Water deficit is the major factor limiting durum wheat (Triticum durum Desf.) production and productivity. In this context, a first experiment was conducted to study the effect of seed priming by glycine betaine (GB) on the germination of durum wheat under water deficit stress induced by polyethylene glycol (PEG 6000). Five treatments were applied...

Drought is one of the major abiotic stresses affecting agricultural production. This stress has negative effects on the quality, production and productivity of durum wheat (Triticum durum Desf.), especially in arid and semi-arid areas. This work focused on i) the effect of seed priming by salicylic acid (SA) on durum wheat germination under drought...

Unlabelled: Cadmium, a carcinogenic and toxic substance released into the environment, has emerged as a potent activator of lysine-63 ubiquitination, and lysine-63 is a crucial regulator of signal transduction pathways. Although critical, very little information is currently available about how the activation of lysine 63 ubiquitination by Cd migh...

their genetic diversity. This study assessed the genetic diversity among thirty-nine date palm cultivars fromTunisia (Phoenix dactylifera) and India (Phoenix sylvestris) by using six AFLP (Amplified Fragment Length Poly-morphism) markers. 360 loci were amplified, with 127 loci polymorphic (34.35 %). The Jaccard’s similaritycoefficient ranged from 0...

Fusarium foot and root rot is one of the most important soilborne diseases of cereals, specifically on durum wheat which is the main cultivated species in the Mediterranean regions. This work aimed to evaluate the response of durum wheat and bread wheat to this disease under different climatic conditions. The disease parameters, grain yield loss as...

Lysine-63-linked ubiquitination -, i.e., The conjugation of a chain of ubiquitins linked through lysine63 has emerged as a key mechanism regulating signal transduction pathways. Although critical, very little information is currently available about how subversion of lysine 63 ubiquitination might contribute to cancers and inflammatory diseases. Th...

Heading date, plant height, and spike-related phenotypes are key traits that affect the yield potential and adaptation of barley to Mediterranean environments. These traits are controlled by a complex network of genes as well as environmental effects. Marker-trait associations (MTAs) were performed using a set of 361 barley genotypes, evaluated phe...

Genotype by environment interaction and stability analyses are among the most important evaluations conducted in plant breeding. In this study, we evaluated the yield-related traits of 32 Tunisian barley ( Hordeum vulgare L.) accessions over three consecutive cropping seasons in a semi-arid environment. Phenotypic analysis identified heading date a...

The heading date and growth habit are key factors that regulate the transition from the vegetative to the reproductive stage in barley. In this study, we used PCR based markers to identify the allelic variations in the Vrn-H1 (HvMB5) and Vrn-H2 (HvSNF2) genes and to predict the heading date and growth habit of a collection of Tunisian barley assess...

In barley breeding programs, information about genetic dissimilarity and population structure is very important for genetic diversity conservation and new cultivar development. Tis study aimed to evaluate the genetic variation in Tunisian barley accessions (Hordeum vulgare L.) based on simple sequence repeat (SSR). A total of 89 alleles were detect...

Identifying QTLs (quantitative trait loci) that control yield related traits under a stressed environment is very useful for marker-assisted selection (MAS). Marker-trait associations (MTA) for several agro-morphological traits were performed with 130 Tunisian and exotic spring bread wheat (Triticum aestivum L.) accessions under a semi-arid climate...

In crop breeding program, information about genetic dissimilarity on breeding resources is very important to corroborate genealogical relationships and to predict the most heterozygotic hybrid combinations and inbred breeding. This study aimed to evaluate the genetic variation in Kenyan sunflower breeding lines based on simple sequence repeat (SSR)...

Twenty-four barley accessions were grown in 2016 and 2017 successive seasons in order to estimate the variability of some desired traits and to study the amount of variation for different parameters. Genetic parameters, correlations, regressions and variance were estimated for all the traits. The highest positive correlation was obtained between gr...

QTL cloning of genes controlling rice agronomic traits has elucidated the contributions of such genes to phenotypes. However, we face difficulties in the isolation of genes with relatively small effects on phenotypes. Next-generation sequencing technology allows us to explore the allelic differences among diverse populations by rapid full-genome se...

Seed dormancy--the temporary failure of a viable seed to germinate under favorable conditions--is a complex characteristic influenced by many genes and environmental factors. To detect the genetic factors associated with seed dormancy in rice, we conducted a QTL analysis using chromosome segment substitution lines (CSSLs) derived from a cross betwe...

Preharvest sprouting resistance is an important agronomic trait of rice, since preharvest sprouting reduces grain quality. The level of seed dormancy is an important component of varietal variation in the resistance. To isolate a gene involved in seed dormancy and to understand the genetic control of dormancy, we attempted to delimit the candidate...
