To explore the influence of different doses of Cu in BP, and its effects on the metabolism, gut microbiota and the transmission of antibiotic-resistant genes (ARGs) in SP through vertical transmission, this study analyzed the effects of varying Cu doses on BP milk microbiota, along with serum and fecal Cu content, gut microbiota composition, and ARGs in SP. The findings revealed that sufficient Cu improved the average daily feed intake of BP. Dietary Cu supplementation affected its content in BP milk, serum, and feces, as well as Cu content in SP serum and feces. Importantly, Cu significantly altered the microbiota composition in BP milk, and ileum microbiota was reshaped in SP correspondingly. Furthermore, Cu markedly increased ARGs in SP, particularly in the T16 treatment group (basal diet supplemented with 16 mg/kg Cu), where higher abundances of <em>arlR</em>, <em>cdeA</em>, <em>dfrL</em>, <em>efrA</em>, <em>optrA</em>, and <em>lsaE</em> were observed. Correlation analysis showed that <em>Lactobacillus</em> and <em>Escherichia-Shigella</em> in BP milk were negatively and positively associated with <em>Streptococcus</em> and <em>Clostridium</em> in SP ileal mucosa samples.

In this study, a comprehensive meta-analysis has been conducted, integrating 1220 paired observations from 64 publications, with a particular focus on comparing the effects of non-biodegradable (Non-bio) and biodegradable (Bio) MPs. Additionally, a machine learning approach has been developed to predict these impacts and identify key contributing factors. Our dual-method approach enables a more precise and comprehensive assessment of MPs’ ecological consequences in soils. The findings revealed that Non-bio MPs reduced microbial diversity by 6.95 % but increased microbial biomass and altered community structure by 15.05 % and 55.76 %, respectively.

Boosted Regression Tree (BRT) analysis identified soil properties (TN, TC, SOC, pH) and MPs characteristics (polymer type, size and concentration) as key drivers of microbial responses. Although Random Forest models achieved reasonable accuracy in predicting the impacts of MPs on microbial diversity and community structure, they performed poorly in predicting microbial functions due to complex and varying enzyme responses.

However, the mechanisms by which E3 ligases regulate rice immunity remain largely unclear. A previous study identified OsFBX388 as an E3 ligase that negatively regulates rice blast resistance. Here, we demonstrate that OsFBX388 interacts with OSK25 via its N-terminal F-box domain, thereby is a component of the SCF complex. Using its C-terminal domain, OsFBX388 targets OsHIPP56, a heavy metal-associated isoprenylated plant protein, for ubiquitination and degradation by the 26S proteasome. Meanwhile, knockout of <em>OsFBX388</em> or overexpression of <em>OsHIPP56</em> leads to substantial accumulation of OsHIPP56. Moreover, <em>OsHIPP56</em> overexpression enhances resistance to multiple blast fungus strains and to bacterial blight without compromising yield. The HMA domain of OsHIPP56 is structurally similar to the integrated domains (IDs) of the sensor NLRs RGA5 and Pikp-1, which recognize the MAX effectors AvrPia and AvrPik-D from the blast fungus, respectively. We found that OsHIPP56 interacts with both AvrPia and AvrPik-D. Notably, AvrPia and AvrPik-D are also targeted by OsFBX388 for ubiquitination and degradation by the 26S proteasome. The interactions between OsHIPP56 and these MAX effectors accelerate the OsFBX388-mediated degradation of both OsHIPP56 and the MAX effectors. Furthermore, OsHIPP56 interacts with the HMA domains of the NLR receptors RGA5 and Pikp-1. Co-expression of OsHIPP56 with the NLR pairs RGA4/RGA5 or Pikp-1/Pikp-2 triggers cell death in rice protoplasts. Collectively, these findings reveal a coordinated regulatory mechanism in rice immunity, where an E3 ligase mediates the ubiquitination of both a host target and pathogen effectors.</div></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"4 1","pages":"Article 100123"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146039606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
