Melon landraces are highly appreciated by consumers who pay price premiums to compensate for lower yields, enabling on-farm conservation. However, they are highly susceptible to soilborne diseases. This study analyses the impact of Cucurbita and Cucumis rootstocks on the accumulation of flavor-related metabolites in Spanish landraces of the Ibericus melon group, as a strategy to promote their sustainable cultivation.

Article Synopsis
  • The study investigates the antioxidant and antifungal properties of the cliff rose, a halophyte that thrives in saline environments, focusing on its hydromethanolic flower extract.
  • Key phytochemicals identified include fatty acids and phenolic compounds, which were tested for antifungal efficacy against various soil-borne plant pathogens.
  • The extract, especially when combined with chitosan oligomers, showed strong antifungal activity, outperforming some synthetic fungicides, indicating its potential as a natural agricultural solution.

Spain is a secondary centre of the diversification of the melon ( L.), with high diversity represented in highly appreciated landraces belonging to the Flexuosus and Ibericus groups. A collection of 47 accessions of Flexuosus, Chate, Piel de Sapo, Tendral, Amarillo, Blanco, and Rochet was analysed using a genotyping-by-sequencing (GBS) approach.

Tomato leaf curl New Delhi virus (ToLCNDV) emerged in the Mediterranean Basin in 2012 as the first DNA bipartite begomovirus ( family), causing severe yield and economic losses in cucurbit crops. A major resistance was identified in the wild melon accession WM-7 ( 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.
