Ecological effects of cell-level processes: genome size, functional traits and regional abundance of herbaceous plant species.

abstract：Background and Aims:Post-anthesis colour change (PACC) is widely thought to be an adaptation to signal floral suitability to pollinators. Lotus filicaulis and Lotus sessilifolius are insect-pollinated herbaceous legumes with flowers that open yellow, shift to orange and finally red. This study examines the molecular ba...
