“…In contrast, trehalose, GABA, and methionine concentrations were highest in Miryang rice. These results corroborated previous research showing higher proline content in Suwon rice [25]. Under salt stress or dehydration, plants experience increased proline synthesis as a defense mechanism; the amino acid is thought to act as an osmoticum for adjusting water potential [26].…”

Resveratrol-enriched rice (RR) includes the stilbene synthase gene for resveratrol synthesis and the phosphinothricin-N-acetyltransferase gene for glufosinate tolerance. To investigate unintended effects resulting from RR's genetically modified chemical composition, 56 polar and nonpolar secondary metabolites were analyzed with gas chromatography-mass spectrometry in RR and conventional non-transgenic rice. Rice was cultivated during two seasons along three representative climatic regions in the Republic of Korea. Principal components analysis was used to visualize chemical composition differences among rice samples. The results showed that chemical composition was more influenced by growing year and location than by whether or not the rice was transgenic. Pearson's correlations and hierarchical clustering analysis also indicated no difference in the biochemical structures of RR versus non-transgenic rice. In addition, the glufosinate-ammonium treatment did not significantly change RR chemical composition.

“…The nutrient profile of the pregerminated mutant should still be evaluated to determine if there are differences compared with the wild type. Most comparative analyses of the nutritional composition of mutant or transgenic rice varieties were limited to comparing parameters such as proximate analyses, amino acids, minerals, vitamins, and anti-nutrient analyses [50,[65][66][67][68].…”

Comparative Nutritional Assessment and Metabolomics of a WRKY Rice Mutant with Enhanced Germination Rates

et al. 2023

Rice is the primary staple food for half the world’s population. Climate change challenges and food insecurity supports the need for rice with agronomically advantageous traits. We report on a transposon insertional rice mutant with enhanced germination rates. This trait is advantageous for rice growth in limited water regions and to reduce yield constraints caused by weed and bird competition. Evaluations of vital nutritional components, compositional analysis, and comparative metabolomics on threshed grain samples are performed, as these assays are those used to assess the safety of foods from genetically modified crops. Compared with the wild type (cv. Nipponbare), oswrky71 mutant grains have a similar size, shape, amount of crude fiber, crude fat, and ash content but higher crude protein. Mineral analyses reveal higher contents of phosphorus and zinc but lower calcium, potassium, sodium, and manganese in the mutant. Analysis of B vitamins reveals significantly higher riboflavin concentrations but lower choline chloride, calcium pantothenate, and thiamine. In addition, untargeted metabolomics analyses identify approximately 50 metabolites whose levels differed between the mutant and its wild type. Physical traits and compositional parameters analyzed are mostly similar and within the range or very close to being considered safe for consumption by the International Life Sciences Institute Crop Composition Database. Further agronomic evaluation and cooked rice sensory properties assessment are needed before positioning this mutant for human consumption.

“…A choline kinase ( CK1 ) gene isolated from Oryza sativa and the phosphinothricin acetyltransferase ( PAT ) gene from Streptomyces hygroscopicus have simultaneously been expressed in the OsCK1 GM rice (Lee et al, 2005 ). A comparative analysis of OsCK1 GM rice and its corresponding controls together with two commercial rice varieties was performed in two different locations in Korea (Park et al, 2015 ; Oh et al, 2016 ). In these results, significant differences between GM rice and its conventional counterpart were found for three minerals (Mg, P, and Na; Park et al, 2015 ).…”

Microelement contents and metabolism are vitally important for cereal plant growth and development as well as end-use properties. While minerals phytotoxicity harms plants, microelement deficiency also affects human health. Genetic engineering provides a promising way to solve these problems. As plants vary in abilities to uptake, transport, and accumulate minerals, and the key enzymes acting on that process is primarily presented in this review. Subsequently, microelement function and biosafety assessment of transgenic cereal plants have become a key issue to be addressed. Progress in genetic engineering of cereal plants has been made with the introduction of quality, high-yield, and resistant genes since the first transgenic rice, corn, and wheat were born in 1988, 1990, and 1992, respectively. As the biosafety issue of transgenic cereal plants has now risen to be a top concern, many studies on transgenic biosafety have been carried out. Transgenic cereal biosafety issues mainly include two subjects, environmental friendliness and end-use safety. Different levels of gene confirmation, genomics, proteomics, metabolomics and nutritiomics, absorption, metabolism, and function have been investigated. Also, the different levels of microelement contents have been measured in transgenic plants. Based on the motivation of the requested biosafety, systematic designs, and analysis of transgenic cereal are also presented in this review paper.
