Exploring the Natural Variation for Seedling Traits and Their Link with Seed Dimensions in Tomato

The success of germination, growth and final yield of every crop depends to a large extent on the quality of the seeds used to grow the crop. Seed quality is defined as the viability and vigor attribute of a seed that enables the emergence and establishment of normal seedlings under a wide range of environments. We attempt to dissect the mechanisms involved in the acquisition of seed quality, through a combined approach of physiology and genetics. To achieve this goal we explored the genetic variation found in a RIL population of Solanum lycopersicum (cv. Moneymaker) x Solanum pimpinellifolium through extensive phenotyping of seed and seedling traits under both normal and nutrient stress conditions and root system architecture (RSA) traits under optimal conditions. We have identified 62 major QTLs on 21 different positions for seed, seedling and RSA traits in this population. We identified QTLs that were common across both conditions, as well as specific to stress conditions. Most of the QTLs identified for seedling traits co-located with seed size and seed weight QTLs and the positive alleles were mostly contributed by the S. lycopersicum parent. Co-location of QTLs for different traits might suggest that the same locus has pleiotropic effects on multiple traits due to a common mechanistic basis. We show that seed weight has a strong effect on seedling vigor and these results are of great importance for the isolation of the corresponding genes and elucidation of the underlying mechanisms

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
