Phytophthora targets plant extracellular vesicles to promote infection a and b, TET8, TET9, PEN1, but not ARA6 could be detected in total extracellular vesicles (P100 pellet) of Arabidopsis. a, eGFP labeled proteins and plant actin were detected by western blotting. b, Confocal microscopy of EVs isolated from TET8-eGFP, TET9-eGFP, ARA6-eGFP and eGFP-PEN1 expressing Arabidopsis respectively. Bar, 10 µM. c, EVs were isolated from TET8-eGFP expressing lines. AWF (without EVs) were prepared by ultracentrifugation at 100,000 × g for 6 hours. Proteins were detected by western blotting. d, Schematic representation of purification of plant EVs by Size Exclusion Chromatography (SEC). e, Elution fractions of Size Exclusion Chromatography were collected. TET8-eGFP, TET9-eGFP and eGFP-PEN1 were detected by western blotting. Dashed box indicates collection of EV fractions for further analysis.

Time series plots comparing in situ soil moisture at −7–28 cm with multiple remote sensing/model products across different depths and ecosystems (forest and grassland). The figure illustrates product-specific deviations and uncertainties, emphasizing variability in soil moisture representation through the soil profile. - work in progress

#Soil #moisture is strongly depth-dependent—and so is plant water supply. Across ecosystem we (Marian Schönauer / me) highlight: #SMAP L4, #ERA5-Land shows substantial divergence vs in situ observations across #depths.

They showcase that the spread of invasive plant pathogens can be drastically reduced through effective biosecurity standards, improving plant quality while ensuring the economic viability of the nursery sector.

Nursery accreditation schemes have been operating successfully for years in Australia, California and recently the United Kingdom.

Extensive surveys conducted in more than 2,500 nurseries and a similar number of restoration and planting sites across Europe revealed near-ubiquitous infestation with over 120 Phytophthora species, most of them exotic.

Scientific studies have demonstrated that numerous declines and diebacks affecting horticultural crops, forests and natural ecosystems in Europe, Australia and the Americas are primarily caused by invasive soil- or airborne pathogens from the genus #Phytophthora.
