Globally-deployed sorghum aphid resistance gene RMES1 is vulnerable to biotype shifts but being bolstered by RMES2

The paper assesses the vulnerability of the sorghum aphid resistance gene RMES1 to biotype shifts and finds it is bolstered by the presence of RMES2 and cyanogenesis.

Induced pluripotent stem cell derived pericytes respond to endogenous mediators of proliferation and contractility

This study compares iPSC-derived pericytes to primary human brain vascular pericytes, showing they express pericyte markers and respond to growth factors and vasoactive mediators, though with gene expression differences.

Automated analysis of PD1 and PDL1 in lymph nodes and the microenvironment of transmissible tumors in Tasmanian devils

This study uses QuPath to analyze PD1 and PDL1 expression in Tasmanian devil lymph nodes, finding higher PD1 expression in germinal centers and increased PD1-positive cells in DFT2 metastases.

Ecophysiological genomics identifies a pleiotropic locus mediating drought tolerance in sorghum

This study identifies a pleiotropic locus associated with drought tolerance in sorghum using GWAS, revealing genetic variants linked to yield components and water use under drought.

Autoimmune Alleles at the Major Histocompatibility Locus Modify Melanoma Susceptibility

This study shows that MHC-I autoimmune alleles are associated with reduced melanoma risk and later diagnosis age, independent of existing polygenic risk scores.

Quantitative and population genomics suggest a broad role of staygreen loci in the drought adaptation of sorghum

The paper identifies genetic loci associated with drought tolerance in sorghum using GWAS and shows their potential role in adaptation.

RNA silencing by CRISPR in plants does not require Cas13

The paper shows that CRISPR-Cas13 can reduce RNA in plants without the Cas13 protein, using a mechanism similar to RNAi.

The recent evolutionary rescue of a staple crop depended on over half a century of global germplasm exchange

The paper identifies a globally rare East African allele of RMES1 that conferred resistance to sugarcane aphids in Haitian sorghum, demonstrating the importance of global germplasm exchange for evolutionary rescue.

Crop modeling defines opportunities and challenges for drought escape, water capture, and yield increase using chilling-tolerant sorghum

The paper uses crop modeling to evaluate how early planting and chilling tolerance in sorghum affect drought escape, water capture, and yield in the central US sorghum belt.
