Vitamin B6 is a vitamin required for organisms as a substrate in metabolic reactions. While it is available from the plant dietary resources, the availability of the vitamin in the edible portions of the consumed plants is insuf??cient to meet the daily recommended doses. Genetic engineering techniques have proven successful in increasing the vitamin B6 content in the model plants.

In their study, a research team led by Deepak Singh Bagri from the Dr. Harisingh Gour Central University in India aimed to develop a transgenic potato (Solanum tuberosum) overexpressing the PDXII gene, a key vitamin B6 pathway gene from Arabidopsis thaliana. The resulting transgenic potato tubers exhibited a significant improvement in vitamin B6 content, reaching as high as a 150% increase, compared to the control potatoes.



The significant increase in vitamin B6 content of the transgenic potato was also found to be associated with resistance to abiotic stresses, including salt stress.
