Improvement in activation of Rubisco by Rubisco activase can potentially enhance CO 2  assimilation and photosynthetic efficiency in plants. The three homoeologous copies of  TaRca2-α  were identified on chromosomes  4AL ,  4BS  and  4DS  ( TaRca2-α-4AL ,  TaRca2-α-4BS , and  TaRca2-α-4DS ) in bread wheat. Expression patterns of the three copies at heading (Z55), anthesis (Z67) and grain-filling (Z73) stages were investigated through qRT-PCR analyses in a panel of 59 bread wheat genotypes and their effects on net photosynthesis rate (Pn), biomass plant -1  (BMPP) and grain yield plant -1  (GYPP) were further explored. Different but similar expression patterns were observed for the three copies of  TaRca2-α  at the three growth stages with highest expression at grain-filling stage.  TaRca2-α-4BS  expressed higher at the three stages than  TaRca2-α-4AL  and  TaRca2-α-4DS . The 59 genotypes could be clustered into three groups as high (7 genotypes), intermediate (41 genotypes) and low (11 genotypes) expression based on the expression of the three copies of  TaRca2-α  at three growth stages. Significant variations ( P <0.01) were observed among the three groups of bread wheat genotypes for Pn, BMPP and GYPP. Generally, the genotypes with higher  TaRca2-α  expression also showed higher values for Pn, BMPP and GYPP. The expressions of the three copies of  TaRca2-α  at heading, anthesis and grain-filling stages were positively correlated with Pn, BMPP and GYPP ( P <0.01) with stronger association for  TaRca2-α-4BS  at grain-filling stage. These results revealed that the expression of  TaRca2-α  contribute substantially to Pn, BMPP and GYPP, and suggested that manipulating  TaRca-α  expression may efficiently improve Pn, BMPP and GYPP in bread wheat and detecting  TaRca-α  expression levels with emphasis on  TaRca2-α-4BS  may be a positive strategy for selection in improving photosynthetic efficiency and grain yield of bread wheat.
