Exogenous spermidine and the CaSPDS gene regulate salt tolerance by maintaining ROS homeostasis and photosynthetic function in pepper seedlings

Zijian Xu, Xianqi Zhao, Yan Zhang, Su Wang et autres

Salt stress severely restricts pepper ( Capsicum annuum L.) growth and productivity by disrupting osmotic balance, damaging the photosynthetic system, and inducing excessive reactive oxygen species (ROS) accumulation. Spermidine (Spd), an important polyamine, plays critical roles in plant stress adaptation; however, the …

Lowering the δ-to-α Phase-Transition Barrier via a Transient Vapor Mediator in Perovskite Formation

Weiwei Chen, Jinshuai Zhang, Zehuan Jia, Zijian Xu et autres

Hybrid sequential deposition (HSD) remains a practical pathway for the scalable fabrication of perovskite photovoltaics, though it is frequently constrained by the formation of dense evaporated precursor frameworks and the associated kinetic limitations of the subsequent solid interdiffusion. These constraints often manifest …

ORCA: ORgan-Centroid Aggregation for Training-Free 3D CT Visual Token Compression

Renjie Liang, Zijian Xu, Jinqian Pan, Chengkun Sun et autres

A 3D CT scan entering a vision-language model produces a long sequence of visual tokens, often thousands to tens of thousands per volume, and this sequence must be compressed before a language model can consume it. Token compression is well studied in …

When Do Cheap Probes Predict Expensive Training? Probing 3D-CT Encoders for Text Generation

Renjie Liang, Zijian Xu

Building a 3D CT vision language model begins with a choice of which image encoder to build on. Today that choice is made by fine-tuning every candidate through the full language model and comparing downstream scores, an enormously expensive search. A cheap …

Unveiling the potential regulatory functions of long non-coding RNAs in potato tuberization through integrated analysis of transcriptomics and phytohormone profiles

Yunling Ye, Yang Yang, Ang Li, Ling Xiang et autres

BACKGROUND: Long non-coding RNAs (lncRNAs) are pivotal in plant development, including organ morphogenesis. However, currently, the biological significance of potato lncRNAs is still not fully known. This study delved into the cytological, transcriptomic, and phytohormonal dynamics that lie beneath potato tuberization. Special …

Multi-Scale Gaussian-Language Map for Zero-shot Embodied Navigation and Reasoning

Sixian Zhang, Yiyao Wang, Xinhang Song, Keming Zhang et autres

Understanding the geometric and semantic structure of environments is essential for embodied navigation and reasoning. Existing semantic mapping methods trade off between explicit geometry and multi-scale semantics, and lack a native interface for large models, thus requiring additional training of feature projection …

Synergistic A-Site Codoping Enables Lattice Stabilization and Strain Balance in Wide-Bandgap Perovskites

Zijian Xu, W. X. Peng, Kai Zhang, Weiwei Chen et autres

Wide-bandgap (WBG, ∼1.75–1.80 eV) perovskites are essential for tandem solar cells, but suffer from rapid crystallization, defects, and instability. Single-cation strategies face intrinsic trade-offs: methylammonium (MA) accelerates lattice formation but volatilizes under thermal stress, whereas guanidinium (GA) strengthens lattice interactions yet introduces …

Itaconate reduces viral endocytosis by targeting Cys128 of the adaptor-related protein complex 1 gamma 1 subunit in the host, providing a novel target for antiviral drug development

Xinqi Deng, Heng Chen, Zhi-Xing Huang, Rongxing He et autres

Traditional antiviral strategies primarily rely on vaccines and virus protein-targeting drugs, which adopt a virus-targeting approach. However, the rapid mutation of viruses often leads to vaccine failure and drug resistance, highlighting the limitations of these conventional methods. Consequently, the development of novel …

The potential role of short internodes/stylish (SHI/STY) and SHI related sequence (SRS) in potato tuberization

Yang Yang, Yunling Ye, Shareef Gul, Ximei Liao et autres

BACKGROUND SRS: (Short Internodes/Stylish/SHI-Related Sequence) genes play a crucial role in plant developments, encompassing organ morphogenesis. However, at present, the biological significance of potato StSRS genes remains unknown. This study comprehensively identified and analysed the potential functions of StSRS genes in potato …

TeloComp: An efficient toolkit for accurate assembly of the telomeres in T2T genomes

Jie Wu, Zijian Xu, Wei Mo, Shuai Yuan et autres

The completeness and accuracy of genome assemblies are crucial for ensuring the reliability of downstream analyses, including functional and evolutionary studies. With the advent of third-generation sequencing, the assembly of telomere-to-telomere (T2T) genomes has become possible. Telomeres are regions of tandemly repeated …

Selenium-enriched Lactobacillus coryniformis H8 alleviates LPS-induced jejunal injury in chicks by modulating antioxidant activity, inflammation, selenoprotein genes, and gut microbiota

Zijian Xu, Dan Xiao, Ke Chen, Jingli Han et autres

Intestinal inflammation in chicks remains a prevalent health concern, highlighting the importance of developing effective alternatives to conventional antibiotics. This study aimed to investigate the effect of selenium-enriched Lactobacillus coryniformis H8 (Se-H8) in alleviating lipopolysaccharides (LPS)-induced intestinal inflammation in chicks and the …
