Genomic basis of drought tolerance and yield in the Lolium multiflorum Tremona ecotype
This study investigates the Lolium multiflorum (Italian ryegrass) 'Tremona' ecotype from Ticino, Switzerland, which uniquely combines exceptional biomass productivity with strong drought tolerance. To determine the demographic history of L. multiflorum in Europe and uncover the genetic bases of this drought tolerance, we generated new genomic resources. This submission includes whole-genome short-read sequencing of 20 Tremona individuals to evaluate population diversity, alongside high-coverage long-read sequencing to generate a chromosome-level reference genome. Together, these data will help establish a framework for harnessing naturally evolved stress resilience and inform future forage grass breeding strategies.
