🧵1/X 🚨New Preprint🚨 Root pathogens are hard to manage, and we know little about plant genes enabling infection (susceptibility genes). Here, we show that SCARs are susceptibility factors in barley roots - and their loss affects pathogens/symbionts in distinct ways www.biorxiv.org/content/10.6...
Update on the numbers for the
Webinar on 20 April 2026 -
Healthy nursery plants:
470 registered participants,
from 243 different institutions/companies,
from 50 countries!!
If you manage a plant nursery or are interested in the prevention or management of devastating #Phytophthora spread then this is the seminar for you. @forestresearchuk.bsky.social @phytophthorarc.bsky.social
Wow!
2 days after the first announcement, we already have
190 registered participants
from 120 different institutions/companies
from 32 countries!!
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.

As a forest researcher, I very often (far too often) encounter questions such as: What does a forest researcher do in Spain? Do you even have forests there? The international image of Spain as a mostly desert-like country, and mainly associated with sun and beach,has contributed to this stereotype.
