What is RBCS1 expression in coffee: Coffea orthologs, Coffea arabica homeologs, and expression variability between genotypes and under drought stress about?
## Background In higher plants, the inhibition of photosynthetic capacity under drought is attributable to stomatal and non-stomatal (i.e., photochemical and biochemical) effects. In particular, a disruption of photosynthetic metabolism and Rubisco regulation can be observed. Several studies reported reduced expression of the __RBCS__ genes, which encode the Rubisco small subunit, under water stress. ## Results Expression of the __RBCS1__ gene was analysed in the allopolyploid context of __C. arabica__, which originates from a natural cross between the __C. canephora__ and __C. eugenioides__ species. Our study revealed the existence of two homeologous __RBCS1__ genes in __C. arabica__: one carried by the __C. canephora__ sub-genome (called __CaCc__) and the other carried by the __C. eugenioides__ sub-genome (called __CaCe__). Using specific primer pairs for each homeolog, expression studies revealed that __CaCe__ was expressed in __C. eugenioides__ and __C. arabica__ but was undetectable in __C. canephora__. On the other hand, __CaCc__ was expressed in __C. canephora__ but almost completely silenced in non-introgressed ("pure") genotypes of __C. arabica__. However, enhanced __CaCc_
