Abstract
|
|
|
|
Engineering microalgae has opened a new era for plant biologists and biotechnologists. Microalgae had been proved as a promising candidate for the production of biopharmaceuticals, nutraceuticals, antioxidants, antimicrobial and antiviral compounds, in dyeing and food industry as well for biofuel production. Genetic transformation of some important microalgae has been successful, but several other potential microalgae species still need scientific attention. The success of the genetic transformation depends mainly on the utilization of the selectable and screenable markers. Like for other higher crop plants, several useful markers have been reported for microalgae transformation. In this follow-up, we compared different marker genes for genetic engineering of approximately all the industrially important microalgae. We have discussed the expression host, the targeted genome, appropriate selection agent, as well as the transformation method. Genetic transformation is an expensive and labor intensive process and this review will aid to shorten the time span by providing a database of appropriate markers for microalgae research which could serve as a guide for those involved in the genetic engineering of microalgae.
