Article Abstract

Plant basic helix-loop-helix (bHLH) transcription factors are involved in the regulation of various biological processes in plant growth, development, and stress response. However, members of this important transcription factor family have not been systematically identified and analyzed in pepper ( L.). In this study, we identified 122 genes in the pepper genome and renamed them based on their chromosomal locations. were divided into 21 subfamilies according to their phylogenetic relationships, and genes from the same subfamily had similar motif compositions and gene structures. Sixteen pairs of tandem and segmental duplicated genes were detected in the CabHLH family. -elements identification and expression analysis of the revealed that they may be involved in plant development and stress responses. This study is the first comprehensive analysis of the genes and will serve as a reference for further characterization of their molecular functions.

Climatic challenges increasingly threaten global food security, necessitating crops with enhanced multi-stress resilience. Through systematic transcriptomic analysis of 100 wheat genotypes under heat, drought, cold, and salt stress, we identified 3237 differentially expressed genes (DEGs) enriched in key stress-response pathways. Core transcription factors (, , ) and two functional modules governing abiotic tolerance were characterized.

The purpose of this study was to investigate how Sphingosine-1-phosphate (S1P) signaling regulates glial phenotype, neuroprotection, and reprogramming of Müller glia (MG) into neurogenic MG-derived progenitor cells (MGPCs) in the adult male and female mouse retina. We found that S1P-related genes were dynamically regulated following retinal damage. (S1P receptor 1) and (sphingosine kinase 1) are expressed at low levels by resting MG and are rapidly upregulated following acute damage.

Catalpol, one of the major bioactive components in the traditional Chinese medicinal herb Rehmannia glutinosa, exhibits multiple pharmacological activities such as hypoglycemic and neuroprotective effects. Consequently, mechanistic elucidation of catalpol biosynthesis regulation in R. glutinosa is critically important.

Background: The most common endocrine cancer, thyroid carcinoma (TC), has a dismal prognosis when it reaches an advanced stage. Integrin α-2 () has been implicated in cancer progression, influencing both DNA damage and repair mechanisms. However, it is unknown how ITGA2 influences these processes in TC.
