Special Issue Information

Dear Colleagues, 

Plants respond to environmental stresses through complex and highly coordinated molecular regulatory networks. These networks accommodate signal perception, transduction, and gene expression, enabling plants to adapt to diverse abiotic stress conditions. By deciphering these regulatory mechanisms, researchers can identify key stress-responsive genes, offering valuable targets for crop improvement.

Recent advances in multi-omics integration technologies—including genomics, transcriptomics, proteomics, metabolomics, epigenomics, and phenomics—have provided unprecedented resolution in dissecting plant stress responses. Integrative analyses across these data layers reveal the intricate connections between the gene regulatory circuits, signaling pathways, and metabolic processes involved in stress adaptation.

This Special Issue aims to highlight the latest breakthroughs in multi-omics integration for unraveling plant molecular regulatory networks under stress. We especially welcome studies employing innovative technologies such as deep learning, artificial intelligence, single-cell RNA sequencing, spatial transcriptomics/genomics, or advanced bioinformatics pipelines to identify key regulatory hubs/genes and predict stress-responsive elements.

We invite original research and comprehensive reviews that provide novel insights into plant–environment interactions enabled by multi-omics integration and support the advancement of precision breeding approaches.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.

Nowadays, with the accumulation of large amounts of stress-response transcriptomic data in plants, it is possible to clarify the key genes and transcription factors (TFs) involved in these processes. Here, we present the comprehensive transcriptomic meta-analysis of the high light (HL) response in photosynthetic tissues of Arabidopsis thaliana (L.) Heynh., offering new insights into adaptation mechanisms of plants to excessive light and involved gene regulatory networks. We analyzed 21 experiments covering 58 HL conditions in total, yielding 218,000 instances of differentially expressed genes (DEGs) corresponding to 19,000 unique genes. Based on these data, we developed the publicly accessible AraLightDEGs resource, which offers multiple search filters for experimental conditions and gene characteristics, and we conducted a detailed meta-analysis using our R pipeline, AraLightMeta. Our meta-analysis highlighted distinct transcriptional programs between short- and long-term HL responses in leaves, revealing novel regulatory interactions and refining the understanding of key DEGs. In particular, long-term HL adaptation involves key TFs such as CRF3 and PTF1 regulating antioxidant and jasmonate signaling; ATWHY2, WHY3, and emb2746 coordinating chloroplast and mitochondrial gene expression; AT2G28450 governing ribosome biogenesis; and AT4G12750 controlling methyltransferase activity. We integrated these findings into a conceptual scheme illustrating transcriptional regulation and signaling processes in leaf cells responding to long-term HL stress. Full article
