Abstract

Plants are a major source of vitamins and micronutrients that required in human diet. However main food crops are usually deficient in important nutrients such as vitamins and microelements that deficiencies can cause series health problems. Biotechnology research has already demonsrated its potantial in enhancing the nutritional quality of our food. At this point, transgenic plants with enhanced provitamin A, vitamin C, vitamin E and ferritin content are promising for solving nutrition problems for human health. This review briefly summarise commercially grown transgenic crops and concentrates on new transgenic crops with enhanced nutritive value that might commercialized in near future.

VİTAMİN VE MİKROELEMENT İÇERİĞİ GENETİKSEL OLARAK ARTIRILMIŞ BİTKİLER

Abstract

Bitkiler beslenmemiz için gerekli olan vitamin ve mikroelementlerin temel kaynağıdır. Fakat her gün temel olarak tükettiğimiz bitkiler çoğunlukla eksikliğinde ciddi sağlık problemlerine sebep olabilen önemli vitamin ve mikroelementler yönünden fakirdir. Biyoteknolojik araştırmalar yiyeceklerimizin besin değerinin artırılmasında sahip olduğu potansiyeli çoktan göstermiştir. Bu noktada provitamin A, C vitamini, E vitamini ve ferritin miktarı artırılmış transgenik bitkiler insan sağlığı için beslenme problemlerinin giderilmesinde ümit vericidir. Bu derleme ticari olarak büyütülen transgenik bitkileri kısaca özetlemekte olup yakın gelecekte ticari amaçlı kullanılabilecek besin değeri artırılmış yeni transgenik bitkiler üzerine odaklanmıştır.
