Index. décimale : 570 Sciences de la vie. Biologie Résumé : Knowledge of the physiological, biochemical, agronomic and technological traits involved in plant adaptation process to abiotic stresses is a decisive step in the fight against drought. This study is a contribution to understanding the mechanisms of tolerance to water stress in bread wheat varieties Triticum aestivum L. and to establish genotype-environment interactions to evaluate the genotypic variability.
In the first series of tests, the study shows that the varieties introduced Cham 6 Hamam 1 and Attila are the most productive. The local variety Ain Abid followed by Attila of Angi-4 are the most tolerant to water stress.
The second experimental trial is to test during two campaigns, 10 bread wheat lines at three different geo-climatic sites: Setif, Constantine and Guelma. The results of phenological, morphological and agronomic parameters fluctuate over time and space. The earliest species provide lower performance parameters to Guelma, while the later varieties give the best yields in Constantine. Local varieties Ain Abid, Arz and introduced line Prl / 2 * Pastor provide the best yield and its components on Setif sites. This last line with Pastor / Wbll1 and Hidhab feature a performance by high yield and components of yield on Constantine and Guelma.
The interaction genotype-environment is very highly significant between all studied agronomic parameters.
On the site of Setif (semi-arid) are rated the highest levels of total protein for Thelin line // 2 * Attila * 2 / Pastor, while Prl / 2 * Pastor accumulates the most important starch contents on Constantine site. Total protein levels are higher on experimental testing of Setif, while higher levels of starch and moisture are obtained for all varieties grown on Constantine and Guelma. The genotype-environment interaction is highly significant for all biochemical and technological parameters. The data show that the line Kauz / Pastor / Fiscal has the highest values W (dough strength) to G (swelling of dough), it also gives the best Pelshenke compared to other lines, it is followed by Pastor / Wbll1 and Thelin // 2 * Attila * 2 / Pastor lines. The latter are characterized by a very high baking strength (strength of wheat). It's on the sites of Setif and Guelma that are expressed wheat lines with the most efficient technological parameters.
The wide variability in gluten strength, character controlled mainly by the allelic variation of loci Glu-A1; Glu-B1; Glu-D1, gives an idea about the genetic diversity obtained by expression and composition of these loci. Gluten, rheological parameters alveograph (W, P), Pelshenke test and SDS sedimentation volume vary as a function of the allelic diversity HMW glutenins. The results show the superiority of the alleles 22, (6 + 8), (7 + 9), (2 + 12), (10 + 5) and (7 + 8), compared to other alleles controlling these parameters.

Crop losses arising are important. In favorable years the Yellow rust, for example, can take extents epidemic and destroy entire harvests. (A.Ouffroukh., 2008; A.Ouffroukh., 2006; B. Bahri, M. Leconte, A. Ouffroukh, C. Vallavieille-Pope, J. Enjalbert, 2009). Viral diseases in turn, are taking extension. Thus, the Barley Yellow Dwarf Virus (BYDV.) or (BYDV) was reported in several areas prospected and several cereal species (wheat and barley hard and soft).
In general very little information is available on their epidemiology and economic impact, when the means of struggle, they have little or almost nonexistent (H. Stone and JP Signoret, 1978). BYDV (BYDV) little known in Algeria compared to other diseases, can be very important for our cereal and threatening, particularly since this disease is transmitted by insect vectors belonging to the genus including Aphidideae, including a dozen some species have been identified (A.Ouffroukh., 2006; L.

Also after his observation and detection, identity veered ¬ was confirmed by serological investigations have shown that the existence of two viral strains or Pathotypes (PAV and MAV), confirming the results obtained by H. Belkahla.et Lapierre (1999).
The frequency of the disease varies annually from 8% to 18% depending on the region but is also encountered and generally on the different species at rates ranging from 8% to 28%. (L. Ayadi K. and Ayoub, 1994; A. Ouffroukh., 2008; Ouffroukh. A Khelifi. D, Dehimet. L, 2009).
In terms of capacity vector, PR appears to be best vector and infected plants by this species appear most affected clinically, about the impact of contamination on cereal species studied, it appears that the barley species are most affected, while soft wheats are more susceptible to BYDV (BYDV) and durum wheats.

Biologie Résumé : The in vitro evaluation of three durum wheat genotypes (Djenah Khetifa, Oued Zenati
and Waha( to water stress tolerance simulated in vitro by different concentrations of
PEG 6000 indicated significant differences among genotypes, PEG concentrations and
their interactions for all the studied characters, indicating genetic variability in PEGsimulated drought stress. The osmotic pressure has negatively affected all parameters
studied. However, cells that continue to grow under severe osmotic stress are
considered as tolerant to water stress. In vitro screening for stress tolerance reveals the
variety Djenah Khetifa as the most tolerant and Waha as sensitive. The studied traits can
be recommended as suitable selection criteria for screening drought-tolerant genotypes.
Three amplified and reproducible locus (gwm331, gwm335 and gwm427) were retained.
These loci provided in total 78 monomorphic loci of which 69 were detected in somaclones.
Five somaclonal variants (DKR1-S1, DKR1-S2, OZR1-S2, WR1-C3 and WR1-S1) were
identified by only two SSR markers. Genetic variation rate was 21.74%. The presence of
selective agent in the medium could explain the observed genetic variations. Somaclonal
variation cannot always be detected at the gross morphological level. The selected SSR
markers could be used to study the uniformity of plants obtained from tissue culture and
varietal identification. Analysis of the proteins by a new two-dimensional diagonal
electrophoresis approach named (D-2DE) followed by MALDI-TOF mass spectrometry
has identified six differentially expressed proteins. For each variety, the level of mRNA
expression of three candidate genes (globulin, GAPDH and peroxidase) and a
ubiquitous (Actine) gene was determined by qRT-PCR. The amounts of mRNA of the
three genes are partially correlated with the amounts of proteins. These genes were
slightly up-regulated over the control. The D-2DE results were validated using Western
blot analysis with specific anti-globulin and anti-glyceraldehyde in the embryogenic
calli of wheat, in response to water stress. The proteins identified through this technique
provide new insights as to how calli respond to osmotic stress. Our method of study
provides an original and relevant approach that could contribute significantly to a better
understanding of possible linkages between the abundance of specific proteins and the
acclimation of durum wheat to water stress at the cellular level.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/KAC7070.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10531 Sélection in vitro pour la tolérance au stress hydrique chez le blé dur (Triticum durum Desf) : approche protéomique, transcriptomique et génétique.

The level of total lipids and triglycerides were significantly reduced, however the level of total cholesterol, HDL cholesterol and LDL cholesterol was increased in all groups.
The results of urine tests (kaliuresis, natriuresis, proteinuria) showed a significant signs of dehydration with a significant increase in total protein in dehydrated rats.
Thyroid failure reflected by a decrease in the level of plasma FT4 and FT3 was noted after dehydration, malnutrition and their association. A significant decrease in plasma TSH was observed in malnourished rats and dehydrated and malnourished rats; this level was decreased but not significantly in dehydrated rats.
