vi analysis also revealed morphological variability within wild species SP as a consequence of its adaptation to the different environments. Moreover, SLC was characterized by a wide range of morphological variability for plant architecture, inflorescences and fruit characteristics which makes this species a potential source in tomato breeding programmes.After this phenotypic characterization, the genetic diversity was explored by using the public genomic sequence of our collections which are available in the framework of VARITOME project. The identified SNPs were annotated, and their putative impacts were predicted by using SnpEff. The lowest number of variants was detected in SLL grups and the highest number of variants was detected in SP. SLC had a variation between SLL and SP, with lower levels in SLC Mexico. This fact agrees with the hypothesis for the domestication and diffusion of cultivated tomato in Mesoamerica. Additionally, GWAS analysis was carried out with this genetic data and revealed significant associations between 107 SNPs and 8 quantitative traits and a total of 30 SNPs associated with 7 qualitative traits. This analysis has allowed the identification of known genomic regions such as the associations between fruit weight and fw2.2 or fw9.2. However, regions with possible novel genes have also been detected such as the case of yellow fruit. These results reinforce the potential of our collection for breeding programmes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
