This cluster of papers explores plant signaling and communication mechanisms, including the role of glutamate receptor-like genes, electrical signals, and long-distance signaling in plant defense. It also delves into the use of mycelium-based materials, the evolutionary ecology of carnivorous plants, and the phylogenetic analysis of plant species. Additionally, it investigates neurobiological aspects and ion channels in plants, as well as the photosynthetic responses to various stimuli.
