What is a GMO?

GMO stands for “genetically modified organism”. The genetics of virtually all plant-based food we eat today have been modified over time, so the term “GMO” could technically apply to all of them. When people talk about GMOs, they are often referring to genetic engineering.

Types of Genetic Engineering

A transgenic plant is one that contains a gene or genes which have been introduced artificially into the plant's genetic makeup using a set of several biotechnology techniques collectively known as recombinant DNA (rDNA) technology.[1]

Cisgenics involves only genes from the same species or a cross-compatible species, a process that could otherwise happen—though over a considerably longer period of time—through breeding or other natural methods. 

Cisgenics and transgenics can use the same genetic engineering techniques the only difference being the source of the genetic material.

The Arctic Apple® used a cisgenic technique called RNA interference or gene silencing to “turn off” the genes that make apples turn brown.
