The fifth chapter of the Short History of Plant Science is now published as a preprint via Zenodo. This chapter deals with plant light microscopy, and covers topics such as Robert Hooke coining the term ‘cell’ to describe ‘cells’ while imaging cork in the 17th century, the development of the Cell Theory by Schleiden and Schwann, the revolution that was brought upon all microscopists with the parallel development of the Confocal Laser Scanning Microscope and GFP as a protein tag, and finally the more recent developments such as Super-Resolution Microscopy, Vertical-Stage Microscopes or Light-Sheet Microscopes.
Chapter 5 is online here:
Two Summaries of the main events covered can be found here
And all chapters are on the main page of the Series here:
Jacob has contributed to a new paper in Proceedings of the National Academy of Sciences of the United States of America on the structure of CESA3 with its substrate:
Structure of Arabidopsis CESA3 catalytic domain with its substrate UDP-glucose provides insight into the mechanism of cellulose synthesis
Our work with Dmitry Suslov from Saint Petersburg State University is finally published in Plant & Cell Physiology. Have a look at:
‘Brassinosteroids Influence Arabidopsis Hypocotyl Graviresponses through Changes in Mannans and Cellulose’
Liu has contributed to a Spotlight article for Molecular Plant, discussing recent findings by Yan et al. (2020), that pectins, more precisely β-1,4-galactans of rhamnogalacturonan I (RGI), play an important role in the plant’s salt stress response.
Salt with a sweet-tooth: Galactan synthesis impacts salt tolerance in Arabidopsis
Restrictions have been slowly lifted over the past three weeks, and we are a allowed to work more again. Hopefully, things will go back to semi-normal in January.
Victoria is opening up after I-don’t-remember-how-many-weeks-of-lockdown, but we here at the Plant Sciences division are still not allowed to increase our working hours.
So the Corona-Lockdown has been extended until October 26th. At that point it will be seven months that we have not been allowed to do anything but essential tasks (keeping plant lines alive, etc.).
A pretty bad year for everybody here at BioSciences UniMelb.
Well, that didn’t last long. We are back in lockdown with stage 4 restriction imposed in Melbourne.
Following the ‘Plant science’s next top models‘ review with contribution from Marc, we can already announce the next review from the team in Annals of Botany.
Liu is the first author on a new review discussing the links between phytohormone signalling and cellulose synthesis:
Associations between phytohormones and cellulose biosynthesis in land plants
Liu has covered abscisic acid, gibberellic acid, ethylene, salicylic acid and strigolactone, while Bret E. Hart from the lab of Ian Wallace has contributed parts on brassinosteroids, auxin and cytokinin, and Ghazanfar A. Khan from the Staffan Persson lab has contributed a paragraph on jasmonic acid.
Since restrictions have been partially lifted here in Victoria, we are now slowly returning back to campus. We still only have limited access to the different institutes and facilities, but at least we can work in the lab and office again for a couple of days per week. Better than nothing.
