The most sustainable biological process on the planet is photosynthesis since its mechanism allows us to take advantage of solar energy, water, and CO2 to produce chemical energy and photosynthates relevant to primary and secondary metabolism in different organisms. This mechanism has been extensively studied at the physiological, biochemical, and functional genomics levels. However, it is necessary to elucidate the genetic mechanisms of plant photosynthetic regulation in areas of high genetic diversity threatened by climate change. For example, the Solanaceae family encompasses more than 3,000 species distributed in megadiverse countries such as Peru, Ecuador, and Bolivia to preserve biodiversity and guarantee food security. Thus, the objective of this thesis was to carry out a comparative genomic analysis between the genes involved in 8 photosynthetic pathways of Capsicum annuum, Nicotiana attenuata, Nicotiana sylvestris, Nicotiana tabacum, Nicotiana tomentosa, Solanum lycopersicum, Solanum pennellii, and Solanum tuberosum; taking the A. thaliana proteome as a reference. In this sense, it was possible to identify 136 homologous genes of A. thaliana in the 8 Solanaceae studied and 24 genes that did not present homology. In addition, 99 unique orthologous sequences were obtained, and based on their relevance in the photosynthetic process, LPE1, HCF173, CRR23, NDH48, ATPC, RuBisCO, GAPB, and TPI were selected to perform a phylogenetic and motif analysis. LPE1, HCF173, CRR23, NDH48, and ATPC were the only genes with taxonomic consistency. On the other hand, motif analysis revealed high gene conservation. These findings are essential to understand the evolution of the photosynthetic apparatus in Solanaceae.
