Plant pathogen arms race
WebDec 21, 2024 · IV. Evolutionary signature of plant–pathogen interactions. How do coevolutionary processes influence the evolution of host immunity at the molecular level? Frequency-dependent selection and arms race dynamics are expected to result in different patterns of polymorphisms (Woolhouse et al., 2002). Negative frequency-dependent … Plants have evolved sophisticated immune systems to defend themselves against disease-causing microbes, or pathogens1,2, that can cause them serious damage. Plant intracellular immune receptor proteins called nucleotide-binding, leucine-rich repeat (NLR) proteins activate immune defences when they detect … See more The pepper Capsicum chinense has an NLR immune receptor called Tsw. This NLR recognizes the protein effector NSs, which is encoded by the pathogen Tomato spotted wilt virus (TSWV) — a cause of serious crop losses … See more TCP21, a common repressor of plant hormone signalling, was previously unknown. From the pathogen’s perspective, targeting … See more After we found that the leucine-rich repeat (LRR) domain of the plant protein Tsw is structurally similar to those of the proteins COI1, TIR1 and MAX2, we hypothesized that viral NSs might directly target these hormone receptors. … See more

WebThe arms race between plants and pathogens is a complex process. To dissect the plant defense and pathogen virulence responses simultaneously, we used sorghum and Xantho-monas vasicola pv. holcicola, as a model pathosystem. We performed dual RNA-seq on infected sorghum with a range of disease phenotypes. Our characterization of this WebAug 1, 2024 · The natural diversity of pathogen effectors and host immune components represents a snapshot of the underlying evolutionary processes driving the host-pathogen arms race. In plants, this arms race is manifested by an ongoing cycle of disease and resistance driven by pathogenic effectors that promote disease (effector-triggered …
Web1 day ago · Phytopathogenic fungi secretes a range of effectors to manipulate plant defenses. Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) is a soil-borne pathogen that causes destructive banana wilt disease. Understanding the molecular mechanisms behind Foc TR4 effectors and their regulation of pathogenicity is helpful for … WebJan 5, 1999 · Alternative hypotheses for the course of coevolution include: (i) escalating arms races in which plants relentlessly add to their chemical arsenals, whereas …
WebABSTRACT. The evolutionary plant-pathogen arms race has equipped plants with the immune system that can defend against pathogens. Pattern-triggered immunity and effector-triggered immunity are two major branches of innate immunity that share immune responses, including oxidative bursts, transcriptional reprogramming, and cell wall … WebOct 30, 2007 · Abstract. Plants recognize pathogens through immune-like receptors, which activate a resistance response. In turn, pathogens have evolved means to modify plant …
WebAug 1, 2000 · Arms races are ultimately determined at the phenotypic level, but examining individual antagonistic genetic systems, such as resistance (R) genes and their corresponding avirulence (Avr) genes, and cell-wall attacking enzymes and their inhibitors, can provide new insights.
