Summary: Pyramiding useful QTLs into an elite variety is a promising strategy for developing tolerant varieties against multiple abiotic stresses. However, testing the functional compatibility of different QTLs, such as Pup1 and Sub1, is crucial for ensuring their effectiveness in the target variety. In this study, it was found that while Pup1 and Sub1 were functionally compatible under submerged conditions, they exhibited incompatibility under P-non-supplied conditions, suggesting the need for further investigation into the underlying mechanisms.

Summary: Waterlogging is a growing threat to wheat production in high-rainfall areas. This study identified three quantitative trait loci (QTL) associated with waterlogging tolerance in wheat and developed markers for marker-assisted selection (MAS) to improve waterlogging tolerance. These findings are of great importance for enhancing waterlogging tolerance in wheat.

Summary: Cold tolerance in maize is limited and breeding for cold tolerance remains a challenge. In this study, we identified QTL associated with cold tolerance during germination and seedling stages. Our results showed a large genetic diversity in cold tolerance within the studied populations. We found several QTL related to plant weight, fluorescence, and chlorophyll content under both cold and control conditions. However, the number and location of QTL differed between these conditions, suggesting a significant genetic discrepancy between optimal and low temperatures. Further studies are needed to identify favorable alleles with significant effects on cold tolerance in maize using different experimental designs.

Summary: In this study, a stable QTL qSalt-A04-1 for salt tolerance in cotton seed germination stage was identified, along with two candidate genes, GhGASA1 and GhADC2, playing negative roles by modulating GA and PA signalling pathways. Functional analyses showed that GhGASA1 and GhADC2-overexpression lines were more sensitive to salt stress than wild-type Arabidopsis, indicating their potential as promising candidates for salt tolerance improvement in cotton.

Summary: Understanding the molecular mechanisms of resistance and tolerance to pathogen infection can help in developing novel interventions. A study on mice infected with Salmonella Typhimurium found distinct phenotypes of delayed susceptible, tolerant, and resistant strains. Tolerant strains showed lower preinfection core body temperatures, rapid disruption of body temperature postinfection, higher neutrophil levels, and more severe tissue damage compared to resistant strains. Gene analysis identified specific genes associated with tolerance and resistance, particularly fibrinogen genes.

Summary: Flooding stress is a major threat to soybean crops, affecting their growth, yield, and quality. Recent advancements in molecular breeding, such as QTL mapping, transcriptome analysis, and CRISPR/Cas9, have provided valuable insights into the molecular mechanisms of flooding tolerance in soybean. Conventional breeding methods and agronomic practices also play a role in developing flood-tolerant soybean cultivars.

Summary: The study characterized a rye mutant with high lodging resistance, tall posture, and high biomass production by examining its stem vascular bundles, sclerenchyma composition, and chemical features associated with lodging resistance. The findings suggested that the superior culm stability of the mutant was attributed to a combination of increased vascular bundles, more sclerenchyma, and features like elevated lignin and xylan levels. The mechanical stability and unique culm properties identified in the study may be valuable for breeders seeking to enhance lodging resistance in tall posture cereal crops.

Summary: This study explores the mechanisms of rice tolerance to salinity stress, identifying 26 QTLs related to salinity tolerance through a genome-wide association study on 179 Vietnamese rice landraces. Ten of these QTLs were associated with multiple traits, suggesting pleiotropic effects in controlling plant responses to salinity stress.Twenty-one of the identified QTLs colocalized with known QTLs, and the associated genes mainly function in gene regulation, signal transduction, or hormone signaling related to salinity stress tolerance.

Summary: This study evaluates the climate sensitivity and growth patterns of the Moroccan fir Abies marocana, and finds a negative effect of warming on tree growth. Genetic differentiation is weak between the studied populations, and growth trends and tree size are associated with genetics rather than climatic sensitivity. The findings highlight the potential of tree rings and genome-wide analysis in understanding the adaptive capacity of drought-sensitive forests.
