In this regard, Yi et al. [56] reported a considerable upregulation of GLU expression in pepper roots when treated with 2,3-butanediol before its infection with Ralstonia solanacearum. Moreover, the overexpression of the PR genes, phenylalanine ammonia-lyase (PAL) and systemic acquired resistance 8.2 (SAR8.2), were also observed. Here, TMEM37 is linked to infection.
