Summary: Drought is a major limitation for sustainable agricultural production, particularly affecting the quality and quantity of bread wheat yield during flowering. Through studying contrasting wheat cultivars, it was found that the sensitive cultivar showed ineffective water management and a decline in photosynthesis, while the tolerant cultivar used photorespiration to dissipate excessive light energy and induced superoxide dismutase for a less inhibited photosynthesis. The tolerant cultivar also exhibited a more stable gluten profile and accumulation of specific proteins, indicating its potential as a marker for drought tolerance in breeding.

Summary: The continuous increase in global population drives the need for increased wheat production. Future wheat breeding will heavily rely on dissecting molecular and genetic bases, which is possible through the discovery of QTLs in constructed populations. The evaluation of 92 RILs in this study aimed to search for novel and stable QTLs in wheat.

Summary: Abiotic stress factors in production lands affect both the yield and quality traits of bread wheat. Increasing water table depths have a positive impact on quality traits, while increasing groundwater salinity levels result in decreased hectoliter weight, fat ratio, starch ratio, and NDF values, and increased protein content, sedimentation value, wet gluten content, ash ratio, and ADF values.

Summary: This study characterized the genetic variability of wheat root architecture by measuring the root and shoot traits of durum and bread wheat varieties. Significant correlations were found between root traits and field agronomic performances, suggesting that investing more resources in roots improved water and nutrient uptake and wheat yield. Genetic analysis identified quantitative trait loci (QTLs) for root traits, some of which colocalized with QTLs for field traits in certain environments. Breeding efforts have resulted in deeper rooting and fewer seminal roots in bread wheat, while the number of tillers has increased in bread wheat but decreased in durum wheat. Breeding for root traits could help maintain current yield and adapt to specific drought scenarios.

Summary: This paper proposes a new pathway to assess the genetic variation of wheat germplasm using multidimensional traits derived from digital images. A machine vision platform is established to reconstruct 3D models of wheat germplasm, and multidimensional traits are extracted from the models. The results demonstrate that extracting multidimensional traits from digital images is a promising high-throughput and cost-efficient approach for assessing genetic variation in wheat germplasm.

Summary: Water scarcity is a major environmental stress that negatively affects the growth, production, and quality of wheat. The study found that drought stress significantly reduced wheat yield and photosynthetic efficiency, but increased antioxidant enzyme activities and proline content. Through hybrid analysis, some parental genotypes and combinations were identified with good potential for improving drought resistance and yield traits in wheat. Additionally, certain physiological traits were found to be important for indirect selection of wheat under water deficit conditions.

Summary: Climate change and emerging water scarcity pose serious threats to rice production systems. Developing drought tolerant genotypes is crucial for ensuring food security. A trial was conducted to identify drought tolerant rice genotypes with high grain yield potential. Results showed that hybrids of Azucena x Giza177 and Azucena x Giza179 exhibited superior traits such as maximum leaf diffusive resistance, leaf transpiration rate, and grain yield. In contrast, IRAT112 x N22 and IRAT112 x Azucena hybrids had the lowest stomatal conductance. Promising general combiners for drought tolerance and better grain yield were also identified, including three parents: N22, Azucena, and Giza179. These findings could contribute to future breeding programs for increased drought tolerance. Furthermore, certain hybrid combinations showed good effects and significant heterosis, indicating their potential for drought introgression.

Summary: Plant hybridization is essential for breeding new varieties with desired traits. This study aimed to evaluate gene action, heritability, and heterosis of various traits in rice under water deficit conditions. Crossing four different water-deficit tolerant rice genotypes produced populations with improved performances and adaptability to water deficit condition. The study also identified different types of gene interactions influencing the inheritance of specific traits. The findings provide valuable insights for future phenotypic and genotypic association studies in rice and for developing water deficit tolerant rice cultivars.

Summary: Abiotic stress reduces crop production worldwide. To recommend suitable genotypes for cultivation under water deficit and heat stress conditions, understanding the genetic basis and plant responses to these stresses and their interactions with the environment is crucial. In this study, the MGIDI index was used to identify abiotic-stress-tolerant wheat genotypes, while the WAASB and WAASBY indices were used to recognize high-yielding and stable genotypes. Twenty wheat genotypes were evaluated for their abiotic stress tolerance under various test conditions, and certain genotypes showed slight reductions in measured traits compared to the control group. The genotypes G12 and G17 were found to be the most stable candidates based on different indices, indicating their potential for improving productivity and stabilizing grain yield under optimal, water deficit, and heat stress conditions.

Summary: In Saudi Arabia, the concentration of Pepper mild mottle virus (PMMoV) and human adenovirus (HAdV) in wastewater treatment plants was measured. PMMoV was found in 94% of wastewater samples with concentrations ranging from 62 to 3.5 x 10(7) genome copies/l, while HAdV was detected in 75% of raw water samples with concentrations ranging from 1.29 x 10(3) GC/L to 1.26 x 10(7) GC/L. A higher positive correlation between PMMoV and HAdV concentrations was observed at one of the treatment plants.

Summary: Abiotic stress caused by heavy metals has a negative impact on plant growth, especially in crop plants, which affects grain yield and sustainable food security. Excessive copper availability impairs plant growth and reproductive performance. Hydrogen peroxide plays a role in mitigating oxidative damage caused by biotic or abiotic stress, but its influence needs further quantification. This study investigated the effects of hydrogen peroxide on the growth, grain yield, and copper uptake of stressed wheat, and found that foliar application of hydrogen peroxide improved growth and yield traits under copper stress.

Summary: Acute gastroenteritis is a common illness in Saudi Arabia, but the contribution of human rotavirus A (HRV) and human adenovirus (HAdV) strains to this condition is unclear. This study investigated the prevalence and genotypes of HRV and HAdV using PCR, sequencing, and phylogenetic analysis. It was found that HAdV had a higher prevalence than HRV, with HAdV infections more common in females and HRV infections only detected in males. The prevalence of HAdV peaked in autumn and was positively correlated with humidity. The dominant strains of HAdV were type 41 and the G2 lineage of HRV.

Summary: Direct drum seeding is a viable alternative to transplanted rice, addressing labor and water scarcity issues. However, weed infestation is a major concern, necessitating efficient weed management practices. An experiment in India showed that early sowing and mechanized conoweeding or sequential herbicide application resulted in higher yields and effective weed control.
