The widespread use of plastics has led to the prevalence of microplastics in the soil environment，which，as an emerging pollutant，affects plant growth，soil physicochemical properties，and microbial community structure. The effects of different contents of low-density polyethylene microplastics（LDPE-MPs）on soybean growth，soil physicochemical properties，soil enzyme activities，and microbial activities were investigated through pot culture experiments to explore the toxic effects of microplastics on soybean-soil-microbial systems. The results showed that compared with that in the control，microplastics inhibited soybean emergence（14.1%-25.0%），whereas plant height，biomass，and pod weight were inhibited by low concentration and promoted by high concentration，and SPAD of soybean was significantly reduced by high concentrations of microplastics stress. Microplastics affected the quality of soybeans，with s-sugars，s-proteins，and cellulose increased by 117.7%-258.8%，3.7%-61.6%，and 47.8%-83.4%，respectively，compared with those in the control. Microplastic addition also affected soybean nutrient uptake，as evidenced by the promotion of N（95.1%-144.4%）and P（4.1%-20.4%）uptake in the aboveground portion of soybeans and N（11.4%-19.4%）and P（8.5%-42.6%）uptake in the below-ground portion of soybeans，and inhibited K（2.2%-15.3%）uptake in the aboveground portion of the plant and K（3.9%-9.4%）uptake in the below-ground portion of the plan，respectively. The addition of microplastics had little effect on soil pH;however，it significantly increased CEC（65.1%-74.7%）and SOM（22.6%）. With the increase in the addition content，the content of NO3−-N，AP，AK，and UE activities were significantly reduced;the content of NO3−-N，AP，and AK was reduced by 57.7%，22.0%，and 18.8% compared with that in the control at 3% addition，respectively;and UE activity was inhibited by 13.98%. Further，16S rRNA sequencing analysis showed that microplastic stress increased the abundance of the Proteobacter group and reduced the abunda

Sexual maturation heterosis has been widely exploited in animal crossbreeding. However, the underlying mechanism has been rarely explored in chicken. In the present study, we performed the reciprocal crossing between White Leghorn and Beijing You chicken to evaluate the phenotypes related to sexual maturation,and profiled the ovary circRNAs of purebreds(WW, YY) and crossbreds(WY, YW) to elucidate the molecular mechanism underlying heterosis for sexual maturation. Pubic space and oviduct length exhibited positive heterosis,and age at first egg(AFE) exhibited negative heterosis in the crossbreds. We identified 3,025 known circRNAs and 624 putative circRNAs, which were mainly derived from the exons. Among these circRNAs, 141 and 178circRNAs were specially expressed in WY and YW, respectively. There were 52.38 and 64.63% of total circRNAs in WY and YW exhibited non-additive expression pattern, respectively. GO enrichment and KEGG pathway analysis showed that the host genes of non-additive circRNAs were mainly involved in TGF-beta signaling pathway, oocyte development, ATPase activator activity, oocyte meiosis, progesterone-mediated oocyte maturation and GnRH signaling pathway. Weighted gene co-expression network analysis identified that 4 modules were significantly(Pdevelopment, indicating that the non-additive circRNAs involved in the formation of sexual maturation heterosis through regulating genes related to the reproductive and developmental process. The findings would provide a deeper understanding of the molecular mechanism u
