| Abstract/Contents: | "Zoysiagrass (Zoysia spp.) are warm season turfgrasses desirable for recreational and ornamental purposes due to their relatively low input requirements and wide general tolerance to drought, shade and salinity. Although the most freeze tolerant of the warm season grasses, the commercial spread of zoysiagrass is mostly limited to the transition zone and the southern US. The leading freeze tolerant cultivar, Meyer, was developed in the 1950's, and although some progress has been made in breeding for freeze tolerance in zoysiagrass, the pool of cultivars with high levels of freeze tolerance is still limited. To deepen our understanding of the physiologic and metabolic components of freezing tolerance in zoysiagrass, a transcriptomic approach was utilized to identify genes involved in cold acclimation, a critical step in the development of freezing tolerance. Meyer, a freeze tolerant cultivar, and Victoria, a free susceptible cultivar were used to assess transcriptomic response to cold acclimation. Ninety-six pots, forty-eight pots per cultivar, were subjected to either a cold acclimation or non-cold acclimation treatment. Leaf samples collected after 48 hours into treatment were taken and the RNA was extracted, then sequenced. Illumina sequencing results were analyzed in correspondence with the zoysiagrass reference genome to determine differential gene expression. Genes of interest for cold acclimation were identified." |
