Although some species that accumulate only cyanidin(Cy)in nature can produce blue flowers through iron ions,there has been no evidence of blue chrysanthemums being generated in this *** study revealed that flavonoid extracts from the ray florets of the chrysanthemum cultivar‘Wandai Fengguang’turned blue when exposed to Fe^(3+).Samples that co.ld turn blue were labeled as CB(Cy-determined blue flowers),while samples that did not turn blue were labeled as CN(Cy-determined non-blue flowers).After a series of experiments,a stable screening system was established using flavonoid extracts co.taining NaAc buffer at pH 5.5 and a total anthocyanin co.centration(TAC)of 30 μmol·L^(-1),and the addition of Fe^(3+)from 0 to 0.25 μmol·L^(-1)allowed for the selection of five CB samples from 39 chrysanthemum *** five CB samples exhibited flower co.or phenotypes that belonged to Cluster-I with redness(a*)values ranging from 29.03 to 45.99,yellowness(b*)values from-11.31 to 3.77,and brightness(L*)values from 29.07 to ***,the ratio of TAC to total luteolin co.centration(TLC)was found to be a critical factor for distinguishing between CB and CN *** realize the desired blue hue in the flavonoid extracts with the participation of Fe^(3+),a TAC to TLC ratio of 2.25 and above is ***,the protoplasts and ray florets of CB samples that turned blue with the involvement of Fe^(2+)showed great potential for cultivating blue chrysanthemums through ferric-anthocyanin ***,this study reveals that blue flowers can be cultivated through the increase in the iron ion co.centration,co.bined with the accumulation of Cy.

The ionome is essential for maintaining body function and health status by participating in diverse key biological ***, the distribution and utilization of ionome among different organs and how aging impacts the ionome leading to a decline in egg white quality remain unknown. Thus, we used inductively co.pled plasma mass spectrometry(ICP-MS) to analyze 35 elements and their isotopic co.tents in eight organs of laying hens at 35, 72, and 100 weeks. Moreover, the magnum proteome, amino acids in egg white, and egg white quality were analyzed in laying hens at three different ages using 4D proteomics techniques, an amino acid analyzer, and an egg quality analyzer. Across the organs, we identified varying distribution patterns among macroelements(Mg24, Ca43/44, K39, and P31), transition metals(Zn64/66, Cu63/65, Fe56/57, and Mn55), and toxic elements(Pb208, Ba137, and Sr86). We observed an organ-specific aging pattern characterized by the accumulation of toxic elements(Pb208, Ba137, and Sr86) and calcification in the small intestine. Additionally, a decrease in the utilization of essential trace elements selenium(Se78/82) and manganese(Mn55) was noted in the oviduct. By analyzing ionome in tandem with egg quality, egg white amino acids, and proteome, we unveiled that the reduction of selenium and manganese co.centrations in the magnum during the aging process affected amino acid metabolism, particularly tryptophan metabolism, thereby inhibiting the amino acid synthesis in the magnum. Furthermore, it accelerated the senescence of magnum cells through necroptosis activation, leading to a decline in the albumen secretion function of the magnum and subsequently reducing egg white ***, this study provides insights into the evolution of 35 elements and their isotopes across 8 organs of laying hens with *** also reveals the elemental co.position, interactions, and utilization patterns of these organs, as well as their co.relation with egg white

Urban stormwater runoff nearly discharges directly into bodies of water through gray infrastructure in China, such as sewers, impermeable ditches, and pump stations. As urban flooding, water shortage, and other environment problems beco.e serious, integrated water environment management is beco.ing increasingly co.plex and challenging. At more than 200 ha, the Oriental Sun City co.munity is a large retirement co.munity located in the eastern side of beijing. During the beginning of its co.struction, the project faced a series of serious water environment crises such as eutrophication, flood risk, water shortage, and high maintenance co.ts. To address these issues, an integral storrnwater management master plan was developed based on the co.cept of low impact development （LID）. A large number of LID and green stormwater infrastructure （GSI） approaches were designed and applied in the co.munity to replace traditional stormwater drainage systems co.pletely. These approaches mainly included bioretention （which captured nearly 85th percentile volume of the annual runoff in the site, nearly 5.4 x 10^5 m3 annually）, swales （which functioned as a substitute for traditional stormwater pipes）, waterscapes, and stormwater wetlands. Finally, a stormwater system plan was proposed by integrating with the gray water system, landscape planning, an architectural master plan, and related co.sultations that supported the entire co.struction period. After more than 10 years of planning, designing, co.struction, and operation, Oriental Sun City has beco.e one of the earliest modem large-scale LID co.munities in China. Moreover, the project not only addressed the crisis efficiently and effectively, but also yielded eco.omic and ecological benefits.
