Science Highlights

Defective pollen tube tip growth induces neo-polyploid infertility

Westermann, J., et al., Science, Vol 383, Issue 6686 (2024)

Genome duplication in Arabidopsis arenosa causes low fertility due to pollen tube defects like slow growth and premature bursting. These issues improve in evolved polyploids, with specific genes linked to better performance, highlighting pollen tube growth as a key fertility challenge.

Escarpment evolution drives diversification of the Madagascar flora

Yi Liu, Y.W., et al., Science, Vol 383, Issue 6686 (2024)

Madagascar's rich endemic biodiversity evolved over millions of years, especially along the eastern escarpment. Precipitation-driven erosion and topographic changes create transient habitats, isolating species and driving allopatric speciation, contributing to its biodiversity.

Soil health associated with higher primary productivity across Europe

Romero, F., et al., Nature Ecology & Evolution (2024)

This pan-European study of 588 sites shows that soil health, higher in woodlands than in grasslands and croplands, is positively linked to productivity in croplands and grasslands. Soil biodiversity, particularly nitrogen-fixing bacteria and mycorrhizal fungi, is crucial for maintaining productivity.

A paternal signal induces endosperm proliferation ...

Simonini, S., et al., Science, Vol 383, Issue 6683 (2024)

Fertilization in multicellular organisms resumes the gametes' cell cycle, requiring both to be in the same phase. In Arabidopsis, a sperm signal triggers female central cell proliferation by degrading the RBR1 protein, allowing S phase progression, crucial for endosperm and seed development.

Multispecies deep learning using citizen science data produces more ..

Brun, P., et al., Nature Communications 15, 4421 (2024)

Using deep neural networks (DNNs) and citizen science data, researchers modeled the spatiotemporal distributions of 2477 plant species inSwitzerland. Multispecies DNNs outperformed traditional methods in predicting distributions and community composition, offering insights into phenology and future changes.
