Have you ever wondered how it is possible that systemically infected plants produce (a certain percentage of) healthy progeny? 💚
Check out the first preprint of the @incavirus.bsky.social lab and first preprint of my postdoc! 🍀
We'd be very happy about feedback and discussions!

Preprint alert! It is my great pleasure to announce the first manuscript from the lab, a story that started @gmivienna.bsky.social and was mainly accomplished by the intrepid @gesahoffmann.bsky.social at @mpi-mp-potsdam.bsky.social. A brief thread with our findings

AGO5 restricts virus vertical transmission in plant gametophytes
The propagation of a viral infection from a host parent to its progeny is known as vertical transmission, or seed transmission in plants. It allows viral infections to rapidly spread locally via polle...

Here we showed that auxin production after fertilization is a conserved, paternal-triggered mechanism for seed initiation in angiosperms.

Reprogramming of microspore fate via BBM-BAR1 for highly efficient in vivo haploid induction
Reprogramming of microspore fate via BBM-BAR1 for highly efficient in vivo haploid induction
Highlights - Ectopic BBM expression in microspores triggers in vivo androgenesis within anthers
- BAR1 is a direct BBM effector that reprograms microspore fate for embryogenesis
- BBM/BAR1 expression can substitute for stress treatment in androgenesis induction
- A conserved BBM-BAR1 module enables highly efficient in vivo haploid induction

SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance
Salicylic acid (SA) is a key phytohormone that orchestrates immune responses against pathogens, including Pseudomonas syringae bacteria. The timing and extent of SA accumulation are tightly controlled...

I just spent 40 min watching a YouTube video about AgriStarts (www.agristarts.com), a tissue culture company that produce 30 million plants/year for horticultural crops (e.g., houseplants, berries). Really impressed. Highly recommend the video.

• LEC2 and SPCH co-activate local auxin biosynthesis by targeting TAA1 and YUC4
• GMC-auxin state marks stomatal cells shifting from differentiation to totipotency
• Transcriptional rewiring and auxin signaling drive reprogramming of stomatal cells
