Interspecific hybridization may trigger species radiation by creating allele combinations and traits. Cultivated potato and its 107 wild relatives from the Petota lineage all share the distinctive trait of underground tubers, but the underlying mechanisms for tuberization and its relationship to extensive species diversification remain unclear. Through analyses of 128 genomes, including 88 haplotype-resolved genomes, Zhang et al. revealed that Petota is of ancient hybrid origin, with all members exhibiting stable mixed genomic ancestry, derived from the Etuberosum and Tomato lineages ca. 8-9 million years ago.

To investigate plants’ airborne sound emissions, Khait et al. constructed a reliable recording system, where each plant is recorded simultaneously by two microphones; first, they recorded plants within an acoustic box and developed machine learning algorithms to classify the recorded sounds; then they tested the system in a greenhouse, while monitoring physiological parameters of the recorded plants.
