Plant diseases are an important threat to food production. While major pathogenicity determinants required for disease have been extensively studied, less is known on how pathogens thrive during host colonization, especially at early infection stages. Here, we used randomly barcoded-transposon insertion site sequencing (RB-TnSeq) perform a genome-wide screen and identify key bacterial fitness of the vascular pathogen Xanthomonas campestris pv (Xcc) cauliflower plant (Brassica oleracea). This...
Peronospora effusa causes downy mildew, the economically most important disease of cultivated spinach worldwide. To date, 19 P. races have been denominated based on their capacity to break resistances, but genetic diversity and evolutionary processes that contribute race emergence are unknown. Here, we performed first systematic analysis showing those emerge by both asexual sexual reproduction. Specifically, studied 26 isolates from 16 mitochondrial nuclear comparative genomics....
SUMMARY Genetic screens are powerful tools for biological research and one of the reasons success thale cress Arabidopsis thaliana as a model. Here, we describe whole‐genome sequencing 871 lines from Homozygous EMS Mutant (HEM) collection novel resource forward reverse genetics. With an average 576 high‐confidence mutations per HEM line, over three independent altering protein sequences found on gene in collection. Pilot genetics experiments reproductive, developmental, immune physiological...
Bacteria of the genus Xanthomonas cause economically significant diseases in various crops. Their virulence is dependent on translocation type III effectors (T3Es) into plant cells by secretion system (T3SS), a process regulated master response regulator HrpG. Although HrpG has been studied for over two decades, its regulon across diverse species, particularly beyond secretion, remains understudied.
Fire blight represents a widespread disease in Lilium spp. and is caused by the necrotrophic Ascomycete Botrytis elliptica . There are >100 species that fall into distinct phylogenetic groups these have been used to generate contemporary commercial genotypes. It known among lily breeders growers different of lilies differ susceptibility fire blight, but genetic basis mechanisms unresolved. The aim this study was quantify differences between plant genotypes virulence fungal isolates....

Bacteria use various motility mechanisms to explore their environments. Chemotaxis is the ability of a motile bacterial cell direct its movement in response chemical gradients. A number methods have been developed and widely used study chemotactic responses chemoeffectors including capillary, agar plug, microscopic slide, microfluidic assays. While valuable, these assays are primarily designed monitor rapid on small scale, which poses challenges collecting large quantities attracted...
