Spatial expression patterns of genes encoding sugar sensors in leaves of C4 and C3 grasses.

This comprehensive transcriptomic study provides an initial foundation for elucidating sugar sensing genes within major C4 and C3 crops. This study provides some evidence that C4 and C3 grasses do not differ in how sugars are sensed. While sugar sensor gene expression has a degree of stability along the leaf, there are some contrasts between the mesophyll and bundle sheath cells.
