Molecular basis of plant cell death suppression by the phytophthora infestans effector AVR3a
… defense and to colonize their host. INF1 is a P. infestans elicitin with features of PAMPs that requires the co-regulator receptor-like kinase SERK3/BAK1 to trigger cell death. AVR3a is an effector translocated by P. infestans that suppresses INF1-triggered cell death (ICD). However, the potato …

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 …

Investigation of the recognition and host target of the Phytophthora infestans effector PiAVR2
… thesis was to determine the host target of the Phytophthora infestans effector PiAVR2 and the means by which this avirulence protein is recognised by the potato resistance protein, R2. Prior to this PhD, forward genetic studies identified three RXLR effector encoding genes within the AVR2 locus. …

Secretion and delivery of virulence proteins from <i>Phytophthora infestans</i> to its host
… a ravaging disease caused by the oomycete Phytophthora infestans, is a major threat to global food security. P. infestans secretes effector proteins that are delivered inside (cytoplasmic effector) or outside (apoplastic effector) plant cells to neutralise host immunity. One of the most …

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 …

The changing <em>Phytophthora infestans</em> population: implications for late blight epidemics and control
<p><em>Phytophthora 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 …

Diagnostics and epidemiology of <i>Phytophthora infestans</i> : the cause of late blight of potato
… and sensitive PCR assay for the detection 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 …

Modelagem de tendências espaciais na seleção de linhagens de tomateiro resistentes à Phytophthora infestans (Mont.) de Bary
… as linhagens de tomateiro mais resistentes à Phytophthora infestans. Para isso, 71 linhagens de introgressão de Solanum pennellii foram avaliadas quanto a essa característica em campo, com inoculação artificial, em ensaio com testemunhas intercalares. As testemunhas utilizadas foram as …

An investigation of gene expression, alternative splicing and nonsense-mediated decay in potato in response to Phytophthora infestans infection
… AS and NMD in the interaction between potato and Phytophthora infestans by focusing on post-transcriptional regulation and particularly NB-LRR genes. An in silico analysis of current potato genome and transcriptome databases (Phytozome and SpudDB) showed that some NB-LRR genes are potentially …

Investigation into the function of Pi17316, a novel effector protein from <i>Phytophthora infestans</i> that compromises plant immunity
… is secreted by the potato late blight pathogen, Phytophthora infestans, to target a host MAP3K, VIK. Inside the plant cell Pi17316 localises to the plasma membrane, where it interacts with VIK in order to suppress the INF1 and R2/Avr2 cell death pathways and to enhance P. infestans colonisation. …

Caractérisation moléculaire de la spécificité d'organe chez Phytophthora infestans, agent causal du middiou de la pomme de terre
… plus dévastatrices est le mildiou, causée par Phytophthora infestans. Alors que plusieurs gènes Avr ont été identifiés chez P. infestans, la majorité des connaissances acquises à l'aide de ceux-ci a été obtenue au niveau de l'infection du feuillage. Pourtant, P. infestans s'attaque …

Exploiting crosstalk between growth and immunity in plants : the role of the <i>Phytophthora infestans</i> effector AVR2 in potato late blight
… such effector, secreted by the oomycete pathogen Phytophthora 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 …

Gene prediction with conditional random fields
… The extensions were tested on the genomes of Phytophthora infestans, Culex pipiens, and Homo sapiens. The gene predictions were analyzed and the benefits of discriminative methods were explored.
