Erratum: Combination of Developmental Behaviors and Transcriptome Reveals Differential Response Mechanisms of Phytophthora sojae to Aspartic Acid and Glucose in Seed Exudates

Isoflavones in soybean seed and root exudates are host-specific signal molecules for to recognize host soybean. G protein and calcium signaling pathway are involved in the chemotaxis of zoospores in the recognition of isoflavones. To investigate the role of host nonspecific signaling molecules (sugars and amino acids) in seed and root exudates in zoospore chemotaxis and mycelial growth, the transcriptome of responding to aspartic acid (Asp) and glucose (Glc) was analyzed by the RNA-seq method. We found that the relative in situ concentrations of amino acids and sugars significantly promoted zoospore chemotaxis, as do isoflavones. Transcriptomics showed that both similarity and difference existed in response mechanisms of to Asp and Glc. Asp and Glc activated mitogen-activated protein kinase signaling pathway and phosphatidylinositol signaling system but not G-protein signaling pathway, which have been reported to be responsible for zoospore chemotaxis. In addition, ubiquitin-mediated proteolysis and ATP binding cassette transporters were also activated by Asp and Glc. Meanwhile, glutathione signaling pathway uniquely participated in the response of to Asp but not involved in the response process to Glc, which is waiting for further study. Our results provide new insights into the molecular mechanism of zoospore response to Asp and Glc.
