**7.3 Nutritional studies of GMO crops**

It is important to assess the nutritional quality of genetically modified foods that consumed in human and animal feed. Assessment of nutritional quality composition of transgenic wheat (*Triticum durum* L.), corn (*Zea mays* L.), and tomato (*Lycopersicum esculentum* Mill.) were done compare with the non-transgenic control with a similar genetic background. No significant differences were observed for qualitative traits analyzed in wheat and corn samples [40]. Many studies have also been carried out with feed derived from GM plants with agronomic input traits in target animal species to assess the nutritive value of the feed and their performance potential. Studies in sheep, pigs, broilers, lactating dairy cows, and fish, comparing the *in vivo* bioavailability of nutrients from a range of GM plants with their near isogenic counterpart and commercial varieties, showed that they were comparable with those for near isogenic non-GM lines and commercial varieties [41]. In case of proteomic analysis creation of respective databases and algorithms of plant proteomic analysis is among the most important avenues of fundamental science aimed to predict the functions of genes and the properties of the products encoded by them [42].
