Expression of <i>Ph</i>. <i>infestans</i> and <i>Py</i>. <i>ultimum</i> genes involved in starch and inositol phosphate degradation, the pentose phosphate pathway, and gluconeogenesis during tuber infection.

(A) Genes encoding α-amylase (left) and γ-amylase (right). From left to right, the bars in each graph represent early tuber infection by Ph. infestans (PH, orange bar), early tuber infection by Py. ultimum (PY, light purple), late tuber infection by Ph. infestans (red), and late tuber infection by Py. ultimum (dark purple). Transcript levels are expressed as relative mRNA values based on the aggregate FPKM of genes in each category, with the mean equaling 1.0. (B) Genes encoding rate-limiting steps in the pentose phosphate pathway. (C) Genes that remove phosphate from phytic acid and other inositol phosphates. These include two activities that release phosphate (EC 3.1.3.2 and EC 3.1.3.62) and two that convert ADP to ATP (EC 2.7.1.134 and EC 2.7.1.158). (D) Genes encoding rate-limiting steps in gluconeogenesis.
