573 | Adalatzadeh-Aghdam and Toorchi REVIEW PAPER OPEN ACCESS Investigation of heterosis using proteomic approach

Heterosis is a common phenomenon in which the F1 – hybrid of plants display superior agronomic performance compared to the inbred parental lines. For better understanding of the molecular mechanisms of plant heterosis, recently, different tissue of plant has been compared using proteomic approach between hybrid and their parental inbred lines. The patterns of plants proteome were analyzed by different software and proteins were identified by mass spectrometry/Edman sequencing method. Differential expressed proteins could be categorized in different functional classes and study of their dynamic regulation at different developmental stages could be responsible for heterosis in some plants
