Transcription profiling by microarray of barley mutant (G132) and its wild type (Hordeum vulgare cv. Graphic) under high CO2 concentration


ABSTRACT: This experiment showed the microarray expression of a barley recessive mutant (G132) and its wild type (Hordeum vulgare cv. Graphic) under high CO2 concentration. The homozygous mutation has a strong pleiotropic nature affecting many aspects of plant. In order to identify target genes of this mutation, changes in gene expression of mutant and its responses to elevated CO2 were compared to wild type.

The mechanisms of stomatal sensitivity to CO2 are yet to be fully understood. The role of photosynthetic and non-photosynthetic factors in stomatal responses to CO2 was investigated in wild-type barley (Hordeum vulgare var. Graphic) and in a mutant (G132) with decreased photochemical and Rubisco capacities. The CO2 and DCMU responses of stomatal conductance (gs), gas exchange, chlorophyll fluorescence and levels of ATP, with a putative transcript for stomatal opening were analysed. G132 had grea  ...[more]
