Abstract

2BS.2RL wheat-rye translocations have presented phenotypes of improved agronomic performance, such as Hessian fly resistance. The main objective of this work was to use two-dimensional electrophoresis to identify the proteomic differences between 2BS.2RL wheat-rye translocations and their recurrent parents. The investigation of seeds revealed line-specific protein spots, such as α-amylase inhibitor 0.19. More diverse expression patterns were observed in leaves than in seeds. Protein spots found specifically in 2BS.2RL, but not in non-2RL translocations were identified as β-glucosidase and vacuolar ATP synthase subunit B2, demonstrating the effects of translocated rye chromatin 2RL on common wheat genetic background. When the leaf protein spots were compared in the control and Hessian fly-infested near-isogenic line (NIL) (2BS.2RL), many down-regulated proteins and specific proteins, such as β-glucosidase, were detected in the latter.
