Abstract

The roots of Platycodon grandiflorum species either dried or fresh, are used as an ingredient in salads and traditional cuisine in Korea. To interpret the root proteins, a systematical and targeting analysis were carried out from diploid and tetraploid roots. Two dimensional gels stained with CBB, a total of 39 differential expressed proteins were identified from the diploid root under in vivo condition using image analysis by Progenesis Same Spot software. Out of total differential expressed spots, 39 differential expressed protein spots (≥ 1.5-fold) were analyzed using LTQ-FTICR mass spectrometry. Except two proteins, the rest of the identified proteins were confirmed as down-regulated such as Isocitrate dehydrogenase, Proteasome subunit alpha type-2-B. However, the most of the identified proteins from the explants were mainly associated with the oxidoreductase activity, nucleic acid binding, transferase activity and catalytic activity. The exclusive protein profile may provide insight clues for better understanding the characteristics of proteins and metabolic activity in various explants of the economically important medicinal plant Platycodon grandiflorum.
