Tolerance Against Co‐Infection of Two Partitiviruses and Ourmia‐Likevirus Is Common Among Heterobasidion annosum Strains on Artificial Media and in Dead Wood

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Some mycoviruses cause hypovirulence in fungi, but the effects often vary among different host strains. Heterobasidion partitiviruses 13‐an1 and 15‐pa1 (HetPV13‐an1 and HetPV15‐pa1) have been associated with strain‐specific and variable hypovirulence of Heterobasidion annosum, but variation in phenotypic effects of HetPV15‐pa1 or the ...

Review of the biology and management of large patch of warm‐season turfgrasses

Crop Science, Volume 65, Issue 2, March/April 2025.
Abstract Large patch (Rhizoctonia solani Kühn: anastomosis group [AG] 2‐2) is a destructive disease in warm‐season turfgrasses worldwide, particularly zoysiagrass (Zoysia spp.). Developing as an orange or tan color, the disease starts as small, round patches that can eventually progress to several meters in diameter.

Viroid and viroid‐like elements in plants and plant‐associated microbiota: a new layer of biodiversity for plant holobionts

New Phytologist, Volume 244, Issue 4, Page 1216-1222, November 2024.
Summary The functional relevance of plant‐associated microorganisms is theoretically framed within the holobiont concept. The role of viruses in plant holobionts is being recognized both for their direct effects when hosted in plants (cryptic plant viruses) and for their indirect effects when infecting microorganisms associated with plants in ...
