Unique Chromatin Regulators Discovered in Sorghum

In an effort to prove that epigenetics is behind some of sorghum’s specific features, researchers at Three Gorges University in China sought to clarify the function of the chromatin regulators and their interaction network.

Research Provides Support for Using Agricultural Configuration Techniques to Control Melanaphis sorghi

Researchers at Texas A&M University conducted a two year survey (2019-2020) of the abundance of Melanaphis sorghi and sorghum’s natural pest enemies in 42 sorghum fields located in the South Texas Gulf Coast.

The Epigenetics Behind the Adaptive Response of Sorghum to Phosphorus Deficiency

Recent studies have been successful in elucidating the genetic contributions underpinning the tolerance of some sorghum lines for low phosphorus conditions. Gladman and colleagues studied the environmental influence on how those genes work, known as epigenetics, under limiting phosphorus.

Researchers in Ethiopia Map QTLs for Stem Sugar and Stem Diameter in Sorghum

Scientists identify QTLs for average sugar content (oBrix) and stem diameter under both favorable rainy environmental conditions and unfavorable dry off-season conditions.

Physiological and Transcriptomic changes under Salt Stress in ‘Sodamchal’, a Korean Line of Sorghum

‘Sodamchal’, a line of Korean sorghum known for its salt sensitivity, was subjected to salt-stress. Physiological and transcriptomic changes were investigated to identify good candidates for stress indicators and candidate genes for the salt stress group.

Whole-genome sequencing of 400 Sorghum Association Panel (SAP) accessions establishes a crucial resource for dissecting genomic diversity in sorghum

Boatwright and coworkers generated about 44 million genetic variants in 400 SAP accessions using whole-genome sequencing.

Sorghum Gene Locus Confers Resistance to Colletotrichum sublineola and Other Fungi

Whole-genome resequencing of recombinant inbred lines (RILs) that were products of crosses between Colletotrichum sublineola (Cs)-resistant lines and Cs susceptible lines identified a locus that confers Cs resistance as well as resistance to other fungi.

Whole-genome resequencing of S. bicolor x S. halepense Cross Results in Increased Coverage of the Whole Chromosome and Presents New Targets for Future Research

Researchers used whole genome resequencing to “harness” the diversity and perenniality inherent in the wild Sorghum halepense line. The better variant distribution pattern in the present study opens up the opportunity for boosting gene and major marker discovery, particularly in the pericentromeric regions, on which there is little information.

New Tool for Gene Co-Expression and Visualization in Sorghum and Barley

Researchers from Ohio University developed PlantNexus, a gene co-expression network (GCN) and visualization interface for sorghum and barley. The gene functions and regulatory mechanisms that GCNs could help study are of fundamental importance in increasing nutrients and yield.
