Other claims from this paper (10)
- Observation SiMAPKKK17 expression was comparatively higher in vegetative tissues, including roots, stems and leaves.
- Observation SiMAPKKK17 was localized to both the plasma membrane and the nucleus.
- Intervention effect Under drought stress, foxtail millet lines overexpressing SiMAPKKK17 showed enhanced drought tolerance compared with wild-type plants.
- Intervention effect Under drought, overexpression lines had greener and more upright upper leaves than wild-type plants.
- Intervention effect Under drought, overexpression lines had higher aboveground fresh weight, greater plant height and larger leaf area than wild-type plants.
- Observation Transcriptome analysis under drought stress identified 3919 upregulated genes in OE4 compared with WT.
- Observation Transcriptome analysis under drought stress identified 2965 downregulated genes in OE4 compared with WT.
- Observation The differentially expressed genes were mainly enriched in chloroplast-related cellular components and in processes and pathways related to amide metabolism, ion transport, carbon metabolism, photosynthesis, carbon fixation, purine metabolism and amino acid biosynthesis.
- Mechanism SiMAPKKK17 acts as a positive regulator of drought tolerance in foxtail millet, potentially through modulation of photosynthesis- and metabolism-related pathways.
- Recommendation SiMAPKKK17 is a promising candidate gene for developing drought-resistant foxtail millet cultivars.
