Fig. 4.8.
Predominant gene expression profiles found during potato tuber development stages ranging from
longitudinal stolon growth to fully grown tuber size (a-f). Early downregulation of gene expression during the
switch from longitudinal stolon growth to first visible swelling (a); late downregulation of gene expression
after first visible swelling has been observed (b); early upregulation of gene expression during the switch
from longitudinal stolon growth to first visible swelling (c); late upregulation of gene expression after first
visible swelling has been observed (d); transient upregulation of gene expression during early tuber
organogenesis (e); and transient downregulation of gene expression during early tuber organogenesis (f).
Average gene expression level of non-differentially expressed genes is plotted as a reference in each
profile. (From Kloosterman
et al.,
2008.)
