In order to characterize the response of selected grasses to water stress, relative water content (RWC) in leaves and quantum efficiency of photosystem 2 (Fv/Fm) were measured in Phleum pratense L., P.bertolonii DC.and P.
phleoides H.Karst.during 6 d of water stress.The results Bike Accessories - Bells indicated differential responses to water stress among the three Phleum species with higher water deficit sensitivity of P.
pratense and P.bertolonii than that of P.phleoides.The cDNA-amplified fragment length polymorphism (cDNA-AFLP) technique was applied to identify differentially expressed genes responding to water stress in P.
pratense.Cloned and sequenced differentially expressed fragments (DEFs) were used for primer design in order to identify orthologous genes in Lolium perenne L.Twelve genes orthologous to P.pratense DEFs were mapped in Loft Bin Storage the L.
perenne mapping population VrnA based on a high resolution melting curve analysis (HRM).This study provides genomic information about 29 differentially expressed genes after water stress in P.pratense and reports on the identification and mapping of twelve orthologs in L.perenne.
