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.
Gramene and SorghumBase Teams at PAG33 in San Diego, California, January 9-14, 2024

Integrated Physiological and Molecular Mechanisms Underlying Sorghum Responses to Alkali Stress
Liu et al. found that though alkali stress disrupts growth, osmotic balance, and cellular stability in sorghum, the tolerant genotype Z14 counters these effects through stronger antioxidant defenses, enhanced osmotic regulation and rapid activation of stress-responsive genes and signaling pathways.
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.
