Strategies for Transgenic Plant Selection
In this review, the use of the most common selection marker genes on plant transformation and the effects of their respective selective agents are discussed. These genes could be divided in two categories according their mode of action: genes for positive and negative selection. The retention of the marker gene flow through chloroplast transformation is also discussed. Further, strategies to re...
متن کاملMethods to produce marker-free transgenic plants.
Selectable marker genes (SMGs) have been extraordinarily useful in enabling plant transformation because of the low efficiency of transgene integration. The most used SMGs encode proteins resistant to antibiotics or herbicides and use negative selection, i.e., by killing nontransgenic tissue. However, there are perceived risks in wide-scale deployment of SMG-transgenic plants, and therefore res...
متن کاملProduction of Marker-free Transgenic Rice (Oryza sativa L.) with Improved Nutritive Quality Expressing AmA1
Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...
متن کاملMetacognitive beliefs and emotion regulation strategies: obese women with negative and positive body images
Women have higher vulnerability regarding to increase prevalence of obesity and its effect on people’s body image and women’s health on the society and future generations’ health is unquestionable role , negative body image influence on women’s eating habits and mental health, so aim of present research is to compare metacognitive beliefs and emotional regulation strateg...
متن کاملClean Vector Technology for Marker-free Transgenic Fruit Crops
Marker-free transgenic crops confer several advantages over transgenic crops equipped with selection genes coding e.g. for antibiotic resistance. Firstly, the European Union has prepared a guidance document for risk assessment of GM-crops to be introduced in the environment (E.U. Joint Working Group on Novel Foods and GMO’s, 2003). In this document based on compliance to consumer demands the EU...
