Linking microbial community structure with function using amplicon sequencing of the NRPS genes associated with wheat roots under drought stress

Ying Guan, Edmond Berne, Rosanna C. Hennessy, Paolina Garbeva, Mette Haubjerg Nicolaisen, Frederik Bak

The paper uses amplicon sequencing of NRPS genes and 16S rRNA to study microbial community structure and function in wheat root rhizoplane under drought stress, finding that drought affects siderophore composition and enriches NRPS genes linked to colonization.
