Interesting news item + small movie about our collaborator Jill Farrant: "Resurrecting crops from the devastation of drought" | Wageningen Seed Lab | Scoop.it

      Jill Farrant didn’t believe her eyes. This couldn’t be the same plant she’d seen the day before, lifeless and withering. She triple checked to be sure. No mistake: after rainfall the plant had come back to life. Farrant was nine at the time. Nobody believed her, but the moment inspired her to become an expert in resurrection plants.

New WSL publication: "Combined transcriptome and translatome analyses reveal a role for tryptophan‐dependent auxin biosynthesis in the control of DOG1‐dependent seed dormancy" in New Phytologist

New WSL publication: "Combined transcriptome and translatome analyses reveal a role for tryptophan‐dependent auxin biosynthesis in the control of DOG1‐dependent seed dormancy" in New Phytologist | Wageningen Seed Lab | Scoop.it


By Bing Bai, Ondrej Novak, Karin Ljung, Johannes Hanson and Leonie Bentsink.


The importance of translational regulation during Arabidopsis seed germination has been shown previously. Here the role of transcriptional and translational regulation during seed imbibition of the very dormant DELAY OF GERMINATION 1 ( DOG1 ) near-isogenic line was investigated.  Polysome profiling was performed on dormant and after-ripened seeds imbibed for 6 and 24 h in water and in the transcription inhibitor cordycepin. Transcriptome and translatome changes were investigated.  Ribosomal profiles of after-ripened seeds imbibed in cordycepin mimic those of dormant seeds. The polysome occupancy of mRNA species is not affected by germination inhibition, either as a result of seed dormancy or as a result of cordycepin treatment, indicating the importance of the regulation of transcript abundance.  The expression of auxin metabolism genes is discriminative during the imbibition of after- ripened and dormant seeds, which is confirmed by altered concentrations of indole-3-acetic acid conjugates and precursors.

Now open: call for proposals in the ZonMw/NWO Enabling Technologies Hotels programme with possibilities to get funding for (among others) the use of the GERMINATOR | Wageningen Seed Lab | Scoop.it

ZonMw and NWO have made funds available for the 4th call for projects within the ZonMw programme Enabling Technologies Hotels. The call was set up in collaboration with the Dutch Techcentre for Lifesciences (DTL).

Wilco Ligterink's insight:
If you are interested in doing high-througput germination assays, you can write a project for max 30 k€. Also many other technologies are available within this programme

Het plantje Xerophyta viscosa is niet kapot te krijgen: het kan jaren van extreme droogte overleven. Wageningse onderzoekers proberen die eigenschap ook in andere gewassen ‘aan te zetten’, om ze bestand te maken tegen droogte.
