The inset cover image shows the fleshy structures formed by the outermost seed integument (sarcotesta) of the gymnosperm Ginkgo biloba, which are attractive to animals and thus act like angiosperm fruits from a functional point of view. B-sister genes appear to have a role in the formation of these structures where they have an ovular origin, suggesting that the ‘fruit function’ of the genes is quite old, being already present in gymnosperms as ancient as Ginkgoales. See Lovisetto et al. (pp. 535–544).
Most of the papers are subscription-only for year, when they’ll become free access. However some, like ‘Sustainable utilization and conservation of plant biodiversity in montane ecosystems: the western Himalayas as a case study‘ by Shujaul Mulk Khan, Sue E. Page, Habib Ahmad, and David M. Harper are available free now.
