The Role of Phosphorus Fertilization in Antioxidant Responses of Drought-Stressed Common Beech and Sessile Oak Provenances

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(7), С. 3053 - 3053

During drought, a major abiotic stressor for European forests, excessive reactive oxygen species (ROS) are produced, causing oxidative damage that affects structural and metabolic tree functions. This research examines the effects of phosphorus (P) fertilization, provenance on photosynthetic pigments, malondialdehyde (MDA) concentrations, antioxidant enzyme activities in common beech (Fagus sylvatica L.) sessile oak (Quercus petraea (Matt.) Liebl.) saplings from two provenances. In garden experiment, four treatments were applied: regular watering with (+PW) without P fertilization (-PW), drought (+PD) (-PD) fertilization. Results showed increased both MDA concentrations activity, particularly superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate (APX), which responsible ROS scavenging. Additionally, chlorophyll + b lower drought-exposed plants. Phosphorus minimally affected levels but enhanced responses, APX CAT during drought. Provenance differences notable, drier showing better adaptation, reflected higher activities. study underscores importance defenses coping stress, shaping species' adaptive capacity.

Genome-Wide Identification of GATA Transcription Factors in Acorus and Expression Patterns Under Abiotic Stress

Horticulturae, Год журнала: 2025, Номер 11(4), С. 410 - 410

Опубликована: Апрель 11, 2025

The GATA transcription factors are a class of DNA-binding proteins that control the expression target genes by binding to promoter regions DNA, thereby affecting growth and development plants. In recent years, have been discovered functionally characterized in many plant species. However, there is limited annotation information for genus Acorus. This study identified 38 20 Acorus calamus A. gramineus, respectively. Based on phylogenetic tree, they were classified into four subfamilies (I, II, III, IV). At same time, an analysis domain motifs revealed domains relatively conserved across all subfamilies. A multiple sequence alignment showed almost highly at LCNACG site. An cis-elements, collinearity, protein–protein interaction networks provided insights response mechanisms under biotic stress. Additionally, we found significant changes gramineus drought salt These results provide useful future functional analyses contribute better understanding stress molecular breeding directions

Identification of critical transition signal (CTS) to characterize regulated stochasticity during ABA-induced growth-to-defense transition

BMC Plant Biology, Год журнала: 2025, Номер 25(1)

Опубликована: Апрель 24, 2025

Abscisic acid (ABA) plays a central role in regulating plant responses to abiotic stress. It orchestrates complex regulatory network that facilitates the transition from growth defense. Understanding molecular mechanisms underlying this ABA-induced defense is essential for elucidating adaptive strategies under environmental stress conditions. In study, we used refined dynamic biomarker (DNB) approach quantitatively identify critical signal (CTS) and characterize regulated stochasticity during Arabidopsis thaliana. By integrating high-resolution time-series RNA-seq data with analysis, identified set of DNB genes serve as key regulators transition. The phase was precisely at ninth time point (6 h after treatment), which marks crucial switch growth-dominated -oriented state. Gene Ontology (GO) enrichment analysis revealed significant overrepresentation defense-related biological processes, while STRING strong functional interactions between differentially expressed (DEGs) highlighted hubs. particular, hub such PIF4, TPS8, NIA1, HSP90-5 were potential master ABA-mediated activation, highlighting their importance adaptation. network-driven transcriptomic study provides new insights into basis transitions identification CTS perspective on conceptual framework improving crop resistance. addition, establishment comprehensive database ABA-responsive represents valuable resource future research adaptation resilience.

Integrated Analysis of Long Non-Coding RNAs and mRNAs Reveals Key Trans-Target Genes Associated with Heat Stress Response in Rhododendron delavayi

Life, Год журнала: 2025, Номер 15(5), С. 697 - 697

Опубликована: Апрель 25, 2025

Long non-coding RNAs (lncRNAs) have been defined as transcripts exceeding 200 nucleotides, which play essential roles during transcriptional and post-transcriptional regulation in multiple biological processes. Understanding R. delavayi lncRNAs is of great significance it profoundly influenced by heat stress. In this research, a total 1145 differentially expressed (DE-lncRNAs) 9447 genes (DEGs) (log2|FC| > 1, p < 0.05) were characterized between heat-stress-treated groups control groups. Further analysis showed that 229 DE-lncRNAs (144 upregulated 85 downregulated) commonly distributed two comparisons (CK_vs._H3 CK_vs._H6). We further investigated the cis- trans-acting DE-lncRNAs, found 142 corresponded to 1565 cis-acting DEGs, 143 3417 DEGs. KEGG enrichment these target revealed DEGs DE-lncRNA primarily enriched five twelve pathways, respectively.
