Rust fungi are some of the most devastating pathogens crop plants. They obligate biotrophs, which extract nutrients only from living plant tissues and cannot grow apart their hosts. Their lifestyle has slowed dissection molecular mechanisms underlying host invasion avoidance or suppression innate immunity. We sequenced 101-Mb genome Melampsora larici - populina , causal agent poplar leaf rust, 89-Mb Puccinia graminis f. sp. tritici wheat barley stem rust. then compared 16,399 predicted...
The class Dothideomycetes is one of the largest groups fungi with a high level ecological diversity including many plant pathogens infecting broad range hosts. Here, we compare genome features 18 members this class, 6 necrotrophs, 9 (hemi)biotrophs and 3 saprotrophs, to analyze structure, evolution, diverse strategies pathogenesis. most likely evolved from common ancestor more than 280 million years ago. sequences differ dramatically in size due variation repetitive content, but show much...
The genomes of five Cochliobolus heterostrophus strains, two sativus three additional species (Cochliobolus victoriae, carbonum, miyabeanus), and closely related Setosphaeria turcica were sequenced at the Joint Genome Institute (JGI). datasets used to identify SNPs between strains species, unique genomic regions, core secondary metabolism genes, small secreted protein (SSP) candidate effector encoding genes with a view towards pinpointing structural elements gene content associated...
Fusarium head blight (FHB) is primarily caused by graminearum in North America. Isolates of F. can be identified as one three chemotypes: 3-acetyl-deoxynivalenol (3ADON), 15-acetyl-deoxynivalenol (15ADON), and nivalenol (NIV). In this study, we characterized isolates collected 1980 to 2000 (old collection) 2008 (new from Dakota found a 15-fold increase 3ADON the new collection. Evaluation randomly selected 15ADON on spring wheat genotypes (Grandin, Steele-ND, ND 2710) single-floret...
Fusarium crown rot (FCR) is one of the most serious diseases in wheat and causes yield loss health problems (Nellist et al., 2019). Lignin plant tissue exerts a variety functions such as antimicrobial, antiviral, antioxidant anti-cytotoxic (Ralph 2006). Research indicates that dirigent (DIR) proteins are involved synthesis lignin play important roles defence responses (Hosmani 2013; Ralph Wang Fristensky (2001) found DIR protein enhanced resistance to pathogens Rhizoctonia solani...
We used a combination of genomic techniques to monitor chromosomal evolution across hundreds generations as Escherichia coli adapted growth-limiting concentrations either lactulose, methyl-galactoside, or 72:28 mixture the two. DNA microarrays identified 8 unique duplications and 16 deletions among 42 evolvants from 23 chemostat experiments. Each mutation was confirmed by sequencing PCR-amplified flanking and, except for one deletion, an insertion sequence found at break point. vPCR...
Spot blotch, caused by the fungal pathogen Cochliobolus sativus, is an important disease of barley in many production areas world. To assess genetic diversity this pathogen, a worldwide collection C. sativus isolates was evaluated for virulence on and DNA polymorphism. Three pathotypes (0, 1, 2) were identified among 22 tested study 36 characterized previously three differentials (ND5883, Bowman, NDB112) that differ their resistance to sativus. Pathotype 2, which exhibits high cv. only found...
Several species of Metrosideros (Myrtaceae), referred to as ohia in Hawaii, are endemic trees that comprise much 80% the native Hawaiian forests. For centuries, these have provided niches for many indigenous and endangered plants animals treasured by Hawaiians their beauty role folklore legends. During April 2005, a cultivated plant was diagnosed Agricultural Diagnostic Service Center at University Hawaii Manoa infected rust fungus. Rust pustules containing abundant urediniospores were...
The influence of oil composition on the physical properties and antifungal mycotoxin inhibitory activity clove oil-in-water nanoemulsions was investigated. Physically stable could be fabricated by incorporating either ≥75 wt% corn or ≥50 medium chain triacylglycerol (MCT) into before homogenization to prevent Ostwald ripening. with mean diameters <150 nm showed high stability over 30 days storage. physically further evaluated using effective concentration (EC) towards production in two...
The influence of ionic surfactants (cationic surfactant lauric arginate and anionic lysolecithin) on the physical properties, antifungal mycotoxin inhibitory efficacy Tween 80 stabilized cinnamon oil-in-water nanoemulsions was investigated.
ABSTRACT Fusarium crown rot (FCR) and sharp eyespot (SE) are serious soil‐borne diseases in wheat its relatives that have been reported to cause yield losses many areas. In this study, the expression of a cell wall invertase gene, TaCWI‐B1 , was identified be associated with FCR resistance through combination bulk segregant RNA sequencing genome resequencing recombinant inbred line population. Two bi‐parental populations were developed further verify association resistance. Overexpression...
