Engineering durable late blight resistance to protect solanaceous plants
… the oomycete pathogen responsible for late blight of potato and tomato, is regarded as the biggest threat to global potato production and is thought to cost the industry around £6 billion annually. Traditionally, fungicides have been used to control the disease, but this is both …

STRUCTURE-FUNCTION STUDIES OF TRANSLOCATED EFFECTORS FROM THE LATE BLIGHT PATHOGEN
… inside host cells. These effectors manipulate host processes for the pathogen’s benefit. However, in response to this manipulation, plants have evolved to monitor for effectors and trigger defence responses. Amongst plant pathogens, oomycetes of the genus Phytophthora have arguably caused …

The changing <em>Phytophthora infestans</em> population: implications for late blight epidemics and control
… infestans</em>, the causal agent of potato late blight, causes millions of pounds of losses worldwide each year. Within the UK P. <em>infestans </em>populations there has been a dramatic increase in the proportion of the A2 mating type due to genotype 13_A2 and concerns have been raised …

Diagnostics and epidemiology of <i>Phytophthora infestans</i> : the cause of late blight of potato
… of <i>Phytophthora infestans</i>, the cause of late blight of potato, in soil and plant tissues was developed. A <i>P. infestans</i> specific primer pair (INF FW2 and INF REV) was designed by comparing the aligned sequences of internal transcribed spacer regions (ITS) of a range of …

Development and Implementation of a New National Warning System for Potato Late Blight in Great Britain
… infestans (Mont) De Bary, the cause of potato late blight, is arguably the most important species of the genus Phytophthora in terms of economic losses and the cost of fungicides used for its control. The Smith Period is a set of temperature and humidity criteria that comprise the national …

Exploiting crosstalk between growth and immunity in plants : the role of the <i>Phytophthora infestans</i> effector AVR2 in potato late blight
… infestans; the pathogen responsible for potato late blight. AVR2 interacts with a family of kelch-repeat containing phosphatases in potato, the BSLs, implicated in brassinosteroid pathway signalling – a major hormone signalling pathway in plants associated with growth and development. This work …

Identification of new functional resistance genes against <i>P. infestans </i>in <i>Solanaceae</i> species
… The probe library was successfully used to map a late blight resistance in the diploid potato population B3C1HP. Using bulked-segregant resistance gene enrichment and sequencing (RenSeq) analysis in this population, which segregated 1:1 for the phenotype, the resistance was mapped to the lower end …

An Economic Impact Assessment of Cooperation-88 Potato Variety in China
Cooperation-88 (C88) is a late blight resistant potato variety that was formally released in China in 2001 and has become popular in China's Yunnan Province. The International Potato Center (CIP) and Yunnan Normal University collaborated to produce the variety, which is one of CIP's most successful …

Approaches towards disease resistance to filamentous pathogens
… the growth of two Phytophthora species, the late-blight pathogen P. infestans and the vegetable pathogen P. capsici. The differential effect of capsidiol towards these two oomycetes was determined and quantified. I also monitored intraspecific variation among various P. infestans isolates in …

Investigation into the function of Pi17316, a novel effector protein from <i>Phytophthora infestans</i> that compromises plant immunity
… are exemplified by pathogen effectors that manipulate processes inside the host cell to benefit colonisation. Knowledge of how these effectors and their targets function is crucial to develop strategies to enhance crop resistance. This project focuses on one such effector, Pi17316, which is …

Investigation of the recognition and host target of the Phytophthora infestans effector PiAVR2
… PiAVR2, named PiAVR2-like, was found within isolates of P. infestans. Isolates which only express PiAVR2-like are virulent on potato cultivars expressing R2. Isolates which express both forms, or only the PiAVR2 form, are avirulent on cultivars expressing R2. This suggests that expressing only …

NOVEL PERSPECTIVES IN THE CONTROL OF PLANT PATHOGENIC OOMYCETES
… oomycete-borne diseases such as potato late blight, blight and fruit rot of cucurbits, Phytium root rot and grapevine downy mildew. Out of the 77 compounds tested, two promising molecules showed a consistently high efficacy and were characterized for their antimicrobial activity and mode …

CHARACTERIZATION OF BIOACTIVE PEPTIDES IDENTIFIED FROM GENETICALLY ENCODED LIBRARIES.
… demonstrating that the library can be used to isolate bioactive molecules. After validation, 14 cell wall biosynthetic enzymes have been selected and screened with CYCLIC to identify CPs having the ability to interfere with the activity of these target proteins and, consequently, with the cell …

Effects of Cucumber Mosaic Virus on Plant-Pollinator Relationships
… seed production of CMV-infected and mock-inoculated tomato plants. In the 2018 field season, after growth and inoculation of tomato plants (either with CMV or sterile water for mock-inoculation) the plants were placed outside in twelve plots each plot consisting of twelve plants of either …

A functional study of the<em> Phytophthora infestans</em> Avr3a alleles and paralogs
Late Blight disease, caused by Phytophthora infestans, is the most significant threat to potato production world-wide. Identifying and deploying more durable host resistance to P. infestans is a promising way forward to sustain the production of potato. To achieve this goal, it is important to seek …

Evaluation of soybean cyst nematode (SCN) resistance in perennial glycine species and genome-wide association mapping and genomic prediction study for SCN resistance in common bean and prediction of the short distance movement of soybean rust urediniospores through machine learning
… activities. From the famine caused by potato late blight (Phytophthora infestans) in Ireland in 1846, to the dramatic economic loss caused by downy mildew of grapes (Plasmopara viticola) in the Mediterranean in 1865, to the loss of the valuable banana cultivar ‘Gros Michel’ caused by Fusarium …

Transcriptomic studies of the early stages of potato infection by <i>Phytophthora infestans</i>
The late blight pathogen, Phytophthora infestans, is the most destructive pathogen of its solanaceous hosts potato and tomato. It is a threat to global food security and it is therefore important to understand the cellular and molecular dynamics underlying colonisation of its host plants. This …

An investigation of gene expression, alternative splicing and nonsense-mediated decay in potato in response to Phytophthora infestans infection
… 60% of plant genes and is enriched in stress related genes, such as NB-LRR and receptor-like kinase genes. AS is also associated with mRNA stability through the activation of the nonsense-mediated decay (NMD) pathway; a conserved RNA surveillance mechanism. NMD targets aberrant endogenous …
