Microarray analysis on Brachypodium distachyon seedlings was performed to determine the response of the transcriptome to changes in ambient temperature, including identification of marker genes that were up-regulated or down-regulated by a moderate increase in growth temperature. Wild-type Brachypodium (Bd21) seedlings were grown on MSR63 media without sucrose (Alves et al. 2009 Nature Protocols vol. 4 pp 638-649) in a short-day photoperiod (14 hr light/ 10 hr dark) at 17 ºC. As the third leaf was emerging, plants were transferred to 12 ºC for 48 hrs. Plants were then maintained at 12 ºC or transferred to one of two temperature treatments: constant 22 ºC or constant 27 ºC. Samples were collected before the shift (0 hr) and at 2 hr and 24 hr after the shift and immediately frozen in liquid nitrogen. For each harvest, two to three replicates were collected that each contained 3 seedlings.
Experiment types
transcription profiling by array, co-expression, in vivo, stimulus or stress design
Thermal stress effects on grain yield in Brachypodium occur via H2A.Z-nucleosomes.
