In this study, a long-term field assessment was conducted to evaluate the ecological effects of glufosinate-tolerant GM zoysiagrass (<i>Zoysia japonica</i> Steud.; events JG21 and JG21-MS1) on non-target arthropod communities at two geographically distinct living modified organism isolation sites in South Korea (Jeonju and Seogwipo). A total of 528,796 arthropods were collected and classified into three functional groups: pests (45.73%), natural enemies (14.51%), and other arthropods (39.76%). Arthropod community composition exhibited clear regional and temporal variations. Linear mixed-effects model (LMM) analyses indicated that arthropod abundance and diversity indices were primarily influenced by the year and region, whereas treatment effects, defined as differences between GM events and non-GM controls, were not significant. Although occasional statistical differences were detected, post hoc comparisons confirmed that arthropod communities associated with GM treatments were ecologically comparable to those of non-GM controls within each region and year (<i>p</i> > .05). Non-metric multidimensional scaling (NMDS) ordination revealed clear clustering by region and year, with substantial overlap among treatments. Permutational multivariate analysis of variance showed that year explained the largest proportion of the variation (<i>R²</i> = 0.640), whereas treatment effects were negligible (<i>R²</i> = 0.006). Overall, these results provide robust field-based evidence that glufosinate-tolerant and male-sterile GM zoysiagrass does not adversely affect non-target arthropod communities, supporting its environmental safety in perennial agroecosystems.</p>","PeriodicalId":54282,"journal":{"name":"Gm Crops & Food-Biotechnology in Agriculture and the Food Chain","volume":"17 1","pages":"2704431"},"PeriodicalIF":4.3,"publicationDate":"2026-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13418464/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148581200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guided by the Risk Information Seeking and Processing (RISP) model, this study examined factors influencing information seeking, information avoidance, and information processing related to CRISPR-edited pork products among U.S. consumers (<i>n</i> = 2,006). Results show higher information sufficiency thresholds were associated with greater information seeking and lower information avoidance. Information seeking was strongly and positively correlated with systematic processing. Relevant channel beliefs and perceived information gathering capacities were positively associated across communication channels, suggesting the need for integrated communication approaches. Relevant channel beliefs for news media and social media were positively associated with information seeking, while stronger relevant channel beliefs for Extension were associated with lower information seeking. Respondents with some college education reported higher information seeking than those with only a high school diploma or GED, while older adults and individuals with higher education levels reported lower information avoidance. Results also showed that respondents exhibited high intentions to seek information and low tendencies to avoid information, suggesting openness to learning about CRISPR-edited pork. Participants also reported engaging more in systematic processing than heuristic processing, indicating a preference for careful and analytical evaluation of information.

This study takes 25 Chinese youth aged 19-27 as its research participants, collects data through semi-structured in-depth interviews, and analyzes the process of attitude formation by applying grounded theory through open coding, axial coding, and selective coding. The findings show that young people usually take government announcements, expert interpretations, and mainstream media reports as their initial points of reference, while also conducting cross-source verification through social media, peer discussion, and personal experience, thereby displaying the coexistence of authoritative dependence and rational skepticism. On this basis, respondents did not generally develop attitudes of absolute support or outright rejection, but instead showed a tendency toward limited acceptance with conditional reservations. Further analysis indicates that accumulated socialization experiences and institutional trust give a certain degree of continuity to such judgments in subsequent encounters with information. On this basis, this article proposes an interpretive framework of authoritative dependence - rational skepticism - balance effect - trust inertia.

Here, we describe the role of a sugarcane gene, <i>ScTpx2</i>, which is induced by drought in sugarcane leaves under field conditions. When overexpressed in <i>Arabidopsis</i>, <i>ScTpx2</i> enhanced plant survival under extreme water deficit and improved performance under mild stress conditions, which better represent field scenarios.

Additionally, the vascular bundles and xylem areas were larger in <i>ScTpx2</i>OE compared to WT. These findings suggest that the <i>ScTpx2</i> protein influences the development of the vascular system, thereby improving water transport efficiency.
