Summary: This study investigated the effects of freeze-thawed cycles and a new antifreeze protein on the structure and physicochemical characteristics of wheat starch. It was found that the addition of the antifreeze protein reduced the damage caused by ice crystals during freeze-thaw cycles, decreased retrogradation tendency, and improved the gel texture properties of freeze-thawed starch. This study provides new strategies for improving the quality of frozen starch-based foods.

Summary: Chilling injury is a barrier to kiwifruit refrigeration, but understanding the molecular basis of the cold response in refrigerated kiwifruit is crucial. The study identified 81 bZIP family proteins in kiwifruit and revealed that the expression of AREB/ABF family members is induced by low temperature and ABA. Ectopic expression of AchnABF1 enhances cold tolerance in plants and is involved in osmotic stress response.

Summary: This study investigated intraspecific variation in the effects of autumn warming on photosynthetic activity, photosynthetic pigments, and freezing tolerance in different provenances of Douglas-fir. The results suggest that autumn warming does not result in a downregulation of photosynthesis in Douglas-fir and does not impair freezing tolerance.

Summary: Arabidopsis and Chorispora bungeana show significant differences in nitrogen allocation, leaf nitrogen forms, and response to cold stress, with C. bungeana exhibiting increased leaf protein content and reduced nitrogen allocation under cold stress. Additionally, total free amino acid content in C. bungeana leaves is higher than in Arabidopsis when grown at warm temperatures, while cold treatment induces amino acid accumulation in Arabidopsis leaves. The two species also differ in the expression of nitrate transporter genes and activities of nitrate assimilation enzymes.

Summary: Plant size significantly influenced soil properties and microbial biomass at all elevations, with most parameters of soil nutrition and microbial biomass decreasing with elevation, while the relative interaction index increased. This indicates that soil amelioration by Thylacospermum caespitosum is dependent on plant size and increases with elevation in harsh alpine ecosystems.

Summary: This study investigated the abundance and community structure of nitrifying microorganisms in four alpine grasslands on the Qinghai-Tibetan Plateau. Different ammonia-oxidizing archaea, bacteria, and nitrite-oxidizing bacteria occupy distinct niches in response to factors such as soil pH, ammonium, and moisture, providing a theoretical basis for understanding the impact of grassland degradation on soil nitrifying communities in alpine ecosystems.

Summary: The study showed that organic compost-assisted Calendula officinalis phytoremediation for crude-oil contaminated soil was highly effective in the Loess Plateau, China. Compared to planting Calendula officinalis alone, the addition of organic compost and biochar significantly improved phytoremediation efficiency, and also enhanced soil physical-chemical characteristics and soil microbial communities.

Summary: B1L regulates lateral root initiation in Arabidopsis by mediating PIN recycling via exocytic vesicle trafficking. The b1l mutants exhibited increased lateral root primordium initiation, resulting in a higher number of lateral roots. The auxin signal was also stronger in the stage I lateral root primordia of b1l mutants. B1L interacts with the exocyst and is involved in regulating PIN exocytosis, thereby affecting polar auxin transport and lateral root development.

Summary: In this study, the hormone content, specific value, and carbohydrate and protein metabolism in buds and leaves of L. ruthenicum at different stages were investigated. The results showed that the hormone content and specific value exhibited different trends in buds and leaves. Higher levels of soluble sugar and sucrose in buds and leaves were beneficial to bud differentiation. Carbohydrate metabolism increased while nitrogen metabolism decreased from the open stage to the senescent stage.

Summary: Afforestation can significantly increase carbon sinks in terrestrial ecosystems and slow down global warming. This study used eddy correlation method to measure carbon and water fluxes and environmental factors in two artificial forests in the dryland of Northwest China. Results showed that the Larix principis-rupprechtii forest ecosystem had higher water use efficiency, light use efficiency, gross primary productivity, and ecosystem respiration compared to the Pinus tabulaeformis forest ecosystem. However, the P. tabulaeformis forest ecosystem had higher carbon sequestration efficiency. The CO2 and H2O fluxes in the L. principis-rupprechtii forest ecosystem were more sensitive to environmental factors, and the RECO was more sensitive to temperature changes.

Summary: Field pea is an important pulse crop and widely grown in North China. This study evaluated the grain yield and agronomic traits of 14 pea cultivars in irrigated and rainfed environments across seven locations. The results showed that genotype, environment, and genotype x environment interaction had significant effects on yield. GGE biplot analysis identified superior genotypes and productive environments. Among the tested genotypes, the semi-leafless pea variety Longwan 10 had the highest yield, and Yondeng, Qitai, Liaoyang, Dingxi, and Tangshan were the most productive regions.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.

Summary: Plants have evolved a mechanism called 'stress memory' to survive in various environmental stresses. This study reveals the physiological, biochemical, and molecular mechanisms underlying drought stress memory formation in cotton, highlighting the role of histone modification H3K4me3 in regulating transcriptional memory. It also investigates the intergenerational inheritance of drought stress memory in cotton, providing theoretical guidance for cotton breeding.
