Getting quality transcriptome assemblies from Herbarium samples is possible biorxiv.org/content/10.1101/…. Work led by @AlexaTyszka. Another fun collaboration with @Phil_Carella and @Khongsam_Chia, who functionally validated an NLR immune receptor from a sample collected in 1956.

RNA from herbarium specimens is more stable than you think. Cool new study from @AlexaTyszka @evojfwalker and team. @Khongsam_Chia and I were happy to contribute by functionally validating an NLR immune receptor last expressed in 1956.
Herbaria provide a valuable resource for obtaining informative mRNA biorxiv.org/content/10.1101/… #biorxiv_plants

There is ONE WEEK left to apply for the #PlantScience #PhD position in my lab! This will use the latest #microscopy, #biosensor and #ecophysiology techniques!
The Rowe lab is recruiting a #PlantScience PhD student for 2025! You'll use our new ABACUS FRET biosensors to map the dynamic leaf #AbscisicAcid accumulations at low humidity in Arabidopsis, wheat and rice. #PhDposition

ALT A grey coloured Arabidopsis leaf epidermis, with black cell walls. Each cells has a colourful blobs - a nuclear localised fluorescent ABA sensor, with warm colours indicating high concentrations, and cooler colours indicating lower concentrations.
Excited to see this come out! Miles, an undergraduate in the lab, led this project and plans to keep it maintained and up to date as he transitions to being a graduate student. doi.org/10.1093/bioinformati…

Very happy to share the final version of our work on the evolution of broad host virulence in Pseudomonas out now @cellhostmicrobe It’s just in time for the holidays 🎄🦠 cell.com/cell-host-microbe/f…
Very happy to see this come out, awesome work by @AlexaTyszka and a fun chance to collaborate with @phylodrew !

Happy to share our study on the critical role of the lipopeptide syringomycin in promoting Pseudomonas syringae virulence across land plants. Project led by Kris Grenz and @Khongsam_Chia, @JohnInnesCentre and collaborators @AlexaTyszka & @evojfwalker biorxiv.org/cgi/content/shor…

🌐🔬The success of this method opens doors for similar studies across diverse species and ecosystems. Researchers can now explore transcriptomes in a more convenient and environmentally friendly manner. (6/6)

Natalia Ruiz-Vargas leads a paper showing you can get transcriptomes from tissue sitting out for six months. Hopefully makes data collection for phylotranscriptomics easier. A lot of fun working with @AlexaTyszka , Karolis, May, Eric and Robie. Link here: buff.ly/48OaE3P
Excited to be able to share this. Work led by Natalia, Karolis and @AlexaTyszka where they obtained and analyzed transcriptomes from tissue sitting on Natalia’s desk for up to six months. biorxiv.org/content/10.1101/…
Alexa Tyszka and Eric Bretz's first paper, with help from Holly, Miles, Karolis, and collaborators @phylodrew and @gwstull . The paper examines the similarities and differences between chloroplasts and mitochondria in a phylogenetic context. doi.org/10.3389/fpls.2023.11…
