Rapid redirection of auxin fluxes during root gravitropism by translocation of NGR proteins driving polarization of PIN-activating kinases biorxiv.org/cgi/content/sh… #bioRxiv
VAS2870, used as and NAPDH oxidase inhibitor, does not inhibit NADPH oxidases very well. Instead, it causes auxin transport defects leading to complete loss of gravitropism. Watch auxin reponrter R2D2, where lack of yellow signal = accumulated auxin. biorxiv.org/content/10.110…
ROS bursts after auxin, RALF, eATP or mechanical bending? We monitored them all. What triggers them and what are they good for? Many surprises! Read our new preprint, a second one in a row. Thanks ISTA and Biology Centre CAS for amazing environment. biorxiv.org/content/10.110…
Armadillo Repeat Only proteins enable function of multiple, if not all CNGC channels. These are essential for plethoha of calcium signals triggered by stresses, hormones and pathogens. Read our new perprint. biorxiv.org/content/10.110…
I'm hiring a postdoc. The pay is average, but the biological question and preliminary data on the project are outstanding. I will gladly share more to those who are seriosuly considering. jobs.bc.cas.cz/en/detail/223
My grandfather built motors that powered big machines. In a lab not so different from his workshop, my colleagues and I uncovered the assembly of the bacterial motor. Today, this discovery has been published in @NatureMicrobiol #MolecularNodes #Discovery nature.com/articles/s4156…
Although mostly distantly and historically, I'm very proud to be a part of this. Trichomes are indeed fascinating structures. Blue - cell wall autoflourescence, yellow- PI4P, magenta - chlorophyl. doi.org/10.1093/plcell…
If you want to know more about the interplay of NGR1 and AGC kinases, have a look at our recent work below!
This “fundamental” study addresses the earliest events that enable plant roots to reorient growth in response to gravity. elifesciences.org/articles/91523…paign=organic
Finally, the reviewed preprint on our efforts about the interplay of NGR and AGC kinases is out on @eLife . Please read here: doi.org/10.7554/eLife.…

In our new lab, we are opening 2 new positions, one PhD, one postdoc. So if you are interested in cell polarity, consider. jobs.bc.cas.cz/en/detail/197 jobs.bc.cas.cz/en/detail/198

It’s just amazing. I really need to think about this. Four different plasmids with pigment genes. Grown up in E. coli individually, mixed, and plated. Wow. @univpugetsound @ASMicrobiology
Big congrats to Matyas!

In some species, Seeds from the same plant source, ‘siblings’ appeared to recognise each other using chemical cues. They grow less invasive lateral roots allowing their ‘sibling’ an equal right to resources and their leaves would touch and intertwine 1/3

Please welcome a new player in the ROP GTPase cycle - Armadillo Repeat Only proteins. Watch a little teaser to our just released article in the Nature Plants. nature.com/articles/s4147…
Watch what happens with the root hairs instantly after the air bubble is gone.
Arabidopsis trichome has two distinct plasma membrane domains with different lipid composition. Each domain binds different EXO70 paralog. Check out our new paper in the special cell wall issue of IJMS mdpi.com/1422-0067/20/1….
