Functional characterization of AtGLP5 and AtSUC7, and their role in plant defense and development trade-offs in Arabidopsis thaliana

This study utilized the Arabidopsis thaliana-Sclerotinia sclerotiorum pathosystem to discover valuable rapeseed stem rot disease resistance engineering traits with activation-tagging, transgenic overexpressing, and T-DNA insertion knock-out mutants. By comparing their different disease resistance phenotypes and analyzing the expression of several pathway associated genes, we have got a relatively detailed knowledge about the molecular mechanism for the anti-pathogen function of the two proteins, AtGLP5 and AtSUC7. AtGLP5 is also further demonstrated to possess SOD activity and has a pivotal role in FLS2-associated flg22 signaling particularly. AtSUC7, previously regarded as a pseudogene encoding non-functional sucrose transporter, is proved to be involved in disease resistance and flowering time control.
