A comprehensive analysis identified 112 Sorghum NAC genes, characterized their phylogenetic distribution and structural diversity, and uncovered nine greenbug-inducible SbNAC genes, shedding light on their potential roles in sorghum defense against aphids.

HPC-GVCW offers a high-performance computing-based workflow for rapid SNP detection in major crops, significantly reducing execution times and facilitating the exploration of genetic diversity essential for molecular-assisted selection breeding programs.

This study on Sorghum bicolor and Arabidopsis thaliana extracellular vesicles reveals partial conservation in protein content, providing crucial insights into the dynamic nature of intercellular communication and defense responses in plant cells.

Spike-in normalization improves the accuracy and reliability of differential gene expression analysis in plant RNA-Seq experiments, particularly under conditions where experimental factors significantly influence gene expression dynamics.

Pilot-scale genome-wide association mapping in diverse sorghum germplasms uncovered 42 significant quantitative trait nucleotides (QTNs), revealing novel candidate genes influencing major agronomic, root, and stomatal traits such as plant height, dry biomass, and plant yield.

Genetic architecture of anthracnose resistance genes (ARG4 and ARG5) shown to confer resistance in SAP135 and P9830. Susceptible varieties lack these genes through presence-absence variation and recessive alleles.

The study delves into the sorghum MYB gene family, underscoring the key role of SbMYBAS1 in negatively regulating salt tolerance through reduced ROS scavenging ability and K+ content.

Genetic insights unveiled from comparing the root system architectures of sorghum and maize under drought, salt and nutrient deficiencies will pave the way for improved crop varieties resilient to abiotic stresses in a changing climate.
