The sugarcane ScMYB3R1-ScPYL61-ScPP2C57 module confers drought tolerance via ABA signaling.

Drought stress constitutes a significant challenge for plant growth, particularly impacting sugarcane yield and quality. MYB transcription factors play a pivotal role in regulating drought tolerance in plants, yet investigations into the 3R-MYB subfamily remain limited. Here, we identified 35 sugarcane 3R-MYB genes, in which ScMYB3R1 significantly responds to PEG and ABA treatments.

Whole genome sequencing revealed genetic structure, domestication, and selection of Chinese indigenous ducks.

The genetic architecture and domestication history of Chinese indigenous ducks, particularly those with distinct traits like the Longsheng duck (LSD), are not well characterized. This study used whole-genome resequencing data from 540 ducks across 30 populations to explore the genetic diversity and structure of these ducks. Our findings suggest extensive interspecific hybridization between mallard and spot-billed duck.

Deciphering the Genetic Landscape: Insights Into the Genomic Signatures of Changle Goose.

The Changle goose (CLG), a Chinese indigenous breed, is celebrated for its adaptability, rapid growth, and premium meat quality. Despite its agricultural value, the exploration of its genomic attributes has been scant. Our study entailed whole-genome resequencing of 303 geese across CLG and five other Chinese breeds, revealing distinct genetic diversity metrics.

Genomic characteristics and selection signals of Zhongshan ducks.

The Zhongshan duck (ZSP) is a duck breed indigenous to China and is known for its moderate body size, strong disease resistance, tender meat, and little subcutaneous fat. However, the genomic basis of such excellent breeding characteristics remains poorly understood. Therefore, we generated whole-genomes of 58 ZSPs and 180 other indigenous Chinese ducks (60 Jinding ducks, 60 Shan Partridge ducks, and 60 Liancheng white ducks) and identified 10 560 032 single nucleotide polymorphisms and 1 334 893 structural variants.

Microbial diversity and community composition of fecal microbiota in dual-purpose and egg type ducks.

Introduction: Ducks are important agricultural animals, which can be divided into egg and dual-purpose type ducks according to economic use. The gut microbiota of ducks plays an important role in their metabolism, immune regulation, and health maintenance.

Methods: Here, we use 16S rDNA V4 hypervariable amplicon sequencing to investigate the compositions and community structures of fecal microbiota between egg (five breeds, 96 individuals) and dual-purpose type ducks (four breeds, 73 individuals) that were reared under the same conditions.

Genomic signatures and evolutionary history of the endangered blue-crowned laughingthrush and other Garrulax species.

Background: The blue-crowned laughingthrush (Garrulax courtoisi) is a critically endangered songbird endemic to Wuyuan, China, with population of ~323 individuals. It has attracted widespread attention, but the lack of a published genome has limited research and species protection.

Results: We report two laughingthrush genome assemblies and reveal the taxonomic status of laughingthrush species among 25 common avian species according to the comparative genomic analysis.

Synthesis of iridium-based nanocomposite with catalase activity for cancer phototherapy.

The combination of photothermal therapy (PTT) and photodynamic therapy (PDT) has attracted attention due to its enhanced tumor therapy effect. This study proposes a novel nanoenzyme-based theranostic nanoplatform, IrO@MSN@PDA-BSA(Ce6), for the combined PTT and PDT of tumors. IrO was prepared by a simple hydrolysis method and coated with a thin layer of mesoporous silica (MSN) to facilitate the physical adsorption of Chlorin e6 (Ce6).

Preparation of Bi-based hydrogel for multi-modal tumor therapy.

Radiotherapy (RT) is becoming a pervasive therapeutic pattern in clinical cancer therapy. However, the hypoxic microenvironment of tumors has a strong resistance to radiotherapy and could lead to a potential recurrence and metastasis after the treatment. Therefore, the use of synergistic strategies for improving and supplementing the RT efficiency is important.

Magnetic Silica Nanosystems With NIR-Responsive and Redox Reaction Capacity for Drug Delivery and Tumor Therapy.

In recent years, more and more researches have focused on tumor photothermal therapy and chemodynamic therapy. In this study, we prepared a multifunctional nanomaterial with potential applications in the above area. The FeO nanoparticles were synthesized with suitable size and uniformity and then coated with mesoporous silica and polydopamine.

Integration of FeO with BiS for Multi-Modality Tumor Theranostics.

The combination of reactive oxygen species (ROS)-induced chemodynamic therapy (CDT) and photothermal therapy (PTT) holds a promising application prospect for their superb anticancer efficiency. Herein, we created a novel FeO@polydopamine (PDA)@bovine serum albumin (BSA)-BiS composite as a theranostic agent, by chemically linking the FeO@PDA with BSA-BiS via the amidation between the carboxyl groups of BSA and the amino groups of PDA. In this formulation, the FeO NPs could not only work as a mimetic peroxidase to trigger Fenton reactions of the innate HO in the tumor and generate highly cytotoxic hydroxyl radicals (•OH) to induce tumor apoptosis but also serve as the magnetic resonance imaging (MRI) contrast agent to afford the precise cancer diagnosis.
