Improvement of other oil-seed crops


The mechanism of fatty acid biosynthesis and modification is common to all oil producing crops. However, in oil-rich fruit crops such as palm, coconut and avocado, oil is stored in a different way since it is used as an attractant for animals (fruit-oils accumulate as large irregular droplets of 20 µm, while seed oils are deposited as compact membrane-bound spheroidal droplets of 1-2 µm).

Due to this common mechanism, same results were obtained when same lipid-related transgenes were transferred to soybean or rapeseed. Similar results would also be expected in palm, coconut, etc. Therefore, available genes for improvement of oil can be used in other oil-seed crops and oil-rich fruit crops such as linseed and palm oil.

Transformation technology for rapeseed and soybean have already been developed and those for sunflower and linseed were still being developed in the year 1995. Therefore, eventually it should be possible to transform all the major annual oil-seed crops.

The transformation of the perennial oil crops, such as oil palm and olive is much more challenging, but the demand of oil palm will compel the development of transgenic palms for increased oil content and improved oil quality, particularly in major palm oil producing country, Malaysia. More genes involved in oil production will be isolated and utilized in a variety of oil producing crops in the coming decades.
