Diploid- and tetraploid wall barley exhibit alternative molecular responses but comparable reproductive performance in response to different ambient temperature regimes.

Abstract excerpt

Diploid and allopolyploid relatives often differ in their responses to stressful or variable environments, but it remains unclear whether this is reflected in greater reproductive stability in such conditions, and whether any such advantage is associated with greater canalisation or plasticity of morphological and developmental traits or a more extensive transcriptional response. We tested this in the annual...
