Agricultura i alimentació: realitats presents i desafiaments futurs
2015
Uno de los retos de la humanidad es como alimentar a una población en crecimiento sin dañar al planeta. Pensar en las necesidades actuales sin obviar que las decisiones que tomemos pueden poner en cuestión las generaciones futuras. La clave es el punto de equilibrio entre intensificación y sostenibilidad, dos conceptos que demasiado a menudo, se han visto como contradictorios y que mediante la innovación deben retroalimentarse.
Haplotype analyses reveal novel insights into tomato history and domestication driven by long-distance migrations and latitudinal adaptations.
2022
Abstract A novel haplotype-based approach that uses Procrustes analysis and automatic classification was used to provide further insights into tomato history and domestication. Agrarian societies domesticated species of interest by introducing complex genetic modifications. For tomatoes, two species, one of which had two botanical varieties, are thought to be involved in its domestication: the fully wild Solanum pimpinellifolium (SP), the wild and semi-domesticated Solanum lycopersicum var. cerasiforme (SLC) and the cultivated S. l. var. lycopersicum (SLL). The Procrustes approach showed that SP evolved into SLC during a gradual migration from the Peruvian deserts to the Mexican rainforests…
RNA-seq transcriptome analysis provides candidate genes for resistance to Tomato leaf cur New Delhi virus in melon
2022
[EN] Tomato leaf curl New Delhi virus (ToLCNDV) emerged in the Mediterranean Basin in 2012 as the first DNA bipartite begomovirus (Geminiviridae family), causing severe yield and economic losses in cucurbit crops. A major resistance locus was identified in the wild melon accession WM-7 (Cucumis melo kachri group), but the mechanisms involved in the resistant response remained unknown. In this work, we used RNA-sequencing to identify disease-associated genes that are differentially expressed in the course of ToLCNDV infection and could contribute to resistance. Transcriptomes of the resistant WM-7 genotype and the susceptible cultivar Piñonet Piel de Sapo (PS)(C. melo ibericus group) in ToLC…
