New Phytologist, EarlyView.Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development
New Phytologist, EarlyView.Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.

The effect of auxin and gibberellin on pollen germination and pollen tube growth of plum
During the two-year period, the effects of two plant hormones (auxin – NAA and gibberellin – GA3) on pollen germination and pollen tube growth were studied in vitro in three plum cultivars: ‘Nada’, ‘Čačanska Najbolja’ (from Serbia) and ‘Wangenheims ...

New Phytologist, EarlyView.Morphospace position and phylogenetic placements of Trimeriantha monopolyada. Summary Floral structure is a key aspect of angiosperm diversity. Recent research revealed that significant floral disparity was already present in the Cretaceous. However, our understanding of early floral diversity remains limited, as it is directly dependent on the fossil ...

Pollen longevity and viability dataset: an integrated resource for plant research and conservation
New Phytologist, EarlyView.The most common methods to estimate pollen viability. Summary Pollen viability and longevity are key traits in plant reproduction, with implications for gene flow, crop breeding, and ex situ plant conservation. However, published data on these traits remain dispersed across disciplines, languages, and methods, limiting their accessibility and reuse ...
