The ankyrin repeat-containing protein PlANK1 mediates mycelial growth, oospore development, and virulence in Peronophythora litchii

Phytopathology Research, 2023
Litchi downy blight, caused by Peronophythora litchii, is one of the most serious diseases in major litchi-producing regions worldwide. The ankyrin (ANK) repeat is one of the most common protein-protein interaction motifs found in all kingdoms of life ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Circadian Oscillations in Branchlet Angle and Irradiance‐Dependent Acclimation in Chara braunii Under Continuous Light

Plant Direct, Volume 10, Issue 10, October 2026.
ABSTRACT Endogenous biological rhythms are central to temporal organization in land plants, yet their evolutionary origins in streptophyte algae remain unresolved. We investigated whether rhythmic morpho‐physiological processes in Chara braunii are consistent with endogenous regulation and how continuous light intensity modulates these responses. In C.

Chemical Control of Phytophthora sojae: Sensitivity of Isolates and Effects on Soybean Seed Germination and Seed Rot

Journal of Phytopathology, Volume 174, Issue 5, September/October 2026.
ABSTRACT Phytophthora sojae is an oomycete responsible for causing seedling damping‐off and root and stem rot in soybean. Seed treatment with chemical products is one of the management strategies that can be used to control the disease. Thus, the objective of this study was to evaluate the in vitro sensitivity of P.

Occurrence of Globisporangium sylvaticum Causing Lettuce Bottom Rot and Associated to Onion and Common Bean Roots in Brazil

Journal of Phytopathology, Volume 174, Issue 5, September/October 2026.
ABSTRACT Globisporangium sylvaticum is a soil‐borne oomycete associated with diseases in a wide range of plant species. Here, we report the first occurrence of G. sylvaticum causing bottom rot in lettuce and its association with rotted roots of onion and common bean in two geographic regions of Brazil.

Bulbochaete augustowiensis Szym. sp. nova (Oedogoniales, Chlorophyta) found in Poland

Acta Societatis Botanicorum Poloniae, 2014
A new species of Chlorophyta-Bulbochaete augustowiensis was found in Poland. This species differs from Bulbochaete echinospora Lacerda by the size oogonia, and slightly by the size of the reduced male filaments and vegetative cells.
