Big news from our lab: we can now stably edit the genome of a parasitic plant! Transgene-free, genome-edited P. japonicum in one generation! This will transform how we study #parasiticplants and other hard-to-transform plants.

New #preprint from the lab: When one plant parasitizes another, the impact goes beyond nutrient loss. We show that parasitism weakens the host plant’s immunity, leaving it highly susceptible to microbial infections. Find out why: www.biorxiv.org/content/10.6... #PlantImmunity #ParasiticPlants

From life-saving medicine to gourmet cheese – our microbe of the year 2026 is Penicillium 🌟

This brush mold 🧫gave us penicillin & launched the antibiotic era 💊, and is a common workhorse in biotech labs🧪.
And it makes your cheese delicious 🧀🐭

or mycotoxigenic fungi and fungal-like organisms (e.g., oomycetes). We are looking for a highly 
motivated and creative scientist with a strong background in mycology and/or the biology of fungi and 
fungal-like organisms that interact with plants. The successful candidate will be expected to develop a 
world-class, externally funded research program that integrates both fundamental and applied aspects 
of fungal biology within the context of plant pathology. We welcome applicants pursuing a wide range 
of research topics related to plant-associated fungi, including but not limited to mechanisms of fungal 
pathogenesis or symbiosis with plants, population genomics and evolution of fungal plant pathogens, 
plant-associated fungal microbiomes and plant-microbe interactions, and/or one health approaches to 
fungal diseases and antifungal resistance. Applicants working in other relevant research areas involving 
pathogenic, symbiotic, or mycotoxigenic fungi or fungal-like organisms that affect plant health are also 
encouraged to apply. The successful candidate will have significant opportunities for collaboration with 
faculty in plant pathology, microbiology, genomics, and agricultural sciences, and to contribute to 
addressing issues of importance to California’s agricultural and natural ecosystems.
The appointee primary teaching responsibilities will be teaching Introductory Mycology, an upperdivision lab class, and SAS 30, Mushroom, Molds & Society, a general education class for non-majors. 
Additional graduate and undergraduate teaching responsibilities may be assigned based on 
departmental needs and the candidate’s expertise. The department offers modern instructional 
facilities, including a newly renovated teaching laboratory.

Illustration depicting the ways in which fungi can exchange genetic material with each other. Starship mediated HGT is confirmed experimentally in this preprint.

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

Corinna Thurow is the last talk today before the free afternoon.

Verticillium effector (TRADE) interacts with host varicose protein (VCS). Used a forward screen to figure out insensitive mutants and identified a WIND1 transcription factor.

Dissecting the RNA binding capacity of the multi-RRM protein Rrm4 essential for endosomal mRNA transport RNA-binding proteins (RBPs) utilize multiple RNA-binding domains (RBDs) to engage with extensive mRNA networks. Understanding the intricate interplay of modular RBDs is essential for uncovering RBP fu...

Why do RBPs need multiple RNA-binding domains? We show transcriptome-wide that the endosomal mRNA transporter Rrm4 uses its three RRMs to differentiate functional binding sites from accessory ones. Great collaboration with @koenig-lab.bsky.social and Zarnack lab
