La isla de tomato

La isla de tomato enables analysis of salinity tolerance in wild Galapagos tomatoes (Solanum cheesmaniae, Solanum galapagense) by providing curated phenotypic and ion-content data from 67 accessions and two Solanum lycopersicum lines across over 20 traits.

Key Features:

• Data content: Curated datasets include measurements from 67 Galapagos tomato accessions and two commercial Solanum lycopersicum lines covering more than 20 traits related to growth, physiology, and ion content.
• Trait analysis: Quantitative comparisons of natural variation in salinity tolerance across accessions highlight highly tolerant accessions such as LA0317, LA1449, and LA1403 under salt stress.
• Research support: Data and trait summaries support identification and selection of phenotypes relevant to genetic studies of salinity tolerance and introgression into commercial tomato germplasm.

Scientific Applications:

• Genetic mechanism discovery: Comparative trait and ion-content data enable investigation of genetic determinants of salinity tolerance in wild relatives.
• Crop improvement: Trait selection data can be used to prioritize accessions and traits for breeding salt-tolerant Solanum lycopersicum varieties.
• Phenotypic variation studies: Multi-trait measurements facilitate studies of natural variation in physiological and growth responses to salinity among wild tomato accessions.

Methodology:

Plants were grown in a controlled hydroponic experiment with 10 days of salt stress, and growth, physiological responses, and ion content were measured and compared across accessions.
