Replacing inorganic trace elements with organic trace elements provides a promising solution to alleviate these problems. Therefore, this study aimed to assess the impact of replacing all inorganic trace elements (ITMs) in feed on the growth performance, meat quality, serum parameters, trace element metabolism, and gut microbiota of finishing pigs.

A CCA1-like MYB subfamily member CsMYB128 participates in chilling sensitivity and cold tolerance in tea plants (Camellia sinensis).

While flavonoid accumulation, light radiation, and cold stress are intrinsically connected in tea plants, yet the underlying mechanisms remain elusive. The circadian protein CCA1 and CCA1-like MYB transcription factors (TFs) play important roles in coordinating light and temperature signals in plant-environment interactions, their homologs in tea plants have not been addressed. Here we analyzed CsCCA1-like MYB subfamily in tea genome and found one member, a circadian gene CsMYB128 responding to cold stress.

Unraveling key ABA pathways, including OsWRKY71-OsABA8ox1 and OsbZIP73-OsNCED5, provides valuable insights for improving cold tolerance in rice breeding for cold-prone regions. Cold stress limits rice (Oryza sativa L.) production in cooler climates.

Mixed exposure to PFOA and PFOS induces oocyte apoptosis and subfertility in mice by activating the Hippo signaling pathway.

Per- and polyfluoroalkyl substances (PFAS) are synthetic perfluorinated compounds known for their persistence in the environment and reproduction toxicity. PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), have been identified in the follicular fluid of infertile women.

Similarity in the microbial community structure of tobacco from geographically similar regions.

To investigate the structural and functional similarities of microbial communities in burnt-sweetness alcoholized tobacco as a function of distance from the equator and their effects on tobacco quality, we sampled alcoholized tobacco from Chenzhou, Hunan Province, China and from Brazil and Zimbabwe, which are also burnt-sweetness-type tobacco producing regions, and performed high-throughput sequencing of tobacco bacterial and fungal communities along with an analysis of the main chemical constituents of the tobacco to analyze differences in the quality of the tobacco and similarities in the structure of the microbial communities. The total nitrogen, nicotine and starch contents of Chenzhou tobacco were greater than those of Brazilian and Zimbabwean tobacco, and the total sugar and reducing sugar contents of the Brazilian and Zimbabwean tobacco were greater than those of the Chenzhou tobacco (P < 0.05).

Cadmium exposure increases insecticide sensitivity of Sogatella furcifera (Horváth) by decrease the diversity of symbiotic bacteria.

Cadmium (Cd) is a prevalent environmental pollutant in agricultural ecosystems, particularly within paddy ecosystems, is readily absorbed by rice and enter herbivorous insects through the food chain, thereby influencing the implementation of integrated pest management strategies. However, the effect and mechanisms of Cd exposure on the sensitivity of pests in paddy to insecticides remain unclear. Therefore, this study investigated the effects of Cd exposure on the fitness, insecticide sensitivity and symbiotic bacteria of Sogatella furcifera (Horváth) (white-backed planthopper, WBPH).

, a perennial herb belonging to the Zingiberaceae family, has a long history of traditional medicinal use. The present study evaluated the efficacy of different concentrations of essential oil (AEO) on the growth performance, serum antioxidation capacities, immune function, apparent digestibility of nutrients, and gut microbiota in fattening pigs. A total of 120 pigs were divided into five treatments, with six replicates each and four pigs per replicate.

It is time to reevaluate the lard in glucose homeostasis and diabetes pathogenesis.

Most modern dietary guidelines recommend limiting lard and animal fats due to their potential link to metabolic diseases. Nevertheless, emerging evidence suggests that lard may not significantly contribute to diabetes and that moderate lard intake could even benefit lipid metabolism. This commentary suggests a reevaluation of lard’s classification as a “bad actor” in the context of diabetes, urging colleagues to give greater consideration to and empirically validate this intriguing hypothesis.

Design of highly leaf-adhesive and anti-UV herbicide nanoformulation for enhanced herbicidal activity.

Introduction: Conventional pesticide formulations have been widely used to boost agricultural productivity, but their weak foliar adhesion and instability under UV light during spraying lead to low utilization rates and potential environmental and health hazards. To counter these challenges, the development of nanoformulations represents a pivotal strategy. These advanced formulations are designed to enhance the efficacy of active ingredients (AIs) and reduce ecological impacts, thereby addressing the need for sustainable agricultural development.
