| Abstract/Contents: | "Previous work from this laboratory has demonstrated altered water relations in water-stressed turf (perennial ryegrass; Lolium perrene) infected with an endophyte (Acremonium lolii). In plants exposed to water deficits, lower leaf Ψs (i.e., greater solute accumulation) and, as a result, greater turgor pressure was maintained at a given relative water content. These results suggest that under water stress, endophyte infection may lead to greater leaf stomatal conductance (gs). Recent field studies suggest that the maintenance of leaf gs may be an important physiological mechanism which ameliorates the effects of summer stress on turf. The objective of the current work is to identify specific physiological responses and their underlying molecular mechanisms which transduce altered water relations in endophyte-infected turf into enhanced water stress resistance. Initial studies are focusing on big bluegrass (Poa ampla). Preliminary results suggest that in endophyte infected plants, altered water relations does lead to maintenance of greater gs under stress. Generation of subtractive cDNA libraries from water stressed infected and non-infected plants should identify specific plant genes whose translation products are associated with endophyte-induced stress resistance." |
