What happens when a flower is eaten or pollinated? A study in the American Journal of Botany shows one interaction can impact in an unexpected way on another.
Post-anthesis colour change (PACC) is widespread in the angiosperms. Yet we know little about how this trait operates at the molecular level. By comparing the transcriptomes of pre- and post-colour change flowers in...
Red flowers have evolved repeatedly across angiosperms and are frequently examined in an ecological context. However, less is known about the biochemical basis of red colouration in different taxa. In a recent study...
Despite appearances – and often therefore assumptions – to the contrary, the intense blue-colour of the fruit of Pollia condensata is not due to pigment(s). Instead, it is another example of so-called ‘structural...
