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

Reading this as a pre-print a bit over a year ago really changed the way how I think about plant cell/organ types - great to see the final version in press. Congratulations to all authors for the wonderful, thought-provoking work!

Plants and animals evolve radically different body plans.

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

Last week I saw @leonardojo.bsky.social present a summary of his postdoc work, and I was so impressed about his ability to draw overarching themes and draw ideas from his various postdoc projects.

It made me contemplate the importance of taking a step back and look at the big picture. (1/4)

This also reminded me that I may have forgotten to celebrate the fact here that he was awarded a prestigious Dutch Talent Program VENI fellowship earlier this year!

This allows him to carry out independent research on his chosen topic, pioneer factors! πŸŽ‰

The projects were on

1) chickpea exodermis with me (www.biorxiv.org/content/10.1...)

2) effector-triggered immunity with @dinglab.bsky.social (www.biorxiv.org/content/10.1...)

3) far-red responses with @ronaldpierik.bsky.social.

Fig. 2 (shortened, full legend in paper): Perturbations of SlMYB41, SlMYB92, and SlWRKY71 expression affect the suberization of tomato exodermis. (A) Percentage of cross-sections showing a non-suberized, an early suberized (suberin in <50% of exodermal cells), or a late suberized (suberin in >50% of exodermal cells) exodermis phenotype in hairy root cultures of the control (empty vector), CRISPR knockout lines [Slmyb41-ko, Slmyb92-ko, Slwrky71-ko(4), and Slwrky71-ko(5)], and overexpressing lines (SlMYB41-OX, SlMYB92-OX, and SlWRKY71-OX). The number above the bars represents the number (n) of individual roots examined in each genotype. Asterisks denotes statistically significant differences between each line in comparison with the empty vector control, whereas n.s. indicates no significant differences (P<0.05, Ο‡2 test).
