Functional Reproductive and Developmental Traits Differences Between Two Macrocystis Ecomorphs: Importance of Neutral Lipids [PDF]

Ecology and Evolution
The kelp genus Macrocystis presents populations recognizable by distinct morphological traits, which has raised discussions on its taxonomical status.

Protein Kinase C Is Likely to be Involved in Zoosporogenesis and Maintenance of Flagellar Motility in the Peronosporomycete Zoospores

Molecular Plant-Microbe Interactions, 2011
The motility of zoospores is critical in the disease cycles of Peronosporomycetes that cause devastating diseases in plants, fishes, vertebrates, and microbes.

Super-resolution imaging of native fluorescent photoreceptors in chytrid fungal eyes [PDF]

The EMBO Journal
Photoorientation in motile fungal zoospores is mediated by rhodopsin guanylyl cyclases (RGCs). In certain chytrids, these photoreceptors form heterodimers consisting of a visible-light-absorbing RGC paired with neorhodopsin (NeoR), a rhodopsin ...

Functional characterization of macrophages and change of Th1/Th2 balance in patients with pythiosis after Pythium insidiosum antigen immunotherapy [PDF]

Scientific Reports
There has been limited research into the role of the Pythium insidiosum antigen (PIA) in modulating immune response in patients with pythiosis. This study investigated the balance of T helper type 2 (Th2) and T helper type 1 (Th1) responses after ...

Molecular mechanism of flagellar motor rotation arrest in bacterial zoospores of Actinoplanes missouriensis before germination [PDF]

Communications Biology
Zoospores of the filamentous actinomycete Actinoplanes missouriensis swim vigorously using flagella and stop swimming to initiate germination in response to nutrient exposure. However, the molecular mechanisms underlying swimming cessation remain unknown.

Which morphological characteristics are most influenced by the host matrix in downy mildews? : A case study in Pseudoperonospora cubensis [PDF]

, 2012
Before the advent of molecular phylogenetics, species concepts in the downy mildews, an economically important group of obligate biotrophic oomycete pathogens, have mostly been based upon host range and morphology.

Neutrophil extracellular traps and phagocytosis in Pythium insidiosum.

PLoS ONE, 2023
Neutrophils are innate immune cells that play crucial roles in response to extracellular pathogens, including bacteria and fungi. Pythium insidiosum (P insidiosum) is a fungus-like pathogen that causes "pythiosis" in mammals.

Changes in Gene Expression in Leaves of Cacao Genotypes Resistant and Susceptible to Phytophthora palmivora Infection

Frontiers in Plant Science, 2022
Black pod rot, caused by Phytophthora palmivora, is a devastating disease of Theobroma cacao L. (cacao) leading to huge losses for farmers and limiting chocolate industry supplies. To understand resistance responses of cacao leaves to P. palmivora, Stage
