Phagocytosis underpins the biotrophic lifestyle of intracellular parasites in the class Phytomyxea (Rhizaria). [PDF]
New Phytol, 2023 Summary Phytomyxea are intracellular biotrophic parasites infecting plants and stramenopiles, including the agriculturally impactful Plasmodiophora brassicae and the brown seaweed pathogen Maullinia ectocarpii. They belong to the clade Rhizaria, where phagotrophy is the main mode of nutrition.

Regulation of Oomycete Autophagy, Lipid Droplet Accumulation and Pathogenesis by Three Rab GTPases. [PDF]
Mol Plant PatholPlRab6– PlRab8A complex controls growth, virulence and autophagy, while PlRab8B modulates sporulation and virulence via autophagy and LD metabolism in P. litchii. ABSTRACT Among eukaryotes, Rab GTPases are critical for intracellular membrane trafficking and possess various functions.

A CRISPR/Cas9-mediated in situ complementation method for Phytophthora sojae mutants. [PDF]
Mol Plant Pathol, 2021 A regulatory B‐subunit of protein phosphatase 2A was used to demonstrate an in situ complementation method of a mutated gene in Phytophthora sojae, verifying its roles in hyphal growth, soybean infection, and sporangia production. Abstract Phytophthora sojae is an important model species for oomycete functional genomics research.

New Phytologist, Volume 235, Issue 2, Page 718-731, July 2022., 2022 Summary Clade II basic helix–loop–helix transcription factors (bHLH TFs) are essential for pollen production and tapetal nursing functions in angiosperm anthers. As pollen has been suggested to be related to bryophyte spores by descent, we characterized two Physcomitrium (Physcomitrella) patens clade II bHLH TFs (PpbHLH092 and PpbHLH098), to test if ...

Ecology and Evolution, Volume 11, Issue 10, Page 5484-5496, May 2021., 2021 We analyzed nucleotide characteristics of eukaryotic translation elongation factor‐1α (eEF‐lα) gene from 165 Phytophthora infestans isolates and the physical and chemical properties of its derived proteins. Our results indicate that post‐translation modifications may function synergistically with nucleotide codes to regulate the adaptive landscape of ...

A Cryptic Alternative for the Evolution of Hyphae
BioEssays, Volume 42, Issue 6, June 2020., 2020 The current view that hyphae evolved about 400 million years ago when plants and fungi colonized land is challenged. Recent recognition of a deep biosphere fossil record provides an alternative view on hyphae: one where the fundamental functions of hyphae developed in ancient cryptic habitats and already where adapted for a terrestrial life‐style when ...

Molecular Plant Pathology, Volume 21, Issue 4, Page 460-474, April 2020., 2020 PiCAT2 is required for P. infestans asexual reproduction, abiotic stress tolerance, and pathogenicity; reducing or elevating catalase activity suppresses sporangia formation, germination, and appressoria formation. Abstract Catalase is present in prokaryotic and eukaryotic organisms and is important for the protective effects of the antioxidant system ...

Advances in Agriculture, Volume 2020, Issue 1, 2020., 2020 Pepper (Piper nigrum L.) serves as a source of income to smallholder spice farmers in Morogoro district of Tanzania. Recently, spike shedding and stem wilting of pepper plants were reported to cause about 30% yield loss of the crop. This study was undertaken to identify the causal agent(s) of the problems.
