Summary: This study phenotyped root traits in wheat using 10 pairs of near-isogenic lines targeting four genomic regions (GRs) and identified 15 putative candidate genes associated with different root traits. Among the candidate genes, UDP-glycosyltransferase (UGT)-encoding genes and leucine-rich repeat receptor-like protein kinase (LRR-RLK)-encoding gene showed important functions for root trait control in other crops. Further confirmation and validation of these candidate genes are needed for marker-assisted wheat breeding.

Summary: Source traits, such as photosynthesis, play a crucial role in enhancing crop yield potential. However, for a comprehensive understanding, the interactions of various processes in crop regulation, including sink activities, need to be considered. This review uses 'wiring diagrams' to integrate these interactions and examine the regulation of source traits at different stages of wheat development. The review also discusses challenges and opportunities in photosynthesis components due to canopy formation and the feedback regulation of source activity.

Summary: Regulation of wheat protein quality involves multiple metabolic pathways, with key enriched pathways including alanine, aspartate, and glutamate metabolism. Differentially expressed proteins or genes in amino acid synthesis pathways impact wheat quality, and ribosomes and the ER may play key roles in regulating glutenin synthesis. Real-time quantitative PCR analysis validated some differentially expressed proteins, confirming the transcriptome and proteomic results.

Summary: Breeding metribuzin-resistant wheat through genetic improvement is crucial for weed control in wheat production. A major QTL on wheat chromosome 4A has been identified as responsible for a significant portion of metribuzin resistance. Near-isogenic lines (NILs) play a key role in converting quantitative traits into Mendelian factors for better resolution of the QTL.

Summary: By reviewing the interacting processes determining sink strength and yield potential in wheat, and visualizing them in a set of 'wiring diagrams', the main traits determining sink strength were identified and research gaps were highlighted for achieving gains in sink strength. In the pre-anthesis phase, grain number could be increased through enhanced spike growth and improved fruiting efficiency. In the post-anthesis phase, grain sink strength could be augmented through manipulation of grain size potential and improving spike vascular architecture. The wiring diagrams provide a potential workspace for yield improvement in wheat and other field crops.

Summary: Overexpression of Glu-1Bx7 contributes to high dough strength and improving wheat quality, but wheat varieties containing Bx7(OE) are rare. In this study, four cultivars with 1Bx7(OE) were selected and crossed with Keumkang, resulting in increased expression of HMW-GS 1Bx7 in NILs. NIR spectroscopy analysis showed that NILs had higher protein content and SDS-sedimentation compared to Chisholm and Keumkang. This study suggests that crossbreeding with 1Bx7(OE)-containing cultivars can enhance the quality of domestic wheat.

Summary: Wheat genotypes resistant to powdery mildew have been developed and characterized in this study. Two near-isogenic lines were created, one with resistance to the disease and the other susceptible. Genetic and molecular marker analysis revealed that the resistance was associated with a specific gene locus, Pm5e. The two lines showed similar genomic compositions and performed similarly in yield-related and plant growth traits, indicating that Pm5e is a promising disease resistance gene in wheat breeding.

Summary: Drought is a significant challenge for wheat production and this study investigated the mechanism behind drought tolerance in wheat using proteomic analysis. The study identified 41 differentially expressed proteins related to drought tolerance and revealed important pathways involved in drought tolerance, such as transcription, translation, protein export, photosynthesis, and carbohydrate metabolism. Several candidate proteins responsible for drought tolerance were suggested, including 30S ribosomal protein S15, SRP54 domain-containing protein, auxin-repressed protein, serine hydroxymethyltransferase, and an uncharacterized protein.

Summary: Soil amendments are commonly used to reduce greenhouse gas (GHG) emissions by altering soil qualities, but the mechanism is still unclear. This study investigated the effects of biochar, Bacillus mucilaginosus, and Bacillus subtilis on soil properties, enzyme activities, soil microbes, and GHG emissions. Results showed that soil amendment addition decreased some enzyme activities and had little effect on soil microbes, except for those related to carbon and nitrogen cycles. BC, BM, and BS amendments reduced cumulative CO2 emissions, while N2O emissions varied. Overall, soil amendments decreased GHG emission intensity and global warming potential. Factors such as enzyme activities, Proteobacteria, Mortierellomycota, and Acidobacteriota were important in controlling GHG emissions. However, soil amendments alone had limited effects on the Loess Plateau, and combining biochar and plant growth-promoting rhizobacteria may be beneficial.

Summary: Climate change directly impacts the yield of vegetables through rising temperatures. Breeding for climate-resilient crops requires significant time and effort, but advancements in omics technologies have improved the efficiency of identifying pathways for high-temperature stress resilience in vegetable crops. Genomics-assisted breeding, gene editing, and speed breeding offer new approaches to develop temperature-resilient vegetables more efficiently. This review discusses the effects of heat stress on vegetables and highlights the use of omics and genome editing in producing temperature-resilient vegetables.

Summary: Identifying quantitative trait loci (QTL) for different root traits in bread wheat can help breeders develop climate-resilient and high-yielding wheat varieties. This study detected 14 QTL for eight root traits on nine wheat chromosomes and validated two QTL for shallow root depth and high root dry mass in independent populations. The identified QTL and candidate genes are valuable resources for future root trait improvement in wheat.

Summary: The accuracy of predicted breeding values (PBV) for low heritability traits can be increased by utilizing information from correlated traits. A study compared the accuracy of PBV for 10 correlated traits in a genetically diverse field pea population using univariate or multivariate linear mixed model (MLMM) analysis. The MLMM approach improved the accuracy of PBV and showed potential for increasing genetic gains in early generation selection cycles.

Summary: The two major concerns of sustainable agriculture are food security and climate warming. Straw incorporation is a commonly used field management measure, but its high carbon: nitrogen ratio poses issues. Ammoniated straw treatments aim to reduce the ratio, but studies on their long-term effects on maize grain yield and net greenhouse gas budget are limited.

Summary: Researchers improved crop yield projections by integrating a dynamic linear model (DLM) and a random forest machine learning model (RF) with global gridded crop models (GGCM). The RF+GGCM models showed higher accuracy and reduced uncertainties compared to using GGCM alone. The main influencing factors for maize yield were chilling days, crop pests and diseases, and drought, while for soybean, they included crop pests and diseases, tropical days, and drought. This study provides a robust framework to assess the impact of future climate change on crop yields.

Summary: The role of abundant and rare bacterial taxa in maintaining bacterial community stability is controversial. Rare taxa have higher diversity and modularity than abundant taxa. The diversity of rare taxa is negatively correlated with bacterial community differences, while no correlation exists between abundant taxa and community differences. Highlighting the importance of rare species is crucial for maintaining bacterial community stability.
