Safety verification of genetically modified rice morphology, hereditary nature, and quality

Abstract

Background The drought environment occurs frequently due to the unpredictable future climate change, and drought has a direct negative impact on crops, such as yield reduction. Drought events are random, frequent, and persistent. Molecular breeding can be used to create drought-tolerant food crops, but the safety of genetically modified (GM) plants must be demonstrated before they can be adopted. In this research, the environmental risk of drought-tolerant GM rice was explored by assessing phenotype and gene flow. Drought resistance genes CaMsrB2 inserted HV8 and HV23 were used as GM rice to analyze the possibility of various agricultural traits and gene flow along with non-GM rice. Results When the traits 1000-grain weight, grain length/width, and yield, were compared with GM rice and non-GM rice, all agricultural traits of GM rice and non-GM rice were the same. In addition, when the germination rate, viviparous germination rate, pulling strength, and bending strength were compared to analyze the possibility of weediness, all characteristic values of GM rice and non-GM rice were the same. Protein, amylose, and moisture, the major nutritional elements of rice, were also the same. Conclusions The results of this research are that GM rice and non-GM rice were the same in all major agricultural traits except for the newly assigned characteristics, and no gene mobility occurred. Therefore, GM rice can be used as a means to solve the food problem in response to the unpredictable era of climate change in the future.

Volunteer Plants’ Occurrence and the Environmental Adaptability of Genetically Modified Fodder Corn upon Unintentional Release into the Environment

“…In addition, the viviparous germination rate was higher in Daehakchal than in Gwangpyeongok. Therefore, the possibility of weediness of the grains due to unintentional release into the environment was low, in line with Joen and Park [36].…”

Stability of Transgene Inheritance in Progeny of Field-Grown Pear Trees over a 7-Year Period

“…The transgenic progeny's seed shape (length:width) did not change either. Stable grain shape and the absence of changes in grain weight and germination in rice with a drought resistance gene CaMsrB2 grown in the field for two years under irrigation or drought provided the grounds to conclude that the rice was suitable for commercial cultivation [55].…”

Spatial Lipidomics of EPSPS and PAT Transgenic and Non-Transgenic Soybean Seeds Using Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging

“…Currently, DNA/cDNA microarrays, microRNA fingerprinting, electrophoresis, nuclear magnetic resonance (NMR), and gas or liquid chromatography coupled to mass spectrometry (GC/MS or LC/MS) are the most commonly used techniques for transcriptomic, proteomic, and metabolomic studies of transgenic crops. ,, One goal of these increasing numbers of non-targeted studies is to evaluate the unintended effects of transgenic plants, such as transgenic soybean, , Arabidopsis , , maize, , rice, , wheat, potato, , tomato, , tobacco, lettuce, and cucumber . For these general “omic” studies, most analyses are performed on the endogenous compound extract from the whole organs or whole plant tissues followed by subsequent characterization with these “omic” techniques, resulting in the loss of spatial information during the extraction process .…”
