The temporal foliar transcriptome of the perennial C3 desert plant Rhazya stricta in its natural environment.

Background The perennial species Rhazya stricta (R. stricta) grows in arid zones and carries out typical C3 photosynthesis under daily extremes of heat, light intensity and low humidity. In order to identify processes attributable to its adaptation to this harsh environment, we profiled the foliar transcriptome of apical and mature leaves harvested from the field at three time periods of the same day.
