“…Triticum aestivum L. (bread wheat) is an essential grain worldwide, including Egypt. It provides humanity their protein requirements [ 1 , 2 ]. In developing countries, the requirement for wheat grains increased every year and is predicted to reach 60% by 2050 [ 3 ].…”

Wheat is a major nutritional cereal crop that has economic and strategic value worldwide. The sustainability of this extraordinary crop is facing critical challenges globally, particularly leaf rust disease, which causes endless problems for wheat farmers and countries and negatively affects humanity’s food security. Developing effective marker-assisted selection programs for leaf rust resistance in wheat mainly depends on the availability of deep mining of resistance genes within the germplasm collections. This is the first study that evaluated the leaf rust resistance of 50 Egyptian wheat varieties at the adult plant stage for two successive seasons and identified the absence/presence of 28 leaf rust resistance (Lr) genes within the studied wheat collection. The field evaluation results indicated that most of these varieties demonstrated high to moderate leaf rust resistance levels except Gemmeiza 1, Gemmeiza 9, Giza162, Giza 163, Giza 164, Giza 165, Sids 1, Sids 2, Sids 3, Sakha 62, Sakha 69, Sohag 3 and Bany Swif 4, which showed fast rusting behavior. On the other hand, out of these 28 Lr genes tested against the wheat collection, 21 Lr genes were successfully identified. Out of 15 Lr genes reported conferring the adult plant resistant or slow rusting behavior in wheat, only five genes (Lr13, Lr22a, Lr34, Lr37, and Lr67) were detected within the Egyptian collection. Remarkedly, the genes Lr13, Lr19, Lr20, Lr22a, Lr28, Lr29, Lr32, Lr34, Lr36, Lr47, and Lr60, were found to be the most predominant Lr genes across the 50 Egyptian wheat varieties. The molecular phylogeny results also inferred the same classification of field evaluation, through grouping genotypes characterized by high to moderate leaf rust resistance in one cluster while being highly susceptible in a separate cluster, with few exceptions.

“…spelta L.) are considered as an important source of nourishment for humans and livestock. Therefore, wheat cultivation is extensively performed and is of substantial economic importance [ 11 , 12 ]. Furthermore, spelt wheat grain is identified as a great source of fiber, vitamins (A, E, D), and microelements (selenium, zinc, copper), and thus, its consumption is known to have a positive impact on human health [ 13 ].…”

Changes in root-associated fungal communities in Triticum aestivum ssp. spelta L. and Triticum aestivum ssp. vulgare L. under drought stress and in various soil processing

Plant roots are inhabited by an enormous variety of microorganisms, including fungi, which can control the growth as well as regulate the health of the host plants. The mycobiome composition of the roots of wheat plants, especially spelt, under drought stress has been rarely investigated. Therefore, the aim of the present study was to examine the composition of fungal communities in the root endosphere and rhizosphere of three Triticum aestivum ssp. spelta L. cultivars and one Triticum aestivum ssp. vulgare L. cultivar, grown under drought and controlled conditions in different soil preparations. Culture-dependent fungal community profiling was performed to examine the impact of rhizocompartments (endosphere, rhizosphere), host genotype, watering status and different soil preparation on roots mycobiome structure. A total of 117 fungal strains, belonging to 22 genera, were found to colonize the internal and external parts of roots in T. aestivum ssp. spelta L. and T. aestivum ssp. vulgare L. cultivars. The results showed that the part of root and soil preparation type significantly determined the mycobiome composition of wheat roots.

“…The evolution of wheat consumption has been of interest to researchers for a long time [16,17], who have concluded that it is a main component of the human diet. However, concerns regarding the negative influence of its consumption through its derived products such as bread on health [18] or the environment [19] have increased.…”

Influencing Factors and Social Media Reflections of Bakery Products Consumption in Romania

et al. 2021

View full text Add to dashboard Cite

Bakery products, and bread specifically, represent an important part of the Romanian diet. Whether this situation is motivated by quality factors or by quantitative factors is an important aspect that needs to be investigated. In addition, the relation between peoples’ interest in a particular product such as bread during a crisis period should point out important characteristics of that population. Aiming at determining both the influencing factors of bakery product consumption and the importance given to this type of product in the media during a crisis, this empirical study highlights the profound connections between income level and the fear of not having food security for the people of a less developed country such as Romania. The study considers the use of both qualitative and quantitative methods to reach its objectives. The results point to a strong reliance of the respondents on cheap white-flour bakery products in their regular diet, and a significant increase in interest in bakery products during the COVID-19 pandemic.
