Evolution of linked avirulence effectors in Leptosphaeria maculans is affected by genomic environment and exposure to resistance genes in host plants. [PDF]

PLoS Pathogens, 2010
Brassica napus (canola) cultivars and isolates of the blackleg fungus, Leptosphaeria maculans interact in a 'gene for gene' manner whereby plant resistance (R) genes are complementary to pathogen avirulence (Avr) genes.

Avirulence Gene AVR-Pita1 in the Rice Blast Fungus

Research in Plant Disease, 2019
The rice blast fungus, Magnaporthe oryzae, is one of the most economically important crop diseases. In addition, rice-M. oryzae interaction is a classical gene-for-gene host-pathogen system.

Molecular Population Genetic Analysis Differentiates Two Virulence Mechanisms of the Fungal Avirulence Gene NIP1

Molecular Plant-Microbe Interactions, 2004
Deletion or alteration of an avirulence gene are two mechanisms that allow pathogens to escape recognition mediated by the corresponding resistance gene in the host. We studied these two mechanisms for the NIP1 avirulence gene in field populations of the

Remarkable recent changes in the genetic diversity of the avirulence gene AvrStb6 in global populations of the wheat pathogen Zymoseptoria tritici. [PDF]

Mol Plant Pathol, 2021
Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is one of the most economically important diseases of wheat. Recently, both factors of a gene-for-gene interaction between Z. tritici and wheat, the wheat receptor-like kinase Stb6

Genomics accelerated isolation of a new stem rust avirulence gene - wheat resistance gene pair [PDF]

, 2021
Stem rust caused by the fungus Puccinia graminis f. sp. tritici (Pgt) is a devastating disease of the global staple crop wheat. Although this disease was largely controlled by genetic resistance in the latter half of the 20th century, new strains of Pgt ...

Molecular mechanisms of Phytophthora sojae avirulence effectors escaping host recognition

Frontiers in Microbiology, 2023
Phytophthora sojae is a well-known destructive oomycete pathogen, which causes soybean stem and root rot and poses a serious threat to global food security. Growing soybean cultivars with the appropriate resistance to P. sojae (Rps) genes are the primary

Loss of PWT7, Located on a Supernumerary Chromosome, Is Associated with Parasitic Specialization of Pyricularia oryzae on Wheat

Molecular Plant-Microbe Interactions, 2023
Pyricularia oryzae, a blast fungus of gramineous plants, is composed of various host genus–specific pathotypes. The avirulence of an Avena isolate on wheat is conditioned by PWT3 and PWT4.

Avoidance of Host Recognition by Alterations in the Repetitive and C-Terminal Regions of AvrXa7, a Type III Effector of Xanthomonas oryzae pv. oryzae

Molecular Plant-Microbe Interactions, 2005
avrXa7 is a member of the avrBs3/pthA gene family. The gene is a critical type III effector in several strains of Xanthomonas oryzae pv. oryzae (virulence activity), and in the presence of the Xa7 host gene for resistance, controls the elicitation of ...

Correlation of Genomic Compartments with Contrastive Modes of Functional Losses of Host Specificity Determinants During Pathotype Differentiation in Pyricularia oryzae

Molecular Plant-Microbe Interactions, 2021
The specificity between pathotypes of Pyricularia oryzae and genera of gramineous plants is governed by gene-for-gene interactions. Here, we show that avirulence genes involved in this host specificity have undergone different modes of functional losses ...
