Someone in the Arabidopsis/clock community seems to deeply dislike my work on research culture. Just want to say: whoever you are, please write & debate me directly instead of cowering behind anonymous grant reviews that threaten my students’ work. (2nd year in a row)

Preprint alert!

I am extremely happy to finally (!) share our work on the redox-dependent regulation of the CRKs in plants!

We integrated high-throughput interactomics, redox proteomics, structural modelling, and genetics to map a ROS-dependent CRK interaction landscape in Arabidopsis.

Ever wondered how the #cuticle, a hallmark of land plants, was established?

In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

Someone got Cas9-Turbo to work. It's like basically Y1H but with proteomics. It however requires transgenic plant expressing Cas9-Turbo and gRNAs, which is still cumbersome for many plants that are not Arabidopsis. #PlantSciences

Plants and animals evolve radically different body plans.

Do they also operate under fundamentally different molecular evolutionary constraints during organ formation?
