Other plant actin promoters
Rice actin promoters have been shown to be strong in directing gene expression in graminaceous monocotyledonous plants. However, their function in certain non-graminaceous monocots are variable suggesting that the activity of actin promoters may be limited to closely related species. Therefore, Researches were also carried out to identify actin promoters from other plant species. So far, patents have been issued and patent applications have been filed on actin promoters from the plant species including banana, melon, maize andArabidopsis.
Queensland University of Technology filed patent applications in the United States and Australia on an actin promoter from banana and its use.
Exelixis Plant Sciences, Inc. obtained patents in United States and Australia on a melon actin promoter.
Monsanto owns two United States patents and one Australian patent claiming Arabidopsis actin promoters and their use as part of the invention. In addition, Monsanto also filed patent applications on actin regulatory elements from rice and maize in the United States and Europe.
