Summary: The study found that parental water-deficit stress has a positive impact on traits such as harvest index and protein content in the progeny of durum wheat. Integrated analysis using three omics platforms revealed potential pathways involved in transgenerational stress tolerance, including hormone signaling and nutrient metabolism. This study provides insights into key miRNA-mRNA modules that could be candidates for transgenerational stress improvement in durum wheat.

Summary: The study showed that priming cowpea plants with drought stress could help alleviate subsequent drought stress during the later growth stage, resulting in improved water status, photosynthesis, water productivity, and yield. Primed plants consumed less water and had higher water use efficiency, suggesting that drought priming could be a promising strategy to save water for irrigation while improving water productivity in regions with limited water resources.

Summary: This study analyzed the physiological responses and transcriptome changes of two soybean varieties under drought stress. The results showed that the drought-tolerant variety had smaller stomata, higher ABA content, and better water use efficiency. Additionally, it had fewer differentially expressed genes and specific pathways related to drought tolerance. This study deepened our understanding of the drought resistance mechanisms in soybeans and provided valuable references for breeding drought-resistant soybeans.

Summary: Green light partially replacing red light and blue light improves drought tolerance in cucumber seedlings by promoting the synthesis of GABA and upregulating the expression of the CsGAD2 gene. This study highlights the role of green light in plant physiological processes and suggests that analyzing the function of green light in improving drought tolerance could lead to new approaches for enhancing plant stress resilience.

Summary: Nocturnal stomatal conductance (g(sn)) is a significant source of water loss, with variations in magnitude and responses across different wheat genotypes. Higher g(sn) in the wild relative was associated with lower nocturnal respiration and higher daytime CO2 assimilation, while both species exhibited declines in g(sn) post-dusk and pre-dawn. The intraspecific variation in g(sn) and its correlation with daytime stomatal conductance (g(s)) present opportunities for exploiting intrinsic variation under heat or water stressed conditions.

Summary: Durum wheat, a commonly cultivated species, plays a crucial role in the human diet as it is used to produce various foods. However, drought and soil salinity stress can lead to reduced yield and grain quality. Plants have evolved antioxidant mechanisms to counteract oxidative damage caused by stress, with enhancement of the antioxidant defense system improving tolerance to hyperosmotic stress.

Summary: Understanding sorghum response to water stress at different developmental stages is crucial for improving drought tolerance in sorghum varieties. This study aimed to characterize the agro-physiological responses and water use of sorghum under different drought scenarios. The experiment used a DroughtSpotter facility to track real-time water use. The results showed that DS2 had a greater impact on green leaf number and plant leaf area, but delayed flowering compared to DS1. Moreover, DS2 had taller plants and higher biomass production. However, DS1R and WW treatments outperformed both DS1 and DS2 in terms of grain yield. Transpiration and photosynthetic rates decreased concurrently with stomatal conductance, indicating stomatal down-regulation. However, the increase in intercellular CO2 concentration suggested a non-stomatal limitation of photosynthesis. Overall, DS2 had higher water use efficiency compared to WW and DS1 treatments, highlighting the importance of avoiding drought stress during the critical stage of growing point differentiation for better yield and water use efficiency.

Summary: In order to sustain high alfalfa production with limited water, cultivars with improved water use efficiency (WUE) are needed. Through greenhouse experiments, the collection River side (RS) was identified as having greater WUE under drought than other accessions, possibly due to its stomatal sensitivity to abscisic acid (ABA).

Summary: In this study, the effects of drought and heat stress on thermotolerance in durum wheat were investigated. The results showed that drought priming could induce the acquisition of thermotolerance in most cultivars. Proline accumulation and activation of heat shock proteins expression were also correlated to thermotolerance.

Summary: Durum wheat is a staple crop in the Mediterranean diet, prized for its adaptability and nutritional value. Environmental stresses such as water deficit and soil salinity can affect the protein and starch composition in durum wheat, in turn impacting yield and quality. Recent studies have discussed the effects of these stresses on various nutritional and health-related components in durum wheat grains.

Summary: The current social context emphasizes the need for increased food production, improved quality, and sustainable agricultural systems. Technological innovation, such as precision farming and variable rate techniques, can contribute to achieving these goals. This study incorporated soil property maps into nitrogen balance calculations for variable rate nitrogen fertilization of durum wheat. The results showed that variable rate techniques reduced nitrogen fertilizer use by 25%, while maintaining the same level of yield. Additionally, the crop response to variable rate application showed higher grain protein content and improved nitrogen use efficiency, indicating lower environmental impact and higher economic profitability.

Summary: Through gene expression and histological analysis of dehiscent and indehiscent pods, a potential candidate gene controlling pod indehiscence was identified. Pod shattering is associated with the lack of a functional abscission layer in the ventral sheath, and key anatomical modifications related to pod shattering occur early in pod development. Loss of pod shattering in legumes is proposed to result from histological convergent evolution and selection at orthologous loci.

Summary: This study aimed to identify candidate traits for pre-breeding in spring wheat to improve nutrient accumulation and early vigor at high latitudes. Whole-plant relative growth rate was found to be correlated with leaf area productivity and plant nitrogen productivity, while total leaf area was suggested as a candidate trait for improved nutrient accumulation and early vigor. Different root system traits were identified as relevant for the accumulation of different nutrients, highlighting the importance of specific root traits in wheat breeding for improved nutrient uptake.

Summary: Quinoa is a genetically diverse crop that can tolerate abiotic stresses and has gained popularity due to its high nutritional content. The coastal lowland ecotype of quinoa is of interest for cultivation in higher latitudes. A field experiment in Chile showed that some lines of coastal lowland self-pollinated (CLS) quinoa had higher yield and seed size than the commercial cultivar Regalona, even under reduced irrigation. Proximal sensing methods, such as thermal and hyperspectral imaging, were used to estimate plant water use and differences in photosynthesis among the lines.
