over sodium in the sheath unlike in the blade of MD variety. HD has a greater ability to accumulate K + ion in the limb and in the roots compared to MD. The K +/Na + ratio of leaf blade is higher in HD compared to MD. This indicates that it is mainly their leaves HD restores the balance of the osmotic potential via K+ and thus minimizes the effect of osmotic stress caused by NaCl. HD capacity to pump K + in the nutrient solution, and then to transfer to the limb, therefore a strategy for adaptation to salt stress via osmotic regulation. Results of study for the embryogenic capacity and power regeneration in vitro thermal and salt stress in MD and HD using mature embryos as explants show that MD responds better than HD in vitro selection. MD has a higher rate of induction of callus with a better callus induced
proliferation, but with fewer embryos induced by cal. The rate of regeneration of plantlets from proliferating callus was null for HD and very low for MD. The index sensitivity (IS)confirmed the tolerance of MD compared to HD for salt and thermal stress in vitro to a given parameter is the length of the roots. The results suggest the possibility of using the in vitro technique in selection for no biotic stress. Results of study for the expression analysis of five candidate genes for tolerance to salinity indicate that HKT1,5 and HKT2,2 are expressed in the roots, but not in sheaths and limbs, with better HKT1,5 gene expression in the roots of HD. This suggests a more active role HKT1, 5 genes in HD. The expression of anti-porter vacuolar Na +/H+, TNHX-1 roots, sheaths and limbs is higher in HD than in MD. Roots and sheath of the two genotypes accumulate more transcripts of the vacuolar pyrophosphatase
TVP1 than blades. Type similarity of gene expression TNHX1 and TVP1, observed in MD and HD, suggesting that vacuolar compartmentalization is equal efficiency in both genotypes.
More gene transcripts TaSOS-1, accumulate in the roots and sheath of MD compared to HD, suggesting that in addition to more effective retention of Na + in sheaths, HD avoids accumulation of Na + in the blade by activating its sodium efflux via high expression of SOS1 gene in this compartment. Results indicate that salinity tolerance in the bread wheat seems to be related to the ability to prevent the accumulation of toxic levels of Na +, associated with a high osmo-regulation and/or ability to maintain an acceptable level of K +, especially in the leaf blade. This information is useful for selection of plant material in cereal breeding programs.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/BEN6415.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9435 Selection In vitro pour la tolerance aux stress salin et thermique chez le ble tendre (Triticum aestivum l.)

Biologie Résumé : The main objective of this work is to overcome the effect of salt stress on wheat
through different techniques and biotechnology approaches, which are used to improve the behavior of different varieties of durum wheat and to select the best performing. Somatic embryogenesis is currently integrated into many selection schemes since it can significantly reduce the length of improvement cycles. Development of somatic embryos was obtained after cultivation of six varieties of durum wheat (Waha, GuemGoum Rkhem, Beliouni Adnan- 2, Beni and Adnan mestina-1) on a nutrient medium supplemented with 3.5mg / l 2.4-D. The selection of tolerant varieties to the salt stress was achieved by the addition of a selective agent: NaCl. This study is based on the addition of different concentrations of NaCl (0, 4, 8,
12, 16 g/l) to the medium to study the salt stress effect on the development of somatic embryogenesis. NaCl introduced to the regeneration medium was carried out by a sequential addition of different graded concentrations to determine the callus growth rate, the water content, the content of K +, Na + contents and the K + / Na + ratio in the presence orabsence of stress. Moreover, the application of salt stress through direct addition of different NaCl concentrations during the induction phase of callogenesis was exploited to determine the influence of stress on the rate of callogenesis, the germination rate, the rate of embryogenic calli, the regeneration rate and the average number of regenerated plants per callus. in vitro regeneration has proved susceptibelty to the development of somaclonal variation, because
when callogenesis, somatic cells must be adapted to the culture medium and generate new changes in the genome. The detection of these variations is generally performed through revelation techniques by molecular methods. In this study, DNA extracted from the regenerated plants was subjected to polymerase chain reaction (PCR) that allowed, from this template DNA in the presence of arbitrary 9 RAPD primers to obtain a degree of polymorphism indicating the presence of somaclonal variation. Analysis of RAPD profiles revealed that the presence of somaclonal variation may be the result of many crop cycles, application of a severe stress weans and different responses of durum wheat genotypes for cultivation in vitro regeneration.

Biologie Résumé : In Algeria grain legumes are considered as an important nourishing food, they are very rich in proteins. Molybdenum has an important role in several biological processes in plants, that is why our research focuses on three legumes species (bean, chickpea and lens) submitted to salt stress and in presence of molybdenum and nitrogen.
Combination of molybdenum and nitrogen in salt stress (3g/l of NaCl) condition, leads to an increase in fresh shoot biomass and chlorophyll (a+b).
Molybdenum and nitrogen stimulate synthesis of total proteins in bean but in roots of chickpea and lens, salt stress causes their increase.
In bean and chickpea shoots, xanthine dehydrogenase activity is stimulated by both molybdenum and nitrogen.
Aldehyde oxidase activity is stimulated in bean shoots by adding molybdenum and nitrogen, and in lens roots in salt stress condition.
Sulfite oxidase has a decreasing activity which decreases with time and is affected by salt stress. Nitrate reductase activity increases in time and is affected by salt stress.
The activity of the molybdenum cofactor decreases because of salt stress except for lens which increases. For bean, sulphite oxidase and xanthine dehydrogenase genes have a role in adaptation to salt stress condition.
The expression of mARC chickpea gene and mARC2 bean gene is stimulated in condition of salt stress which gives them a role to salt stress adaptation.

For this purpose a factorial experiment was performed on the soil in pots in a completely randomized block design with four concentrations of NaCl (S0: 0, S1 25, S2 50 S3: 150) mmol / L and four concentrations of potassium as KH2PO4 (K0:0, K1:10, K2:20, K3:40) mmol / L with four replications under controlled conditions, the work was done on 64 experimental units. Morphological observation during the germination phase showed that salinity has a depressive effect on the germination percentage (GP) germination capacity (GC), germination rate (GR) and the germination stress index (GSI) .During the seedling development phase salt stress resulted in an increase in stomatal resistance (RS) which reflected on stomatal conductance (SC) these physiological traits are linked to the accumulation of solutes (glucose, proline ) which may be due to the
