Sorghum polyamine oxidase genes exhibit distinct structural, evolutionary, and regulatory specializations that shape tissue- and genotype-specific stress responses, with SbPAO5 and SbPAO6 emerging as key contributors to drought tolerance and promising targets for crop improvement.
Linalool-Mediated Defense Mechanisms Underpin Sorghum Resistance to Anthracnose
Linalool enhances sorghum resistance to Colletotrichum sublineola-induced anthracnose by activating salicylic acid–mediated defense signaling and directly inhibiting fungal growth through membrane disruption and oxidative stress.
Dissecting the Genetic Basis of Root Traits in Sorghum Using Genome-Wide Association Studies
A genome-wide association study in sorghum identified 189 QTNs underlying root system architecture, highlighting a complex polygenic basis with candidate genes linked to hormone signaling, flavonoid biosynthesis, and stress adaptation.
Subfunctionalization of MBW Complex Components in Sorghum Reveals Loss of Pleiotropy in Tannin1
Tannin1 in sorghum does not act as a pleiotropic master regulator of leaf pigmentation or chilling tolerance, supporting a model of subfunctionalization of MBW components in panicoid grasses.
SbWRKY51 Positively Regulates Sorghum Salt Tolerance Through Coordinated Control of ROS Homeostasis and Lignin Biosynthesis
SbWRKY51, a group II WRKY transcription factor in sorghum, enhances salt tolerance by maintaining ion and ROS homeostasis and promoting lignin biosynthesis to strengthen cell wall integrity under salt stress.
Genomics-Assisted Breeding of Waxy Sorghum: Advances in Molecular Tools for Applications in the Food, Feed, and Biofuel Sciences
Mutations in the sorghum Waxy (GBSS) gene reduce amylose content and create value-added grain traits, and new genomic resources now enable more efficient breeding of waxy sorghum for food, feed, and biofuel applications.
Genetic Architecture and Breeding Implications of Partial Fertility in Sorghum Cytoplasmic Male Sterile Lines
Partial fertility in sorghum cytoplasmic male sterile lines is a complex, environmentally sensitive quantitative trait controlled by many minor-effect loci, which constrains genetic diversity in female parent lines and poses a major challenge for hybrid breeding.
