Please share widely! We think MycoMobilome can go a long way to support high-quality TE annotations across fungi!
Also, try it on your favorite 🍄 genome and tell us what you think 😉
Great and fun community initiative to expand the number of annotated biosynthetic gene clusters in MIBiG!
📣 Our latest story just dropped on bioRxiv:: A structurally unique effector shared between Verticillium dahliae and Fusarium oxysporum is involved in cotton defoliation and virulence on other hosts www.biorxiv.org/content/10.6... 🧵

Many thanks to my colleagues for their help in getting this published. This took a mighty 16 months to get through the peer review process.
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

With the new year, is my time to say bye to @gmivienna.bsky.social as I move to @zmbp-tuebingen.bsky.social in Tuebingen. I will start my solo Group Leader career as a Emmy Norther fellow. Thanks to everyone that helped on the way. I will be advertising PhD and Postdoc positions soon, stay tuned!
Left: Example images of colonies from gain-and-loss rate experiments after 12 days at 25°C. Cells derived from an aneuploid parent (top, green) and colonies derived from a euploid parent (bottom, magenta) each showing one progeny colony (indicated by an arrow) that converted in morphology bias. Bar indicates 10 mm. Conversion in morphology bias was used as a proxy for converting in ploidy. Right: Rapid gain and loss of Chr7 aneuploidy may increase phenotypic diversity. Summary scheme of the authors' data, suggesting that rapid gain and loss of the Chr7 aneuploidy may benefit Histoplasma by rapidly increasing phenotypic diversity, helping populations survive frequent and abrupt transitions between environment and host. Histoplasma grows as yeast in the mammalian body and in the laboratory when grown at 37°C, but as hyphae in the environment or in the laboratory when grown at 25°C. Cells with a second copy of chromosome 7 are biased towards hyphal growth and outcompete euploid cells in the yeast-to-hyphal transition (black arrows). Euploid cells (with one copy of each chromosome) are biased towards yeast growth and outcompete in the hyphal to yeast transition (black arrows). Cells frequently gain and lose a second copy of Chr7 (gray arrows). Cells with one copy of Chr7 have increased virulence in comparison to cells with two copies of the chromosome. Cells with two copies of Chr7 have a hyphal-biased transcriptome as do cells with increased copy number of HYF1, a TF on Chr7.
Thermally dimorphic #fungi like #Histoplasma switch between environmental filamentous & host-associated #yeast forms. This study shows that a rapidly reversible duplication of a #chromosome alters the efficiency of this switch, reducing virulence @plosbiology.org 🧪 plos.io/4qCC9Gf

Zoltán Cseresnyés, an older man with short gray hair and a friendly smile, stands indoors beside a long office table. He is wearing a light blue short-sleeved shirt, gray trousers, and brown shoes. He holds a small potted bonsai tree in both hands. On the table next to him are a large potted plant, a green watering can, and a book. The background shows a bright modern room with white walls and wooden flooring. In the upper left, a colorful speech bubble contains the text: “I am an image analyst. I help biologists and chemists to analyze their image data and get information and quantification out of microscopy images, thus allowing them to modify or plan experiments.” The Leibniz-HKI logo appears in blue at the bottom left, and an orange arrow points to the right.
Colorful calendar page for October 2025 from the Leibniz-HKI Calendar. The background fades from blue on the left to purple on the right. The word 'OCTOBER' appears in bold orange letters. Below it, the name 'Zoltán Cseresnyés' is written in large green text. At the bottom left, small black text reads 'Leibniz-HKI Calendar 2025' with the blue Leibniz-HKI logo beneath it. On the right side, the word 'SWIPE' is written in black uppercase letters next to an orange arrow pointing right.
A close-up photo shows the back of a man’s head as he looks at a computer monitor displaying a complex network of colorful lines and nodes on a dark background – microscopy data visualization. The desk below the monitor holds papers, computer accessories, and cables. In the top left, a colorful speech bubble contains the text: “The real highlight was being there at the very beginning of super-resolution microscopy.” The Leibniz-HKI logo appears in blue at the bottom left, and an orange arrow points to the right.
Zoltán Cseresnyés and a younger woman with dark hair, one of his colleagues, sit side by side at a table in a bright office. Zoltán, wearing a light blue short-sleeved shirt, gestures with his hand while explaining something on a laptop screen. The woman listens attentively, wearing a patterned blouse and a wristwatch. Behind them, large windows with blinds fill the room with natural light. A colorful speech bubble above them contains the text: “It is crucial to remain flexible and open – both in mind and in career.” The Leibniz-HKI logo appears in blue at the bottom left of the image.
🍁 Meet our #October #calendar 2025 feature: Zoltán Cseresnyés, imaging specialist at our @appsysbio.bsky.social research group. From 1980s Hungary to super-resolution microscopy at Cambridge, he now helps researchers unlock insights from complex images. 🔬🌌
