Vesicle Trafficking Patterns in Developing Peanut Fruits Related to Aspergillus flavus Resistancy and Development

Abstract: Innate immunity mediated by vesicle trafficking plays important roles in plant defense. In this study， using QPCR and bioinformatics methods， we demonstrated that two different distinctive vesicle trafficking patterns played major function in peanut developing seeds of A. flavus resistant strain C20R and sensitive strain TFR. We also found that VAMP726 and RMR were the preferred vesicle trafficking components in A. flavus resistant strain C20R， and VSRs VTI1a， b in A. flavus sensitive strain TFR. During fruit developmental process， the dynamic transcription tendency of these vesicle trafficking components was consistant to that of sets of genes in the developing seeds of C20R and TFR respectively at whole genomic transcription levels. Thus， we proposed that two vesicle transport patterns existed in C20R and TFR developing seeds respectively， which was related to the expression differences at whole genomic transcription levels in the developing seeds between C20R and TFR. Such differences could begin as early as at the end of protein synthesis and at the entry of ER as the begining of transport pathway.
