GGTA2P and infection: Candidates GLRG_11091 (HGT2) and GLRG_11966 (HGT2) of C. graminicola and candidates CH063_02340 (HGT2), CH063_10640 (HGT2) and CH063_01625 (HGT5) of C. higginsianum are strongly upregulated at the PA and BP time points which are very early in the infection process, suggesting a role in plant penetration or establishment of infection (Additional file 2: Table S2).
