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

Abstract

In 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 Figure S2 appears below. Figure S2 has been updated in the original article. In Table S2 of the published article, single amplicon sizes were given incorrectly. They have been corrected, and a corrected Table S2 file is published. Following a reader’s comment, specificity of two primer pairs was tested by sequencing. A paragraph was added toMaterial AndMethods, Primer Selection and RT-qPCR Validation after 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. The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated. (Figure presented.).
