520 |a Warm- and cool-season turfgrasses were originated from different locations with contrasting heat tolerance. The molecular mechanisms of heat tolerance have not been extensively studied in turfgrass species. In this study, transcriptomic analysis showed that bermudagrass was more tolerant to heat stress as evidenced by lower contents of H2O2, proline and glutathione than those in tall fescue after heat treatment. RNA sequencing analysis revealed that 32.7% and 17.7% more genes were changed in tall fescue than in bermudagrass after 2 and 12h heat treatment, respectively. GO terms of redox were enriched in bermudagrass whereas metabolite transportation ones were over-represented in tall fescue after 2h treatment. Ubiquitin dependent degradation pathways were commonly regulated in both grass species. CdF-box and FaF-box transgenic Arabidopsis exhibited improved tolerance to heat stress. Regulatory elements analysis revealed that four ABA-responsive elements present in CdF-box promoter, indicating CdF-box could be potentially regulated by ABRE binding factors (ABFs). All these findings provide evidences for understanding heat stress response in warm- and cool-season grass species
