Rice tolerance to suboptimal low temperatures relies on the maintenance of the photosynthetic capacity
The purpose of this research was to identify differences between two contrasting rice cultivars in their response to suboptimal low temperatures stress. A transcriptomic analysis of the seedlings was performed and results were complemented with biochemical and physiological analyses. The microarray...
