The response of wheat and its microbiome to contemporary and historical water stress in a field experiment

H. Azarbad, L. D. Bainard, et al.

This field experiment highlights how 37 years of water stress history impacts wheat's microbial community, revealing that plant development stage and historical conditions are crucial under contemporary stress. Conducted by Hamed Azarbad, Luke D. Bainard, Asmaâ Agoussar, Julien Tremblay, and Etienne Yergeau, this research suggests that microbial-based strategies could enhance plant stress resistance.

Abstract

This field experiment assessed the impact of 37 years of contrasting water stress history on wheat's microbial response at two developmental stages under contemporary water stress. Amplicon sequencing revealed that plant development stage and water stress history were primary factors shaping the microbiome across plant parts under water limitation. Seeds showed divergent microbial communities based on historical conditions, modulated by contemporary environment and genotype. These findings highlight the potential of microbial-based strategies in plant breeding for stress resistance.
