Mining valuable genes is helpful to breed high-quality Salvia miltiorrhiza exhibiting efficient nitrogen fertilizer utilization efficiency. In the present study, transcriptome sequencing was introduced select candidate transcription factors (TFs) involved in tanshinones' (TAs) and phenolic acids' (PHAs) biosynthesis as well low (LN) stress. totally, 97.71 Gb clean data obtained from fifteen samples 30,975 unigenes were assembled. Among of them, 27,843 successfully annotated. Overall, 8663 differential expression (DEGs) identified, among which 5034 up-regulated, 3629 down-regulated. By enrichment DEGs together with gene co-expression network construction, 10 TFs including HSFB2b, LBD12, ERF1A, ERF98, LBD25, HSF24, RAM1, HSFA4B, TCP8, WRKY24 finally retrieved, are predicted participate modulating TA PHA under LN Quantitative real-time polymerase chain reaction (qRT-PCR) detection further detect profile These findings offer a resource for in-depth study TAs 'and PHAs' stress S. miltiorrhiza.

Discovery of SOD5 as a novel regulator of nitrogen‐use efficiency and grain yield via altering auxin level

Auxin has emerged as a crucial regulator of plant nitrogen (N)-use efficiency (NUE) through indirect effects on growth and development direct regulation N metabolism-related genes. We previously reported DULL NITROGEN RESPONSE1 (DNR1) an amino transferase that inhibits auxin accumulation negatively regulates rice (Oryza sativa) NUE grain yield. However, the identities molecular regulators acting upstream DNR1 await exploration. Our current work identifies SUPPRESSOR OF ON CHROMOSOME 5 (SOD5) from suppressor mutant. SOD5 encodes v-myb avian myeloblastosis viral oncogene homolog (MYB) transcription factor directly binds to promoter, activating its expression further repressing accumulation. Knocking out significantly increases yield, especially under low conditions. Therefore, targeting offers promising strategy for enhancing crop performance, supporting crops better suited sustainable agriculture.

The crosstalk between nitrate signaling and other signaling molecules in Arabidopsis thaliana

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Март 10, 2025

Nitrate signaling coordinates the expression of a broad range genes involved in nitrate uptake, transport, and assimilation, playing crucial role plant growth development. Notably, interacts extensively with various messenger molecules, including phytohormones, calcium ions (Ca 2+ ), reactive oxygen species (ROS), peptides, sucrose. This crosstalk amplifies optimizes nutrient coordinating developmental processes enhancing stress tolerance. Understanding interactions between these molecules offers valuable insights into improving crop use efficiency (NUE), resilience, agricultural sustainability. Using Arabidopsis thaliana as model, this review consolidates current knowledge on its interplay other pathways that regulate development adaptation. Finally, highlights potential genetic strategies for NUE, contributing to more sustainable practices.
