Genome-wide prediction and functional validation of promoter motifs regulating gene expression in spore and infection stages of Phytophthora infestans. [PDF]

open access: yesPLoS Pathogens, 2013
Most eukaryotic pathogens have complex life cycles in which gene expression networks orchestrate the formation of cells specialized for dissemination or host colonization.

Zoosporogênese in vitro entre isolados do oomiceto Pythium insidiosum In vitro zoosporogenesis among oomycetes Pythium insidiosum isolates

open access: yesCiência Rural, 2008
Pythium insidiosum é um oomiceto aquático, responsável pela etiologia da pitiose, uma enfermidade crônica, observada freqüentemente em eqüinos. A produção de zoósporos móveis por este microrganismo se constitui no fator determinante da ocorrência da ...

A method to obtain rapid zoosporogenesis of Pythium insidiosum

open access: yesMycopathologia, 1988
Nine strains of Pythium insidiosum the etiologic agent of pythiosis, were inoculated on 2% water agar plus grass blades and then incubated one day at 25 degrees C, 35 degrees C and 37 degrees C. Sporangium and secondary biflagellate-type zoosporas from the parasitized grass blades were noticed in induction medium after one hour of incubation at 35 ...

Chitosan biostimulant controls infection of cucumber by Phytophthora capsici through suppression of asexual reproduction of the pathogen

open access: yesActa Agrobotanica, 2019
The biopolymer chitosan is a derivative of chitin, which can promote plant growth and protect plants from phytopathogens. This study aimed to evaluate the efficacy of chitosan as a biostimulant and a biorational agent to protect cucumber plants from ...

Ultrastructural studies on zoosporogenesis of Halopteris filicina (Sphacelariales, Phaeophyta)

open access: yesPhycologia, 1986
Abstract The development of the unilocular sporangia of Halopteris filicina (Phaeophyta) commences with the formation of the reproductive branchlets, the apical cells of which differentiate into spore mother cells. Afterwards, meiosis occurs, which becomes evident by the formation of typical synaptonemal complexes.

A Mating-Induced Protein of Phytophthora infestans Is a Member of a Family of Elicitors with Divergent Structures and Stage-Specific Patterns of Expression

open access: yesMolecular Plant-Microbe Interactions, 2003
Five members of an elicitor-like gene family from Phytophthora infestans were examined. The family was identified through the analysis of M81, a mating-induced gene. The predicted M81 product resembled a 42-kDa P.

Multiple Pathways Regulate the Induction of Genes During Zoosporogenesis in Phytophthora infestans [PDF]

open access: yesMolecular Plant-Microbe Interactions®, 2004
Zoospores are a critical component of the disease cycles of most oomycete pathogens. To better understand this stage, genes induced during zoosporogenesis were identified from Phytophthora infestans, the potato late blight pathogen. Using cDNA arrays representing 2,600 genes expressed during zoosporogenesis, 69 genes showing >fourfold increases in ...

Aspectos clínicos, morfológicos e imuno-histoquímicos da pitiose gastrintestinal canina

open access: yesPesquisa Veterinária Brasileira, 2009
Através de um estudo retrospectivo dos casos de biópsias e necropsias de cães recebidos no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria, constatou-se a ocorrência de dois casos confirmados e de quatro casos suspeitos de ...

Gene Expression Profiling During Asexual Development of the Late Blight Pathogen Phytophthora infestans Reveals a Highly Dynamic Transcriptome

open access: yesMolecular Plant-Microbe Interactions, 2008
Much of the pathogenic success of Phytophthora infestans, the potato and tomato late blight agent, relies on its ability to generate from mycelia large amounts of sporangia, which release zoospores that encyst and form infection structures.

New role for Cdc14 phosphatase: localization to basal bodies in the oomycete phytophthora and its evolutionary coinheritance with eukaryotic flagella.

open access: yesPLoS ONE, 2011
Cdc14 protein phosphatases are well known for regulating the eukaryotic cell cycle, particularly during mitosis. Here we reveal a distinctly new role for Cdc14 based on studies of the microbial eukaryote Phytophthora infestans, the Irish potato famine ...
