Roberto Bassi closes the #SOLRUB2025 with an online plenary presentation about nature-based engineering of plant #photosynthesis.

Austin Hart closes the last session at the #SOLRUB2025 conference with a presentation about #tomato volatiles. There are two main BCAA-derived #volatile pathways in tomato. GWAS on a tomato population revealed 113 QTLs associated to BCAA derived volatiles. They identified several candidate genes.

Laura Van der Jeucht follows at #SOLRUB2025 with a presentation about how far-red light increases sugar content in #tomatoes. Far-red light exposure changes the plant architecture. Photosynthesis is not affected but the plant increases CO2 consumption. Sugar source content is increased.

It’s been a great meeting… I think my brain might burst with me and exciting information and insights! #SOLRUB2025

Pascal Martin follows at the #SOLRUB2025 with a presentation about endopolyploidy in #tomato fruit development. Endoduplication increases transcription. Changes in the chromatin accessibility contribute to ploidy-specific gene expression changes.

We come back from the coffee break at #SOLRUB2025 meeting with Magdalena Rossi who is presenting about the molecular mechanisms behind #tomato morphogenesis.

Pratima Debnath closes the #abiotic_stress session at the #SOLRUB2025 meeting with a presentation about heat stress response in #tomatoes. Plants present #thermal_memory which help to survive high temperatures after an adequate priming. She describes some candidate genes associated with this process

Next speaker at #SOLRUB2025 is Sara Bergonzi which bring us their studies shout #potato cold and freezing tolerance. Usually potato varieties are frost sensitive. They found overlapping QTLs in several chromosomes for cold tolerance with several promising candidate genes.

Ivo Rieu follows in this morning session at the #SOLRUB2025. He presents about this important topic associated to #climate_change, heat tolerance in #tomatoes. Anther decrease in length with high temperatures reducing fruit-set. Breed new varieties to overcome this problem is needed.

Day 4 at #SOLRUB2025 starts with a #potato presentation by Salome Prat @cragenomica.bsky.social. She talks about the molecular players involved in the tuber formation. Tubers are modified branches. A SC-RNAseq experiment showed clear separation between vascular and storage cells in tubers.

7 members of the FDFE team stand in front of the posters at the SolRub 2025 meeting.

Several members of the #FDFE team participate in the #SolRub2025 meeting in Torino, Italy this week. 3 talks and 3 posters presented. Stimulating meeting gathering specialists of the Solanaceae and Rubiaceae communities.

Lucas Munnes just provided some update on Morelloid genomes and where Solanum nigrum might have come from at #SOLRUB2025

It took us a very long time but here is Arslan with the Nicotina glauca genome and the leaf developmental series transcriptome and metabolome at #SOLRUB2025

Lucas Munnes closes this Wednesday’s session at the #SOLRUB2025 presenting about a #pangenome in the Morelloid clade. Different species have different levels of polyploidy with S. nigrum being highest (6x). Synteny with S. americanum (2x). For nigrum subA ~ americanum. subB & subC ~ villosum (4x).

Switching from biodiversity to the omics technologies session at the #SOLRUB2025. Presenting Adi Avni about plant-based sensors. The idea , convert plant gene responses in a signal read by an electrode that can transmit the information to a computer.

Vivien out of her usual lichen track presents the analysis of Alkengi officinarum and transcriptomic change during the calyx color change at #SOLRUB2025.

Vivien Joisten-Rosenthal follows with a presentation about the Alkakengi officinarum genome at the #SOLRUB2025. This species, although it is close related with the Physalis, presents important differences: bigger genome and moderate collinearity with Physalis. Its calyx is orange colored.

Great job by Erin for her first ever oral presentation. #SOLRUB2025 Our paper describing part of the work presented can be found here: link.springer.com/article/10.1...

Jean-Philippe Claude brings us his research at the #SOLRUB2025 about ecology and phenology of rubicaceae species in the Antilles. These islands have a high biodiversity driven by different habitats. The mountains produce different environments producing habitats for 6 rubicaceae species.

Arnaud Bovy presents us at #SOLRUB2025 about the increased firmness in the Ty1 introgression in #tomato. This introgression comes from S. chilense LA1969 and it is located in chromosome 6.

Naama Menda presents now the Sol Genomics Network (SGN) database and the BreedBase system at the #SOLRUB2025. SGN is a #Solanaceae based database with genomes, transcriptomic data, metabolic pathways, and manually curated genes.

Erin P. Rini follows at #SOLRUB2025 with a #pepper presentation about the screening of a germplasm bank for a resistance to #white_flies. Trichomes, cuticles and secondary metabolism compounds (phenolic acids) are three of the resistance mechanisms in pepper against this pest.

Jaime Prohens brings us a wonderful presentation about the importance of #eggplant populations to elucidate the molecular players in agronomical traits at #SOLRUB2025. Having a good population was essential to identify the gene behind the formation of #pickles in eggplants.

Luciana Gaccione closes the session at the #SOLRUB2025 describing their work building an #eggplant graph-based #pangenome and its application to identify genes behind several agronomical traits.

Luciana Gaccione presents her phantastic results on the eggplant pangenome and panphenome at #SOLRUB2025.

Third day at #SOLRUB2025 starts with a presentation by Valerie Poncet which brings us a presentation of the use of genomic to adapt robusta to local environments. Coffee cultivation is heavy threaded by #climate_change and #deforestation. Canephora is divided into 8 genetic groups native to Africa.

Kyeonglim Min closes Tuesday’s sessions at the #SOLRUB2025 with a presentation about modifying coloration in #pepper fruits. They have modified the expression of the transcription factors CaNAC84 and CaNAC92.

Hiroshi Ezura follows at #SOLRUB2025 talking about CRISPR breeding in #tomatoes. The first CRISPR-modified cultivar was Sicilian Rouge with a higher #GABA content available in Japan, and soon in the US. They are working now in a variety with a high Brix content targeting the inventase inhibitors.

Laura Toppino follows at #SOLRUB2025 with her presentation about avoiding eggplant fruit flesh browning using CRISPR-Cas9 technology. Browning is produced by polyphenols. Chlorogenic acid is the main browning polyphenol in eggplants. It is caused by PPOs. Knocking out HQT reduces browning.
