Other thoughts that the development of tissue culture for providing seaweed seed has been considered as 'a solution', especially if we want a better quality of seeds compared to those from nature.
Does it really work that way?
Then how about the food safety issue if the products come fro tissue culture?
I need insights from the experts in this field.
Thank you.
Is tissue culture from the somatic embryogenesis really a solution and safed to be comercially developed?
Somatic embryogenesis can be used for its convenience and for the process to clean up the culture from unwanted contaminants. The process can center on a single source cell and can have issues with restricted genetic biodiversity. This genetic uniformity can make the increase of uniform product susceptibity to pathogens pests and environmental changes which may arise. The potential of doing diverse clones in mixtures is a potential strategy for having more adaptable products for natural applications or farming situations. Overly uniform genetic resources can also have problems for genetic stability. Natural products which come from sexual recombination would have more disuniformity except if inbred lines were developed and heterotic patterns were identified as done in the hybrid seed industry for a crop like maize. Hybrids are very notable for being able to increase the performance and ability in the right heterotic patterns. The identification of superior parental lines and the identification of heterosis and the use of a blend of superior hybrid lines would be able to give the best of all worlds.
Somatic embryogenesis is one of the pathway of micropropagation. This process includes the development of callus followed by embryogenic callus (Nodular Callus) and finally the development of somatic embryos. From this stage plants can be produced through germination of somatic embryos or the embryos can be multiply at will to get more plants in short time. From callus stage to somatic embryogenesis, the callus cell dived rapidly to form irregular callus tissues. During this process, there are chances that, nuclear division is not followed by cytokineses leading to the formation of multi nucleate cell which may leads to the formation tetraploids. This is the expected variation.
Paul Reed Hepperly so basically, the seaweed produced from this somatic embryogenesis has the same characteristic as the parental, isn't it?
Maybe this paper can help :
