TL;DR: This work analyzed the structures of the seed microbiotas of different plants from the family Brassicaceae and their dynamics during germination and emergence through sequencing of three molecular markers: the ITS1 region of the fungal internal transcribed spacer, the V4 region of 16S rRNA gene, and a species-specific bacterial marker based on a fragment of gyrB.
Journal ArticleDOI
Methods for Observing Microbial Biofilms Directly on Leaf Surfaces and Recovering Them for Isolation of Culturable Microorganisms
TL;DR: The epifluorescence techniques described here can be used to rapidly determine the abundance and localization of biofilms on leaves and to disintegrate them for isolation of the culturable microorganisms they contained.
Journal ArticleDOI
Ecological patterns of seed microbiome diversity, transmission, and assembly.
TL;DR: The purpose of this mini-review is to provide an overview of current knowledge on the diversity, structure and role of the seed microbiota.
Journal ArticleDOI
The complete genome sequence of Xanthomonas albilineans provides new insights into the reductive genome evolution of the xylem-limited Xanthomonadaceae

TL;DR: The two xylem-limited Xanthomonadaceae, during their descent from a common ancestral parent, experienced a convergent reductive genome evolution, Adaptation to the nutrient-poor Xylem elements and to the cloistered environmental niche of xylesm vessels probably favoured this convergent evolution.
Journal ArticleDOI

TL;DR: The interest of this image analysis procedure for assessing the levels of quantitative resistance is illustrated with the quantitation of disease severity on five commercial varieties of bean inoculated with Xff CFBP4834-R.
