Abstract:
... Oil-producing flowers have evolved specialized traits along with the ability to secrete oil as reward, leading to the expectation of a narrow relationship between floral architecture and oil-collecting behaviours of pollinators. Krameriaceae flowers have a showy calyx and a less conspicuous dimorphic corolla modified into a pair of elaiophores that secrete the oil, and a group of petaloid petals t ...

Abstract:
... Sexual plant reproduction is a strategy that allows plant populations to increase genetic variability, and consequently to be more efficient in adapting to new environments and to overcome stress conditions. Here, we focus on the reproductive mode of Phragmites australis, an important sub-cosmopolite species that can spread both by clonal propagation and sexual reproduction. In Europe, P. australi ...

Abstract:
... Quantifying the benefits of pollinator abundance and diversity for plant reproduction is a critical challenge, especially given recent pollinator declines. Many studies test for pollen limitation (PL), but huge gaps remain in our understanding of how often and why plants experience PL. Most studies are limited to a few sites or years. Little existing research mechanistically links pollinator visit ...

Abstract:
... Plant reproduction has broad implications for ecology and society (e.g., production of allergenic pollen), and a number of processes that affect flowering are affected by climate. In this study, we tested for variation in traits related to pollen production by the allergenic plant, common ragweed, across a climate gradient in Massachusetts. We tested whether traits that are easily-measured in the ...

For flowering plants, induction of defences to deal with herbivores can lead to disruption of plant–pollinator interactions. Current knowledge on the full extent of herbivore‐induced changes in flower traits is ...

Abstract:
... Changes from historic weather patterns have affected the phenology of many organisms world‐wide. Altered phenology can introduce organisms to novel abiotic conditions during growth and modify species interactions, both of which could drive changes in reproduction. We explored how climate change can alter plant reproduction using an experiment in which we manipulated the individual and combined eff ...

However, von Post was not the first to study pollen, and research dates back to the works of Nehemiah Grew and Marcello Malpighi in the late 17th century. Afterwards studies focussed mainly on the role of pollen for plant reproduction, and on pol ...

Abstract:
... AIMS: Copper (Cu) and cadmium (Cd) are toxic to plants at high levels. The current situation that many crops are growing on the farmlands with Cu or Cd contamination leads to a big threat to food safety. METHODS: Based on the small RNA (sRNA) sequencing data, hundreds of the sRNAs responsive to excessive Cu or Cd treatment were extracted. Degradome sequencing data enabled us to identify the target ...

DNA methylation and histone modifications are epigenetic changes on a DNA molecule that alter the three-dimensional (3D) structure locally as well as globally, impacting chromatin looping and packaging on a larger scale. Epigenetic marks thus inform higher-order chromosome organization and placement in the nucleus. Conventional epigenetic marks are joined by chromatin modifiers like cohesins, cond ...
