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.
Enhancing Sorghum’s Iron Deficiency Tolerance Through Genetic Engineering
Genetic engineering of sorghum with Fe deficiency-tolerant genes enhances iron uptake, phytosiderophore secretion, and stress resilience, improving growth in alkaline soils.
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.
Domestication-Driven Drought Resistance in Sorghum: The Role of Plant Architecture and Water-Conserving Traits
Domestication of Sorghum bicolor has led to drought-resistant traits, where a shorter stature and specific physiological mechanisms help conserve water and maintain grain yield under stress.
Enhancing Striga Resistance in Sorghum Through Molecular Marker-Assisted Breeding of LGS1 Mutations
Striga resistance in sorghum is achieved through molecular marker-assisted breeding targeting mutations at the LGS1 gene. These lgs1 mutants exude fewer Striga-stimulatory strigolactones, providing a sustainable solution for combating this parasitic weed.
m6A RNA Modifications Regulate Salt Tolerance in Sorghum through Transcript Stability and Stress Response Pathways
This study reveals that increasing m6A RNA modifications through SbMTA overexpression enhances salt tolerance in sorghum by stabilizing stress-responsive transcripts, whereas reducing m6A levels with SbALKBH10B overexpression diminishes this resilience.
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.
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.
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.
DG1-Mediated Floret Fertility Enhances Grain Yield and Breeding Potential in Sorghum
The DG1 gene in sorghum enhances lower floret fertility through epigenetic regulation, enabling double-grain spikelets that increase yield and hold promise for both crop improvement and liquor production.
