Cold-triggered induction of ROS- and raffinose metabolism in freezing-sensitive taproot tissue of sugar beet

I. Keller, C. Müdsam, C. Martins Rodrigues, D. Kischka, W. Zierer, U. Sonnewald, K. Harms, O. Czarnecki, K. Fiedler-Wiechers, W. Koch, H. E. Neuhaus, F. Ludewig, B. Pommerrenig

The paper compares freezing responses in sugar beet genotypes with different tolerance levels, finding that raffinose and its precursors accumulate in pith tissue of tolerant genotypes, suggesting a protective role against freezing damage.

Vernalization alters sugar beet (Beta vulgaris) sink and source identities and reverses phloem translocation from taproots to shoots

C. Martins Rodrigues, C. Müdsam, I. Keller, W. Zierer, O. Czarnecki, J. M. Corral, F. Reinhardt, P. Nieberl, F. Sommer, M. Schroda, T. Mühlhaus, K. Harms, U.-I. Flügge, W. Koch, F. Ludewig, , B. Pommerrenig

This study shows vernalization in sugar beets reverses sink-source dynamics by altering phloem translocation and gene expression, leading to sugar remobilization from taproots to shoots.
