This study shows that methionine auxotrophic Agrobacterium strains improve switchgrass transformation by reducing bacterial overgrowth and enabling longer co-cultivation periods.

This study identifies plant-derived insulator-like sequences that reduce ectopic transgene expression but also decrease promoter effectiveness, suggesting they function as silencers with potential utility in plant transformation.

This paper develops mPing-based activation tags for crop insertional mutagenesis, showing they can induce gene overexpression and improve mutagenesis effectiveness.

This study examines genome damage in rice and maize after biolistic transformation, finding that some events result in large-scale chromosomal alterations and repair via homology-dependent mechanisms.
