First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

Foliar Treatments of 2,4‐Dichlorophenoxyacetic Acid for Control of Common Scab in Potato Have Beneficial Effects on Powdery Scab Control

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Prior studies have shown that applications of the synthetic auxin 2,4‐dichlorophenoxyacetic acid (2,4‐D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4‐D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab.

Soil biome variation of Lupinus nipomensis in wet‐cool vs. dry‐warm microhabitats and greenhouse

American Journal of Botany, Volume 112, Issue 4, April 2025.
Abstract Premise Environmental DNA (eDNA) can be used to determine the composition of the soil biome community, revealing beneficial and antagonistic microbes and invertebrates associated with plants. eDNA analyses can complement traditional soil community studies, offering more comprehensive information for conservation practitioners. Studies are also

Occurrence of Potato Powdery Scab Caused by Spongospora subterranea in Korea [PDF]

The Plant Pathology Journal, 2003
Potato tubers with scab lesions were found in several regions of Gangwon province in Korea during disease surveys in 2000 and 2001. The lesions appeared as shallow scabs with torn and raised skin around the periphery of the lesion. Sometimes the lesions expanded on tuber surface and formed hollowed-out areas.
