Resumen
[ES] El cambio climático tiene un gran impacto en la agricultura mundial, lo que implica un aumento de las temperaturas y sequía que afecta a la productividad agrícola. Estos factores van a repercutir en los procesos bioquímicos y moleculares de las especies vegetales, influyendo en su producción y calidad. La transcriptómica es fundamental para comprender las vías de resistencia a la sequía, esto produce una mejora en varios cultivos. Este trabajo analiza el transcriptoma de 14 cultivares de olivo sometidos a sequía, utilizando RNA-Seq y análisis bioinformático. El objetivo principal es identificar los genes y vías de señalización involucradas en la respuesta a la sequía y comprender las diferencias en la capacidad de adaptación entre cultivares. Además, se realizó un análisis detallado del transcriptoma, comparando la expresión génica bajo condiciones de sequía y control. Se emplearon herramientas bioinformáticas y análisis de enriquecimiento que permitieron llevar a cabo este estudio. Este trabajo proporciona una base para la mejora genética de los olivos, potenciando las estrategias de selección asistida por marcadores para aumentar la resistencia a la sequía, la cual es vital para la sostenibilidad y productividad. A partir de los resultados obtuvimos genes comunes y específicos que responden al estrés hídrico.
[EN] Climate change has a significant impact on global agriculture, leading to increase temperatures and drought that affect agricultural productivity. These factors influence the biochemical and molecular processes of plant species, affecting their production and quality. Transcriptomics is fundamental for understanding the pathways of drought resistance, which leads to improvements in various crops. This work analyzes the transcriptome of 14 olive cultivars subjected to drought, using RNA- seq and bioinformatic analisys. The main objective is to identify genes and signaling pathways involved in the response to drought and to understand the differences in adaptation capacity among cultivars. Additionally, a detailed transcriptome analysis was conducted, comparing gene expression under drought and control conditions. Bioinformatic tools and enrichment analysis were employed to carry out this study. This work provides a foundation for the genetic improvement of olives, enhancing marker- assisted selection strategies to increase drought resistance, which is vital for sustainability and productivity. From the results, we identified common and specific genes that respond to water stress.
