The Non-Pathogenic Strain Fusarium oxysporum FO12 Mitigates Simultaneous Verticillium dahliae and Iron Deficiency Stresses in Arabidopsis thaliana.

ABSTRACT: Verticillium wilt, caused by the soilborne fungus Verticillium dahliae, and iron (Fe) deficiency are major stresses impacting valuable crops in the Mediterranean basin. The plant response to these stresses consists of overlapping pathways that, coupled with the emerging use of endophytic fungi as biological control agents (BCAs) and plant biostimulants, enables the study of their potential to mitigate co-occurring biotic stresses and nutritional deficiencies such as Fe deficiency. To this end, Arabidopsis thaliana plants of the "Columbia" ecotype grown in calcareous soil were inoculated with the non-pathogenic strain Fusarium oxysporum FO12 and/or with the defoliating pathotype of V. dahliae strain V180. Plant growth, plant mineral uptake, and disease progression, along with the molecular
