Summary: The study aimed to evaluate the effects of two biannual rotations and four residue rate incorporation on durum wheat production and its nutritional composition and nutrient extraction. Results showed that the highest grain and residue production of durum wheat was obtained after the bean crop, along with the highest extraction of most nutrients.

Summary: The study analyzed the diversity of root systems in six durum wheat accessions under drought conditions and evaluated root traits using a high-throughput phenotyping scanner. The results showed significant variability in root development, distribution, and architecture among the different genotypes. Interestingly, the two drought-tolerant genotypes exhibited different root system ideotypes and rooting patterns. Furthermore, a positive correlation was found between the root angle of plants grown in greenhouse conditions and plants grown in the field.

Summary: Research suggests that diversifying cropping systems using cereal-legume mixtures is crucial for ensuring food security for the growing global population and mitigating environmental impacts and climate change. Simple variables can be used to estimate grain yield of wheat-legume intercrops under low nitrogen input conditions. Further mechanistic understanding of cultivar responses to interspecific competition is needed for optimal intercropping design and management.

Summary: This study evaluated the yield stability of 67 lines of durum wheat derived from interspecific crosses under various environmental conditions, and found that some lines showed high productivity and stability in different environments, making them suitable for unpredictable climatic conditions. Limited backcrosses can produce high yielding and stable germplasm while increasing diversity in a breeding pipeline. Comparing different stability approaches, it was found that some methods can be used interchangeably while others can be complementary to achieve both broad adaptation and higher yield.

Summary: This study characterized 151 durum wheat cultivars and advanced lines from Kazakhstan-Siberia Spring Wheat Improvement Network through phenotypic and molecular analysis. The longer growing season in Almaty resulted in a higher number of grains per spike. Despite smaller grain size, there was no correlation in germplasm performance between the two sites.

Summary: This study estimates the historical global area of durum wheat cultivation based on data from major producing countries. During the 19th century, durum wheat accounted for around 14-16% of global wheat production, but its proportion declined steadily as new wheat varieties were introduced. Currently, its proportion remains stable at around 6-7%.

Summary: The study reveals distinct gene and metabolite expression patterns in response to nitrogen starvation in two different tetraploid wheat genotypes, with durum wheat showing broader and stronger responses compared to emmer wheat. Durum wheat exhibits tighter regulation of metabolism compared to emmer wheat. Glutamate and GABA play critical roles in the genotype-specific response to nitrogen starvation in durum wheat and emmer wheat.

Summary: The study demonstrated that soil applications of Se and Si were effective in reducing Cd accumulation in wheat, leading to decreased toxicity to humans. Selenium was more effective than Si in mitigating Cd-induced toxicity, especially in soft wheat, likely due to the higher tolerance of durum wheat to Cd. The regulation of Cd transport genes by Se and Si applications played a key role in reducing Cd concentrations in wheat grains.

Summary: The mechanism and course of Triticum plastome evolution are still unknown, and this study aimed to investigate the evolution of Triticum plastomes during recent polyploidization. The complete plastomes of two polyploid wheat species, Triticum sphaerococcum and Triticum turgidum subsp. durum, were analyzed and compared to other Triticum plastomes. The results showed a conserved gene content in different Triticum species and a positive correlation between the number of repeats and plastome size. Additionally, a Triticum phylogeny was constructed, providing insights into the divergence time of various Triticum species.

Summary: Addressing climate change challenges in durum wheat production is crucial for ensuring food and nutrition security in the Mediterranean region. Exploiting the genetic variability in landrace populations has emerged as a strategy to enhance durum wheat adaptation to environmental stresses. This review highlights the importance of durum wheat landraces as a genetic resource for improving the sustainability of Mediterranean agroecosystems, focusing on adaptive traits and the development of molecular markers for selection.

Summary: This study traced the origin of Spanish durum wheat and olive tree landrace collections through genetic structure analysis and historical records. Spanish durum wheat landraces did not cluster geographically and likely came from intense grain circulation within the country and abroad from the 15th to 19th centuries. Spanish olive tree landraces experienced lower genetic circulation over time and can be divided into two groups: those from the south, of Maghrebi origin, and those from the east, likely originating from Italy in Roman times. The plant material of these two crops showed different levels of genetic circulation.

Summary: This research aims to optimize the removal of phenolic compounds from Olive Mill Wastewater (OMW) using sawdust and red clay as natural adsorbents. The study found that the adsorbent dose has the most significant influence on polyphenol removal for both adsorbents. The temperature and choice of red clay also affect the removal efficiency. Additionally, OMW was found to have a phytotoxic effect on seed germination.

Summary: This study investigated five modern varieties of durum wheat harvested in northern Tunisia, analyzing their technological and nutritional characteristics. The results showed that all wheat samples had low grain glassiness values, fatty acidity, and moisture levels, while having high thousandths weight, weight, and monounsaturated fatty acids. They also contained appreciable amounts of gluten and total protein. Dihydroferulic acid was identified as the most abundant phenolic compound. The wheat variety strongly influenced technological and chemical parameters, as shown by chemometric tools.

Summary: In this study, 19 GASA genes were identified and analyzed in Triticum turgidum. Their chromosomal locations, exon-intron distribution, physiochemical properties, and subcellular localization were determined. Differential expression patterns of these genes in various tissues and under different stress conditions were observed, indicating their potential roles in growth, development, and stress responses. The heterologous expression of certain GASA genes in yeast showed improved stress tolerance, suggesting their involvement in abiotic stress mechanisms.
