Proteome study of heterosis phenomenon in bread wheat

Bread wheat is one of the most important plant and hybrid varieties plays an important role with regard to the food supplement in the world. Some of the traits of wheat that show significant differences in hybrid more than parents should be responsible for the observed heterosis. This phenomenon is controlled by genes/proteins that identification of these genes in molecular approach is important issue for plant breeding projects. The purpose of this research is identification of heterosis related proteins in bread wheat via proteomics. Three varieties, zagros, N8118 and their hybrid were cultured in randomized complete block design in 3 replications. Morphological analysis with SPSS shows significant difference between hybrid and parents in stem length and spike length. Also the results of proteomics show that the expression of one protein spot has changed in type of position shift in zagros variety and this spot is related to cytochrome b6/f complex. This protein plays an important role in production of ATP and NADPH in photosynthesis pathway.
