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.

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!
18 Nov 2024
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

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
