Insight to the conventional and biotechnological approaches in tomato on potato grafting (Pomato): A review

Pomato is the result of a combination of a tomato scion and a potato rootstock. This grafted combination is also acknowledged as a horticultural magic plant, a recombinant double harvest plant, or a chimeric double harvest plant. This type of plant could meet the need for proper vertical resource usage in the future, as urbanization is increasing rapidly and agricultural land is now becoming rare and expensive. Moreover, even though changes in the environment are the most substantial real limitation in vegetable production, this category of graft could be employed as an alternative strategy. Few reports on using somatic interbreeding to establish tomato-potato fusion hybrids have been available since the early 1900s. This strategy can be used again in the future to save time and convenience during labor-intensive procedures, as this plant can indeed be established through any other technique, instead of trying to make grafting and somatic combination the only reasonable alternatives. The grafted union of tomato and potato has indeed positively influenced output, reliability, hormone levels, signaling pathways, and mechanisms. This paper has been reviewed to gather all information available on the tomato plant to date, since there has been some experimentation over the past few decades.
