Graphic recording of the workshop session. Key words, messages and topics covered are grouped by speaker(s). This visual summary is intended to capture the essence of the session, it obviously cannot resolve or explore in detail all the complex issues listed. The illustration was commissioned to the illustrator Zsofi Lang. "Building a diverse and inclusive community through effective teaching and mentoring"

One of my favorite transposon facts. Think LTR retrotransposons are a homogeneous group? The two main kinds -- Ty1 and Ty3 -- are as evolutionary diverged as GIANT SQUID and PINE TREES.

"We found an arabidopsis mutant developing stomata on the roots!"

Not buying it? Eggcellent! What you actually see is a horn of the hornwort Anthoceros agrestis (and what you read was probably my favorite 1st April joke we did in the lab).

So cool!

Marchantia might seem an unlikely biotech crop, but it’s worth trying. In Aurore’s thesis, we pushed this concept by engineering the auronidins with MpMYB14 and using the pigments to dye cotton. It ended up giving a very unique and beautiful product. #PlantScience www.biorxiv.org/content/10.6...

Fig. 1.Schematic diagram of tRNA-gRNA multiplexing for plant genome editing. (A) A plasmid is constructed containing a tRNA-gRNA cassette driven by the U6 promoter, together with a transcription unit for Cas9 expression. (B) After transformation into the plant, the primary RNA transcript is cleaved by the endogenous tRNA-processing enzymes RNase P and RNase Z, resulting in functional guide RNAs for genome editing.

Frangedakis et al. present an improved method for generating complex CRSIPR-mediated genome modifications in Marchantia polymorpha using the tRNA-gRNA approach together with an optimized protocol for thallus transformation.
