Cytology of Potato Callus Cells in Relation to their Frost Hardiness

Structure of callus cells of frost-sensitive and frost-tolerant Solanum species and a frost-tolerant cell line (D20-1), selected from S. tuberosum cv. Desirée callus, was studied. Like frost-tolerant species S. commersonii, cells of the frost-tolerant cell line contained starch grains in their plastids. The cells of this frost-tolerant line also possessed an increased number of microbodies containing protein crystals which suggests the involvement of proteins in frost tolerance but the mechanism may differ from that in frost-tolerant species.

Keywords: frost tolerance; microbodies; proteins; Solanum
Subjects: frost hardiness and tolerance, callus cell cytology; in vitro culture, frost tolerance; microbodies, frost hardiness, callus culture; potato; proteins, frost hardiness; Solanum acaule; Solanum commersonii; Solanum tuberosum
