The maize Hm2 gene provides protection against the leaf spot and ear mold disease caused by Cochliobolus carbonum race 1 (CCR1). In this regard, it is similar to Hm1, the better-known disease resistance gene of the maize-CCR1 pathosystem. However, in contrast to Hm1, which provides completely dominant resistance at all stages of plant development, Hm2-conferred resistance is only partially dominant and becomes fully effective only at maturity. To investigate why Hm2 behaves in this manner, we… Expand
Adult Plant Resistance in Maize to Northern Leaf Spot Is a Feature of Partial Loss-of-function Alleles of Hm1
TLDR
Using a combination of molecular genetics, biochemistry and physiology, multiple lines of evidence are presented that demonstrate that APR is a feature or symptom of weak forms of resistance. Expand
Adult plant resistance in maize to northern leaf spot is a feature of partial loss-of-function alleles of Hm1
TLDR
A link between the energetic or metabolic status of the host and disease resistance affected by HC-toxin catabolism by the APR alleles of HCTR is demonstrated, demonstrating the susceptibility of seedlings derives from a greater need for H CTR activity, not reduced accumulation of the gene product. Expand
A guardian of grasses: Specific origin and conservation of a unique disease-resistance gene in the grass lineage
TLDR
Phylogenetic analysis indicated that Hm1 evolved exclusively and early in the grass lineage, implying that the evolution and/or geographical distribution of grasses may have been constrained if Hm2 did not emerge. Expand
Changes in disease resistance phenotypes associated with plant physiological age are not caused by variation in R gene transcript abundance.
TLDR
Consistent transcript levels in plants of different physiological ages with variable levels of disease resistance demonstrate that changes in disease-resistance phenotypes associated with plant age cannot be attributed to changes in R-gene transcript abundance. Expand
Characterization and fine-mapping of a resistance locus for northern leaf blight in maize bin 8.06
TLDR
Allelism analysis suggested that qNLB8.06DK888 confers race-specific resistance exclusively to NLB, and three compelling candidate genes were identified in this region. Expand
Structure-Based Computational Study of Two Disease Resistance Gene Homologues (Hm1 and Hm2) in Maize (Zea mays L.) with Implications in Plant-Pathogen Interactions
TLDR
This study is the first in silico attempt to unravel the biophysical and biochemical basis of cofactor recognition in enzymatic class of R genes in cereal crop maize. Expand
The plant genetic background affects the efficiency of the pepper major nematode resistance genes Me1 and Me3
TLDR
The results highlight the primary importance of the choice of both the R-gene and the genetic background into which it is introgressed during the selection of new elite cultivars by plant breeders. Expand
Potato Tuber Blight Resistance Phenotypes Correlate with RB Transgene Transcript Levels in an Age-Dependent Manner.
TLDR
The results indicate that the presence of the transgene RB has a positive yet only marginally significant effect on tuber disease resistance, and suggest that organ-specific resistance might result directly from transcriptional regulation of the resistance gene itself. Expand
Insights into the structure-function relationship of disease resistance protein HCTR in maize (Zea mays L.): a computational structural biology approach.
TLDR
Comparative modelling, molecular dynamics simulation and docking studies are reported to explain the structure-function relationship and the mode of cofactor (NADPH) binding in HCTR enzyme at the molecular level and to pave the way for exploration of similar genes in other economically important crop varieties. Expand
Fungal-induced protein hyperacetylation in maize identified by acetylome profiling
TLDR
Investigation of how the effector molecule HC-toxin (HCT), a histone deacetylase inhibitor produced by the fungal pathogen Cochliobolus carbonum race 1, promotes virulence in maize through altering protein acetylation demonstrates that acetylations is a widespread posttranslational modification impacting proteins encoded by many intensively studied maize genes.

Plant-pathogen microevolution: molecular basis for the origin of a fungal disease in maize.
TLDR
It is demonstrated that resistance to C. carbonum race 1 is the wild-type condition in maize, and results suggest that the Hm-encoded resistance is of ancient origin and probably is conserved in all grasses. Expand

TLDR
Gene-dosage experiments and segregation patterns indicate that adult susceptibility in Ws-0 is incomepletely dominant to adult resistance in Col-0, and genetic mapping in a Col x Ws F2 population revealed a major locus on the bottom arm of chromosome 5, which is named RPP31. Expand

A Biochemical Phenotype for a Disease Resistance Gene of Maize.
TLDR
It is reported that detoxification of HC-toxin is the biochemical basis of Hm-specific resistance of maize to infection by C. carbonum race 1, and that this enzyme activity is detectable only in extracts of maize that are resistant to the fungus. Expand
Short communication: developmental control of Xa21-mediated disease resistance in rice.
TLDR
It is found that Xa 21 expression is independent of plant developmental stage, infection with Xoo, or wounding, indicating that the developmental regulation of Xa21-resistance is either controlled post-transcriptionally or by other factors. Expand
Developmental regulation of Mi-mediated aphid resistance is independent of Mi-1.2 transcript levels.
TLDR
It is demonstrated that Mi-1.2 transcript levels do not modulate the degree of aphid resistance in tomato leaves, or control the differences in regulation between aphid and nematode resistance. Expand

Evidence is presented suggesting that the RPP genes at this locus are subject to the same selective forces that have been demonstrated for structurally different LRR-type R genes. Expand
Developmental control of promoter activity is not responsible for mature onset of Cf-9B-mediated resistance to leaf mold in tomato.
TLDR
Fungal inoculation of tomato plants containing reciprocal Cf-9/Cf-9B promoter-coding region swaps, analysis of Tomato plants containing promoter-gusA fusions, and a reverse transcriptase-polymerase chain reaction study of Cf- 9 and Cf-8B transcripts in tomato plants suggested that transcriptional control of Cf -9B did not account for the late onset of Cf.9B-mediated resistance.

TLDR
It is found that the dominant Corngrass1 mutant of maize encodes two tandem miR156 genes that are overexpressed in the meristem and lateral organs, providing a mechanism for how species-level heterochronic changes can occur in nature. Expand
