Sorghum seed coat color correlates with the accumulation of phenolic and volatile compounds, and key regulatory genes including ABCB28, PTCD1, and ANK have been identified as central to their biosynthesis and transport.
SbC1 as a Key Regulator of Anthocyanin Biosynthesis and Stress Tolerance in Sorghum Coleoptiles
Ding et al. identified SbC1, an R2R3-MYB transcription factor, as a key regulator of anthocyanin biosynthesis in sorghum coleoptiles, highlighting its role in pigmentation, stress tolerance, and potential applications in crop improvement.
Vulnerability of Cereal Crop Landraces Under Post-Catastrophic Climate Scenarios
Though the diversity of native crop varieties (landraces) may be useful for increasing food security under novel environmental conditions, in the scenario of a soot-producing catastrophe, local genetic diversity is insufficient to ensure agricultural resilience without long-distance genotype substitutions or crop shifts.
ABA Seed Priming Enhances Drought Tolerance in Sorghum Through Hormonal Regulation and Stress-Responsive Transcriptional Networks
ABA seed priming enhances drought tolerance in sorghum by modulating hormonal pathways and activating key transcription factors like SbNAC21-1, enabling improved stress resilience without compromising growth.
G14: A Stable, High-Yielding, and Nutrient-Rich Red Sorghum Genotype for Diverse Agro-Climatic Zones of Tamil Nadu
G14 emerged as the most stable and high-yielding red sorghum genotype with superior nutritional traits, making it ideal for cultivation across diverse environments in Tamil Nadu.
Genetic Dissection of Seed Dormancy in Sorghum Reveals qDOR-9 as a Key Locus Linked to ABA Sensitivity, Flowering Time, and Pre-Harvest Sprouting Susceptibility
RodrÃguez et al. identified and validated the qDOR-9 locus in sorghum as a key regulator of seed dormancy, linking it to ABA sensitivity and flowering time, and highlighting its unintended association with PHS susceptibility due to historical breeding for dwarfism.
Hormonal Regulation of Sugar Transport Drives Salt Tolerance Through Strategic Resource Allocation in Sorghum
Salt tolerance in sorghum is closely linked to hormone-regulated sugar transporter expression that controls resource allocation between roots, stems, and grains during development, enabling stress-resilient genotypes like Della to delay sodium translocation and sustain metabolic balance.
Identification of a BPM Domain-Containing Gene Regulating Panicle Exsertion in Sorghum for Mechanized Harvesting Adaptation
Ao et al. identified a BPM domain-containing gene on chromosome 10 as a key regulator of panicle exsertion in sorghum, linking impaired BR signaling and reduced parenchyma cell elongation to a sheathed panicle phenotype, with implications for breeding varieties suited for mechanized harvesting.
H3K36me3-Mediated Chromatin Regulation Orchestrates Plant Development and Antagonizes Repressive Epigenetic Marks
H3K36me3 plays a crucial role in plant development by activating gene expression and antagonizing repressive chromatin marks like H3K27me3 and H2A.Z, thereby shaping developmental and tissue-specific transcriptional programs.
Uncovering Genetic Architecture of Agronomic Traits in Ethiopian Sorghum Landraces Through Multi-Locus GWAS for Genomics-Assisted Breeding
Researchers utilized multi-locus GWAS to uncover key QTNs and candidate genes associated with agronomic and yield-related traits in Ethiopian sorghum landraces, providing valuable insights for genomics-assisted breeding of resilient, high-yielding varieties.
