Summary: Paspalum notatum Flüggé is a perennial grass widely used as forage and as turf in many countries as Argentina, Australia, United States and in the South of Brazil. The species present diploid and tetraploid citotypes with x=10 chromosomes. Transcriptomic and differential gene expression (DGE) studies in plants, under water deficit, are used to investigate the molecular mechanisms of transcriptional regulation and potential genes involved in the response to drought, making possible the genetic modification and/or gene editing of Paspalum and other plants of commercial interest, as already done in bahiagrass and maize. The objective of this study is to evaluate the gene expression profile of Paspalum notatum Flüggé in response to drought. The tetraploid accession P. notatum BGP 216 conserved at the germplasm bank of Embrapa Pecuária Sudeste (São Carlos, Brazil) was selected for a drought stress experiment based on the climate characteristics of its site of collection, on the importance of the species and on the ability of the species to tolerate drought.
