Intraspecific Variation and Recent Loss of Ancient, Conserved Effector Genes in the Sudden Oak Death Pathogen Phytophthora ramorum

open access: yesMolecular Plant-Microbe Interactions
Members of the Phytophthora genus are responsible for many important diseases in agricultural and natural ecosystems. Phytophthora ramorum causes devastating diseases of oak and tanoak stands in U.S. forests and larch in the United Kingdom.

Activity Against Pythium insidiosum and Isolated Constituents of Cordia insignis Roots

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the roots of Cordia insignis in search of novel treatments for pythiosis, caused by the oomycete Pythium insidiosum. Seven compounds are isolated, including steroids, a saponin, a coumarin, a fatty acid, and a glycoside, the latter two are reported for the first time in the genus.

The life cycles of cryptogams [PDF]

open access: yes, 1991
Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Exploiting Paraphaeosphaeria minitans and Its Antifungal Metabolites as Bio‐Fungicides for Eco‐Friendly Management of Head Rot Disease in Cabbage

open access: yesMicrobial Biotechnology, Volume 19, Issue 2, February 2026.
Biocontrol of Cabbage Head Rot: Paraphaeosphaeria minitans produces antifungal metabolites, disrupts sclerotia of Sclerotinia sclerotiorum, and reduces disease incidence in cabbage under field conditions. ABSTRACT Cabbage head rot, caused by Sclerotinia sclerotiorum, threatens crop yield and quality.

Indigenous peoples and local community reports of climate change impacts on biodiversity

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.
