Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Bioequivalence of Drugs: Drugs with Multiple Indications

Bioequivalence of Drugs: Drugs with Multiple Indications

The concept of therapeutic equivalence (TE) in drugs with multiple indications is complex. A generic drug may be therapeutically equivalent to a brand-name product for one specific indication, but this doesn't necessarily mean it's equivalent for all other indications. Evidence of TE in one patient group and bioequivalence shown in healthy volunteers can support—but not confirm—TE for other indications. However, definitive proof requires individual clinical studies for each indication due to...

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Bioequivalence: Overview

Bioequivalence: Overview

Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...

Equivalence: In Vitro and In Vivo Bioequivalence

Equivalence: In Vitro and In Vivo Bioequivalence

Bioequivalence studies are crucial in evaluating whether new drugs can match an approved one regarding pharmacological effects and clinical performance. These studies test if drugs, despite different dosage forms, share identical plasma concentration-time profiles. Three types of equivalence are central to these studies: chemical, pharmaceutical, and therapeutic. Chemical equivalence indicates that two or more drug products contain identical active ingredients in equal amounts. Pharmaceutical...

Multiple Comparison Tests

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Summary

Biotechnology-derived crops with combined insect protection and herbicide tolerance traits show compositional equivalence to conventional crops. Combining traits through breeding did not alter forage or grain composition, ensuring safety and nutritional status.

Background:

Compositional analysis is crucial for assessing the safety and nutritional value of biotechnology-derived crops.
Comparative analysis involves quantifying key nutrients, antinutrients, and metabolites against conventional counterparts.
Evaluating combined biotech traits requires assessing their impact on crop composition.

Purpose of the Study:

To assess the compositional equivalence of multitrait biotechnology-derived crops (MON 810 x NK603, MON 863 x MON 810, MON 863 x NK603, and MON 863 x NK603 x MON 810) compared to conventional controls.
To determine if combining insect protection and herbicide tolerance traits through conventional breeding influences forage and grain composition.
To ensure the safety and nutritional integrity of crops with multiple stacked biotechnology traits.

Main Methods:

Quantitative measurement of nutrients, antinutrients, and secondary metabolites in forage and grain.
Statistical comparison of compositional data between multitrait biotechnology-derived crops and their near-isogenic conventional controls.
Analysis of 241 statistical comparisons, assessing differences against a 99% tolerance interval.

Main Results:

192 out of 241 (79.7%) compositional comparisons showed no statistically significant differences (p > 0.05).
All 49 statistically significant differences fell within the established 99% tolerance interval for commercial hybrids.
No significant compositional variation was observed due to the combination of insect protection and herbicide tolerance traits.

Conclusions:

Multitrait biotechnology-derived crops are compositionally equivalent to their conventional counterparts.
Conventional breeding of combined insect protection and herbicide tolerance traits does not introduce unintended compositional changes.
The safety and nutritional status of these combined-trait crops are comparable to conventional varieties.
