Azerbaijan is major producer of fruit crops, such as pome and stone fruits, in the Caspian Sea and Caucasus Mountains areas (FAO Stat, 2022). No information is available on the occurrence of apple chlorotic leaf spot virus (ACLSV, genus Trichovirus, family Betaflexiviridae) in the country. Therefore, the main fruit tree production areas in Azerbaijan were surveyed for ACLSV during the 2017-2019 growing seasons by DAS-ELISA using ACLSV reagents (Neogen - Scotland, UK) (Clark and Adams 1977).

Natural variation of CTB5 confers cold adaptation in plateau japonica rice.

Nat Commun

January 2025

Frontiers Science Center for Molecular Design Breeding, Beijing Key Laboratory of Crop Genetic Improvement, College of Agronomy and Biotechnology, China Agricultural University, Beijing, China.

During cold acclimation in high-latitude and high-altitude regions, japonica rice develops enhanced cold tolerance, but the underlying genetic basis remains unclear. Here, we identify CTB5, a homeodomain-leucine zipper (HD-Zip) transcription factor that confers cold tolerance at the booting stage in japonica rice. Four natural variations in the promoter and coding regions enhance cold response and transcriptional regulatory activity, enabling the favorable CTB5 allele to improve cold tolerance.

January 2025

School of Advanced Agriculture Sciences and School of Life Sciences, State Key Laboratory of Protein and Plant Gene Research, Peking University, Beijing, 100871, China.

In plants, microRNAs (miRNAs) participate in complex gene regulatory networks together with the transcription factors (TFs) in response to biotic and abiotic stresses. To date, analyses of miRNAs-induced transcriptome remodeling are at the whole plant or tissue levels. Here, Arabidopsis's ABA-induced single-cell RNA-seq (scRNA-seq) is performed at different stages of time points-early, middle, and late.

With the growing attention on green starch modification technologies, this study investigates the regulatory effects of alternating magnetic field treatment on the fine structure and functional properties of pregelatinized cassava starch at different treatment times (10 min, 30 min, 50 min).The results demonstrate that magnetic field treatment not only increased starch cracks and compactness but also promoted molecular chain breakage and reorganization, hydrogen bond formation, and starch recrystallization, thereby enhancing molecular order. Moreover, the treated starch exhibited improved solubility and swelling power, alongside a positive impact on the content of slowly digestible starch.

DUO1 Activated Zinc Finger (AtDAZ) protein role in the generative cell body morphogenesis.

Plant Mol Biol

January 2025

National Key Laboratory for Tropical Crop Breeding, Tropical Crop Genetic Resources Institute, Chinese Academy of Tropical Agricultural Sciences, Sanya, Haikou, 572024/571101, Hainan, China.

Arabidopsis MYB transcription factor, AtDUO1 regulates generative cell body (GC) morphogenesis from round to semi and fully elongated forms before pollen mitosis-II (PM II). It was hypothesised that DUO1 might regulate morphogenesis through any of its direct target genes or components of the DUO1-DAZ1 network. The developmental analysis of plants harbouring T-DNA insertions in some DUO1 target genes using light and fluorescence microscopy revealed abnormal GC morphogenesis only in daz1 and daz2, but gcs1, trm16, mapkkk10, mapkkk20, tet11, and tip1 all undergo normal elongation indicating that these target genes have no important roles in morphogenesis or may be redundant.

Drugs

December 2024

Department of Pharmacy and Institutes for Systems Genetics, Frontiers Science Center for Disease-related Molecular Network, West China Hospital, Sichuan University, Chengdu, 610212, China.

Article Synopsis
  • The study addresses the challenges in evaluating large language models (LLMs) in pharmacology due to the absence of a comprehensive test set.
  • It creates a specialized pharmacology test set with tasks like drug information retrieval and trend summarization, comparing the performance of GPT-3.5 and GPT-4.
  • The findings show that while these models excel in understanding and summarizing pharmacological information, they struggle with specific tasks like drug identification and interaction retrieval, suggesting that enhancing them with retrieval-augmented generation or specialized knowledge bases could improve their efficacy in pharmacology.
