The beneficial effects of biostimulants derived from the alga Ascophyllum nodosum have been documented for a wide variety of plant species. However, crops are part of complex agroecosystems, where different trophic levels interact and affect crop development. The present study aimed to assess the potential impact of A. nodosum in a tritrophic system consisting of the faba bean crop ( Vicia faba , L.) , the herbivore Aphis faba...

Key message Genome adaptation, driven by mutations, transposable elements, and structural variations, relies on plasticity and instability. This allows populations to evolve, enhance fitness, and adapt to challenges like climate change. Abstract Genomes adapt via mutations, transposable elements, DNA structural changes, and epigenetics. Genome plasticity enhances fitness by providing the genetic variation necessary for organis...

Main conclusion Plants lacking shoot apical meristem develop with unique body shapes, suggesting rewiring of developmental genes. This loss of the meristem is likely influenced by a combination of environmental factors and evolutionary pressures. Abstract This study explores the development of plant bodies in three families (Podostemaceae, Lemnaceae, and Gesneriaceae) where the shoot apical meristem (SAM), a key structure for...
