Corrigendum: Genes Involved in Stress Response and Especially in Phytoalexin Biosynthesis Are Upregulated in Four Malus Genotypes in Response to Apple Replant Disease

Corrigendum on: Reim, S., Rohr, A.-D., Winkelmann, T., Weiß, S., Liu, B., Beerhues, L., et al. (2020). Genes involved in stress response and especially in phytoalexin biosynthesis are upregulated in four Malus genotypes in response to apple replant disease. Front Plant Sci 10, 73. doi: 10.3389/fpls.2019.01724 traud.winkelmann@zier.uni-hannover.deIn the original article, there was a mistake in Figure S2 as published. The mistake included the labeling of two steps in the proposed biosynthesis pathway of biphenyl and dibenzofuran phytoalexins. The corrected Supplementary DataSheet 2 appears below. Table In Table S2 of the published article, single amplicon sizes were given incorrectly. They have been corrected.Following a reader's comment, specificity of two primer pairs was tested by sequencing. A paragraph was added to MATERIAL AND METHODS, Primer Selection and RT-qPCR Validation in paragraph 2:To test the specificity of the primers used to amplify the genes B4Ha and B4Hb (Table S2), an amplicon deep sequencing was conducted. The sequence analysis proved the B4Hb primers to be highly specific. The sequencing results also showed that the B4Ha amplicon is present in both B4Ha and B4Hb. This means that the primers for B4Ha are not gene-specific. This limited specificity should be considered for the interpretation of the respective data.
