Summary: The resistance of Huaidao5 is due to the high constitutive expression of tolerance genes, while that of Huaidao9 is derived from the induced resistance to cold in flag leaves and panicles. Through transcriptome analysis, we identified differentially expressed genes and co-expression networks associated with cold tolerance in reproductive-stage rice. Our findings provide insights into the mechanisms of cold tolerance in rice and identify candidate genes related to cold response and tolerance.

Summary: The auxin receptor plays a significant role in the plant auxin signalling pathway in response to abiotic stress. Through a microarray study on transgenic rice overexpressing ABP57, researchers identified 12 modules of highly related genes that are involved in specific responses to drought or other abiotic stress types. Gene set enrichment analysis highlighted modules related to transmembrane transport of metal ions and response to oxidative stress as being highly upregulated. The integration of co-expression information with physical interaction data identified 123 hub genes. Additionally, the interplay between the metabolism pathways of chlorophyll and flavonoid and the signalling pathways of MAPK, IAA, and SA suggested their concurrent involvement in stress tolerance response.

Summary: The study highlighted the divergence in gene expression patterns between the drought-tolerant variety Nagina 22 and the drought-sensitive variety IR64 in response to drought stress. The differentially expressed genes in Nagina 22 were associated with drought-related QTLs and plant traits, while some genes showed opposite regulation in the two rice varieties under similar drought conditions, possibly due to sequence variations in their promoter regions.

Summary: In this study, we investigated the effects of drought stress at different stages of the rice life cycle on yield performance and gene expression. We found that drought stress during the seedling and reproductive stages reduced yield by affecting seed number and setting rate. We also observed that rice plants respond to drought stress through two signaling pathways, allowing them to adapt to changing soil water conditions. Furthermore, prolonged drought stress delayed flowering in rice through the regulation of specific genes.

Summary: This study explores the potential of the CERES-Rice model as a decision support tool (DST) in identifying drought-tolerant high-yielding upland rice genotypes. The experiments conducted showed that the model accurately predicted grain yield under different irrigation treatments and the identified genotypes had lower stress indices and higher water use efficiency, indicating their drought tolerance. The results support the use of the model as a DST in rice breeding programs for selecting drought-tolerant high-yielding genotypes.

Summary: Optimum growing temperature is crucial for maximum crop yield. This study evaluated the effect of heat stress on agronomic and physiological attributes of Green Super Rice (GSR) at the flowering stage. Genotypes showed significant variations in all studied parameters except normalized difference vegetative index (NDVI). Heat stress significantly affected grain yield, plant height, straw yield, harvest index, and cell membrane stability in most genotypes. Outperforming NGSR-16 and NGSR-18 under heat stress suggests their potential as parent lines for developing heat-tolerant rice.

Summary: The manufacture and production of industrial chemicals continues to increase, leading to widespread population exposures and resultant health impacts. Low-wealth communities and communities of color often bear disproportionate burdens of exposure and impact. Multiple authoritative bodies and scientific consensus groups have called for actions to prevent harmful exposures via improved policy approaches. We developed consensus recommendations for health-protective, scientific approaches to reduce harmful chemical exposures, which can be applied to current US policies governing industrial chemicals and environmental pollutants.

Summary: This review analyzes the impacts of Cd on seed germination and seedling vigor and the use of priming agents to mitigate these impacts. Results show that seed endurance to Cd exposure varies among species, with some seeds maintaining or improving their germination and vigor. Factors influencing seed tolerance include temporal variations in anatomical, physiological, and biochemical features. Cd can also have transgenerational effects on plants by affecting seed endophytes, provisioning of resources and regulatory elements, and seed (epi)genomics. Different priming agents can mitigate Cd-induced impacts on seeds, sometimes even enhancing their performance. Overall, understanding plant tolerance mechanisms against Cd pollution is important for breeding programs, agriculture, and environmental policies.

Summary: Breeding staple crops with higher micronutrient concentration is a sustainable solution for addressing micronutrient malnutrition. In this study, we employed Multi-Cross QTL analysis and Inclusive Composite Interval Mapping to analyze 11 agronomic, yield, and biofortification traits in rice. We found a total of 156 QTLs for agronomic and biofortification traits, with some important QTLs identified for zinc (qZn(5.2)), iron (qFe(7.1)), and grain yield (qGY(10.1)). These QTLs can be utilized in genomic-assisted breeding of rice. We also identified 26 QTL clusters on different chromosomes, and many of the QTLs co-located with functionally related candidate genes, indicating the accuracy of the QTL mapping.

Summary: This study aimed to evaluate the effect of different selenium application methods (soil or foliar) and sources (organic or inorganic) on the total selenium content and speciation in selenium-enriched soybean grains. The results showed that all treatments with inorganic selenium increased the selenium content in grains compared to the control. More than 80% of the total selenium was present as selenomethionine (SeMet), and the speciation was influenced by the selenium source and application method. The treatments using inorganic selenium, applied via soil or foliar, produced the highest content of SeMet in soybean grains. Finally, the preservation of selenium species in products derived from soybean grains should be evaluated.

Summary: The standard practice of initiating flowering in medicinal cannabis by reducing the photoperiod may not be suitable for all varieties. This study aimed to explore the effect of different flowering photoperiod treatments on biomass yield and cannabinoid concentration in three medicinal cannabis varieties. The results showed that starting with a 14-hour light/10-hour dark photoperiod resulted in the highest flower biomass yields for all varieties. However, a static 14-hour light/10-hour dark period caused a significant decrease in THC concentration in high THC varieties, while leading to a significant increase in CBD concentration in the high CBD variety.

Summary: Leaf oil terpenes in tea tree exhibit discrete phenotypes of adaptive and economic significance, and a genome-wide association study revealed that a supergene accounts for the chemotypes in Melaleuca alternifolia. A cluster of monoterpene synthase genes explained the variation in key monoterpenes, and chemotype-dependent null alleles provided an explanation for the genetic architecture underlying the chemotypes. This genetic model with three haplotypes explains the six terpene chemotypes and is supported by available cross-segregation data.
