Stress-associated proteins (SAPs) are zinc finger proteins involved in the regulation of various stresses in a variety of plant species. A total of nine genes were identified in . Phylogenetic and synteny analyses were performed to analyze the homology and evolutionary relationship of genes. The functions of genes were assessed by further analyses, including -regulatory elements, gene duplication, gene ontology, gene structure, subcellular localization, and motif pattern. This study found that genes were unevenly distributed on chromosomes 2, 3, 6, and 7. Phylogenetic analysis of genes with and suggested that six subgroups have a similar pattern of AN1 and A20 domains in each subgroup. genes lacked duplicated blocks. The majority of genes were localized in the nucleus region. Three hormonal and five stress -regulatory elements were found in the upstream promoter region of the gene family. RNA-seq analysis revealed differential gene expression of genes at days 12, 17, 22, 27, 32, and 37 of fruitlet development after flowering. This study identifies the SAP genes in and also provides insights into the expression of genes in abnormal fruitlets with diapause atrophic growth at various developmental stages.

Overexpression of AtbZIP69 in transgenic wheat confers tolerance to nitrogen and drought stress.
Planta

State Key Laboratory of Crop Gene Resources and Breeding, Institute of Crop Sciences, Chinese Academy of Agricultural Sciences (CAAS), Beijing, 100081, China.
AtbZIP69 overexpression in wheat significantly enhanced drought and low nitrogen tolerance by modulating ABA synthesis, antioxidant activity, nitrogen allocation, and transporter gene expression, boosting yield. In this study, we generated wheat plants with improved low nitrogen (LN) and drought tolerance by introducing AtbZIP69, a gene encoding a basic leucine zipper domain transcription factor, into the wheat cultivar Shi 4056. AtbZIP69 localized to the nucleus and activated transcription.

Background/purpose: Although metabolic dysfunction-associated steatotic liver disease (MASLD) has been proposed to replace the diagnosis of non-alcoholic fatty liver disease (NAFLD) with new diagnostic criteria since 2023, the genetic predisposition of MASLD remains to be explored.
Methods: Participants with data of genome-wide association studies (GWAS) in the Taiwan Biobank database were collected. Patients with missing data, positive for HBsAg, anti-HCV, and alcohol drinking history were excluded.
Frequency of somatic and germline variants of predisposition genes in young Chinese women with breast cancer.

Department of Breast Surgery, Fujian Medical University Union Hospital, Fuzhou, 350001, Fujian , China.
Purpose: Age stratification influences the clinicopathological features and survival outcomes of breast cancer. We aimed to understand the effect of age on gene variants in young Chinese women with breast cancer compared with those from The Cancer Genome Atlas (TCGA).
Methods: Enrolled patients ≤ 40 years old (N = 370) underwent germline or somatic genetic testing using a 32-gene hereditary cancer panel at Fujian Union Hospital.
Biologically-targeted discovery-replication scan identifies G×G interaction in relation to risk of Barrett's esophagus and esophageal adenocarcinoma.

Inherited genetics represents an important contributor to risk of esophageal adenocarcinoma (EAC), and its precursor Barrett's esophagus (BE). Genome-wide association studies have identified ∼30 susceptibility variants for BE/EAC, yet genetic interactions remain unexamined. To address challenges in large-scale G×G scans, we combined knowledge-guided filtering and machine learning approaches, focusing on genes with (A) known/plausible links to BE/EAC pathogenesis (n=493) or (B) prior evidence of biological interactions (n=4,196).

Gastric cancer (GC), one of the most common and heterogeneous malignancies, is the second leading cause of cancer death worldwide and is closely related to dietary habits. Fatty acid is one of the main nutrients of human beings, which is closely related to diabetes, hypertension and other diseases. However, the correlation between fatty acid metabolism and the development and progression of GC remains largely unknown.
