Genome-wide characterization and expression analysis of the MLO gene family sheds light on powdery mildew resistance in Lagenaria siceraria.

ABSTRACT: MLO (mildew locus O) genes play a vital role in plant disease defense system, especially powdery mildew (PM). Lagenaria siceraria is a distinct Cucurbitaceae crop, and PM is one of the most serious diseases threatening crop production and quality. Although MLOs have been exploited in many Cucurbitaceae species, genome-wide mining of MLO gene family in bottle gourd has not been surveyed yet. Here we identified 16 MLO genes in our recently assembled L. siceraria genome. A total of 343 unique MLO protein sequences from 20 species were characterized and compared to deduce a generally high level of purifying selection and the occurrence of regions related to candidate susceptibility factors in the evolutional divergence. LsMLOs were clustered in
