Comparative Study of Drought Tolerant Biotech Rice and Non-biotech Counterpart
September 10, 2014| |
Scientists from Kyungpook National University in South Korea compared the vegetative and reproductive traits as well as antioxidant properties of drought tolerant biotech rice lines (HV8 and HV23) and its non-biotech counterpart (Ilmi). The findings were presented at Journal of Agronomy and Crop Science.
According to the research article, the grain size and weight, seed germination, root length, root and shoot dry weight, length and width of flag leaf, plant height, and ligule, stamen and carpel length were not significantly different. Onset and completion of heading in each line happened almost during the same period. The antioxidant properties in terms of DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and polyphenol content were not statistically different under similar treatment condition.
Based on the results, the transgenic rice lines containing CaMsrB2 gene were equivalent to their non-transgenic counterpart without any visible unintended effects.
