In the past, a method using Agrobacterium was common among transgenic grains. The tissue of the plant would be inserted with Agrobacterium which would transfer the DNA to it's host (the plant). This tissue would then be spread throughout the entire plant. Unfortunately, this technique could only be used in certain grains.
A new approach to genetically modifying plants has been found. Researchers combined morphogenic genes and genes that were chosen for genetic modification in grains.
When they did so, transformation rates increased for a large number of maize cultivators-- in many cases going from essentially no transformation to rates high enough for efficient use in commercial and research applications.
This technique can be conducted in multiple species of plants including sorghum, rice, and sugarcane. Transgenic plants is a very controversial topic, but I believe that for some species it is necessary. Humans have a very high consumption rate for some plants, many being grain, and mass production is needed to stay consistent with these rates. Transgenic plants allow for more product to be gathered and more variations of a plant to be obtained. This new technique could prove to be very beneficial to our population.
