Summary: The aim of this study was to assess the impact of water deprivation on root traits and to determine if the wheat cultivars Spica and Maringa could be useful for genetic analysis of root traits. Plants were grown in two different soils under well-watered and water-limited conditions. The analysis of root traits included length, nodal root number, thickness, and nodal root angle. The differences in root traits between Spica and Maringa were found to be consistent under different water and soil conditions. The results suggest that phenotyping under well-watered conditions is relevant for identifying traits related to water use efficiency, and Spica and Maringa are suitable as parental germplasm for studying the genetics of key root traits.

Summary: Plant species in arid regions have developed novel leaf features to collect atmospheric water, and a similar mechanism can be found in wheat plants. This study evaluated the leaf rolling dynamics among wheat genotypes and their relationship with moisture harvesting. The results show that leaf rolling type affects water use efficiency and soil moisture difference. The wetting property of the leaf surface is positively associated with atmospheric water collection.

Summary: Selection for root traits in crop breeding programs must consider the spatial and temporal interactions between root systems, the soil environment, and management practices. The success of selected traits in heterogeneous target environments depends on nutrient and water distributions and dynamics. Therefore, breeding efforts and farmer selection of genotypes should take into account the specific context in which the genotypes will be deployed.

Summary: Studies suggest that drought priming can enhance wheat's tolerance to drought, with the root apex playing a crucial role in this process. Drought priming augments root growth under drought conditions by regulating the levels of protective proline and glycine betaine. Further investigations reveal that different zones of the root apex exhibit varying responses in gene expression.

Summary: This study conducted a genome-wide association study (GWAS) on a wheat panel consisting of bread wheat varieties and introgression lines (ILs). They identified 17 stable quantitative trait nucleotides (QTNs) located on different chromosomes that explained up to 21% of the phenotypic variation. Comparative analysis of wheat genotypes revealed that ILs with a specific haplotype had significantly higher gluten content than those with a different haplotype. The newly identified locus on chromosome 2A inherited from T. timopheevii can be used to improve the quality traits of bread wheat.

Summary: Strategies to reduce drought damage in agriculture are urgently needed due to intensified climate change. The use of nanomaterials (NMs) to enhance plant resistance has shown promising results. In this study, the addition of 10 mg kg(-1) manganese ferrite (MnFe2O4) NMs significantly improved rice biomass, photosynthesis, nutrient elements, and polysaccharide levels under drought stress. The internalization of MnFe2O4 NMs by rice plants contributed to their ability to cope with drought. Furthermore, the introduction of MnFe2O4 NMs upregulated drought-sensing and receptor genes in the roots, leading to the synthesis of important compounds that helped plants withstand drought stresses and improved the nutritional quality of rice grains. This study provides valuable insights for developing nano-enabled strategies to enhance crop productivity and resilience against climate change.

Summary: This study analyzed the effect of residual plastic film (RPF) content on soil properties and crop yield in 15 counties in northern China through sampling and survey questionnaire. The main factors affecting RPF content were found to be plastic film mulching years, government recycling policy, spacing between rows, and recycling methods. The accumulation of RPF was found to aggravate soil salinization and reduce crop yields.

Summary: Developing deep roots is important for trees in drylands to resist drought, but its impact on photosynthesis is not fully understood. An experiment on an apple tree plantation in China showed that deep soil water deficit led to severe water stress and significantly reduced stomatal conductance, photosynthesis rate, and transpiration rate. However, nonstomatal limitation did not differ between treatments, indicating that deep soil water deficit affects photosynthesis mainly through reduced stomatal conductance rather than damaging the photosynthetic apparatus.

Summary: Genome editing can be used to domesticate orphan crops by editing their genomes. This technique shows promise in increasing agricultural output, especially in crops that possess undesirable traits similar to their wild cousins. By applying knowledge from model crops to orphan crops, breeders can quickly generate desired genetic diversity and innovative breeding materials. This review highlights the practicality of genome editing as a tool to accelerate the domestication of semi-domesticated or wild plants, providing a more diverse foundation for future food and fodder supplies. It also emphasizes the importance of investing in research to advance our understanding of plant genomes, genes, and cellular systems. Planting more of these abandoned orphan crops could help mitigate food shortages in the face of future climate crises.

Summary: Soybean plays a critical role in global food security and sustainability, but the interaction between soil nitrogen supply and nitrogen fixation throughout the growing season is poorly understood. This study evaluated the relationship between nitrogen uptake and dry matter, described seasonal changes in soil-plant nitrogen dynamics among genotypes with different genetic backgrounds, and assessed the influence of soil NO3 and NH4 on temporal nitrogen fixation changes. The findings showed that nitrogen uptake from the soil had a greater impact on total nitrogen status than fixation. NH4 exposure and delayed NO3 availability suppressed end-season nitrogen fixation, highlighting the importance of soil nitrogen sources in soybean growth.

Summary: This study investigates the effects of two types of biochar (wood biochar and poultry biochar) on the growth and physiology of tomato seedlings under drought and salinity stress. The results show that biochar addition effectively improves the root water potential and osmotic potential of tomato plants, and significantly improves the leaf relative water content. Furthermore, biochar application reduces the concentration of abscisic acid in xylem sap under drought and salinity stress.

Summary: Global climate variations cause extreme temperatures and reduce crop production, resulting in food insecurity worldwide. Temperature extremes, such as chilling (0-15 degrees C) and freezing (<0 C), severely affect plant growth and physiology. Plants respond to these stresses by activating various endogenous mechanisms, including phytohormone biosynthesis, to tolerate and adapt to stressful environments. This review highlights the importance of phytohormones in regulating plant responses to cold stress and discusses the potential of genetic engineering and omics approaches to develop cold-smart crop plants.
