| Abstract/Contents: | "Our previous studies have shown that thermal Agrostis scabra collected from the thermal sites in Yellow Stone National Park was better tolerant to heat stress than Agrostis palustris. This study was designed to compare their gene expression profiles between these two species using differential display analysis (Delta Differential Display Kit). Total RNA was extracted from leaves exposed to a normal growth temperature (20°C, control) or to 40°C for a week (heat stress). With the transcript cDNA, 20 pairs of primers were tested. Forty-two down regulated and Forty-four up regulated gene fragments were identified in both species. Of the up regulated gene fragments, 13 were found only in the thermal species, A. scabra. Sequence analysis of some genes fragments showed that the down-regulated genes are more related within photosystem chain, but up-regulated genes are highly involved in the signaling pathway as other stress, such as signaling/regulatory components, and target gene expression involved in the secondary metabolism. All these cloned fragments are in the confirmation by northern or virtual northern hybridization." |
