Abstract

Pantoea agglomerans isolates 3 and 4 were retrieved from the bacterial community associated with wheat seeds. These isolates differ in their pattern of growth antagonism toward Alternaria species. A comparison of the genome sequences of these two isolates revealed a high sequence identity with previously sequenced strains of P. agglomerans.

Highlights

  • Previous work examining the epiphytic microbiome of Triticum spp. and Brassica spp. identified strains of Pantoea agglomerans with differential growth antagonism phenotypes when cultured with fungi, such as Alternaria sp. and Leptosphaeria maculans (1)

  • To examine the mechanisms by which isolate 4 may inhibit the growth of fungal pathogens, we determined the genome sequences of these two isolates

  • P. agglomerans isolates were grown at 28°C in a rotary shaker for 24 h in BBL Trypticase soy broth (Becton, Dickinson, Cockeysville, MD)

Summary

Introduction

Previous work examining the epiphytic microbiome of Triticum spp. and Brassica spp. identified strains of Pantoea agglomerans with differential growth antagonism phenotypes when cultured with fungi, such as Alternaria sp. and Leptosphaeria maculans (1). Previous work examining the epiphytic microbiome of Triticum spp. and Brassica spp. identified strains of Pantoea agglomerans with differential growth antagonism phenotypes when cultured with fungi, such as Alternaria sp. P. agglomerans isolate 4 inhibited the growth of these fungi, while isolate 3 did not exhibit this phenotype.
