Summary Arabidopsis thaliana is known to produce the phytoalexin camalexin in response abiotic and biotic stress. Here we studied mechanisms of tolerance fungus Botrytis cinerea , a necrotrophic pathogen A. . Exposure B. induces expression BcatrB an ABC transporter that functions efflux fungitoxic compounds. inoculated on wild‐type plants yields smaller lesions than camalexin‐deficient mutants. A strain lacking functional more sensitive vitro less virulent plants, but still fully...
Perception of pathogen (or microbe)-associated molecular patterns (PAMPs/MAMPs) by pattern recognition receptors (PRRs) is a key component plant innate immunity. The Arabidopsis PRR EF-Tu receptor (EFR) recognizes the bacterial PAMP elongation factor Tu (EF-Tu) and its derived peptide elf18. Previous work revealed that transgenic expression AtEFR in Solanaceae confers elf18 responsiveness broad-spectrum disease resistance. In this study, we developed set bioassays to study activation...
Summary The grapevine ( Vitis ) secondary metabolite resveratrol is considered a phytoalexin, which protects the plant from Botrytis cinerea infection. Laccase activity displayed by fungus assumed to detoxify and facilitate colonization of grape. We initiated functional molecular genetic analysis B. laccases characterizing laccase genes evaluating phenotype targeted gene replacement mutants. Two different were characterized, Bclcc 1 2. Only Bclcc2 was strongly expressed in liquid cultures...
SUMMARY Recent findings are consistent with a slow but constant shift towards reduced sensitivity of Mycosphaerella graminicola to azole fungicides, which target the CYP51 gene. The goal this study was elucidate evolutionary mechanisms through ‐based mutations associated altered have evolved in M. over space and time. To accomplish this, we sequenced compared portion gene encompassing main demethylation inhibitor fungicides. showed an extraordinary dynamic selective haplotype replacement...
Mother plants play an important role in the control of dormancy and dispersal characters their progeny. In Arabidopsis seed is imposed by embryo-surrounding tissues endosperm coat. Here we show that VERNALIZATION5/VIN3-LIKE 3 (VEL3) maintains maternal over progeny establishing epigenetic state central cell primes depth primary later established during maturation. VEL3 colocalises with MSI1 nucleolus associates a histone deacetylase complex. Furthermore, preferentially pericentromeric...
SUMMARY Sterol demethylation inhibitors (DMIs) represent one of the largest groups systemic fungicides that have been used to control agriculturally important fungal pathogens. Knowledge regarding evolution fungicide resistance in agricultural ecosystems is fragmentary and a better understanding processes driving development DMI populations pathogens needed by plant pathologists agrochemical industry. We considered some these using approaches based on molecular population quantitative...
Pattern recognition receptors (PRRs) belonging to the multigene family of receptor-like kinases (RLKs) are sensing devices plants for microbe- or pathogen-associated molecular patterns released from microbial organisms. Here we describe Rnr8 (for Required non-host resistance 8) encoding HvLEMK1, a LRR-malectin domain-containing transmembrane RLK that mediates barley non-adapted wheat powdery mildew fungus Blumeria graminis f.sp. tritici. Transgenic lines with silenced HvLEMK1 allow entry and...
Agricultural soil harbors a diverse microbiome that can form beneficial relationships with plants, including the inhibition of plant pathogens. Pseudomonas spp. are one most abundant bacterial genera in and rhizosphere play important roles promoting health. However, genetic determinants this activity only partially understood. Here, we genetically phenotypically characterize fluorescens population commercial potato field, where identify strong correlations between specialized metabolite...
Leaf rust, caused by the foliar pathogen
Nonhost resistance (NHR) protects plants against a vast number of non-adapted pathogens which implicates potential exploitation as source for novel disease strategies. Aiming at fundamental understanding NHR global analysis transcriptome reprogramming in the economically important Triticeae cereals wheat and barley, comparing host nonhost interactions three major fungal pathosystems responsible powdery mildew (Blumeria graminis ff. ssp.), cereal blast (Magnaporthe sp.) leaf rust (Puccinia...
Eighty‐eight Australian and 10 international barley cultivars were assessed for resistance to the stripe (yellow) rust pathogen, Puccinia striiformis f. sp. hordei (Psh). All tested seedling two UK ‐derived isolates of Psh (11.01 83.39) that shown differ in virulence based on responses 16 differential genotypes. The 98 differed substantially response; 45% susceptible 11.01, 53% 83.39 44% both isolates. observed diverse infection types ( IT s) suggest presence known uncharacterized...
