In Dutch nature, plant species that depend on pollination by insects are disappearing. Environmental scientist Kaixuan Pan shows this after analysing 87 years of measurements from more than 365,000 locations. Several national and international media reported on the study results. Below is an overview…

A plant that takes metal from the ground all by itself: a natural way to mine or to clean the soil. PhD student Roderick Bouman (Hortus Botanicus Leiden) described a new plant species from Sabah, Borneo, which can be used to extract nickel. In an open access article in Botanical studies, he and the…

Plants love favourable microbes such as bacteria and fungi: they grow better and become healthier. Jos Raaijmakers, Professor of Microbial Ecology, is in search of the right microbes to be used in agriculture. Inaugural lecture 13 November.

Environmental scientists in Leiden have found that the so-called leaf economics spectrum for plants can not only be applied to terrestrial ecosystems, such as forests and grasslands, but also to wetlands. Furthermore, they showed that wetland plants generally have a fast-return strategy, meaning they…

Remko Offringa has been appointed Professor in the field of Plant Developmental Genetics within the Faculty of Science at the Institute of Biology Leiden (IBL) from the 1st of April 2017.

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

Drained leaves and plants stripped bare. Insects can completely destroy crops. Soon, these situations may be behind us, with the new pesticide developed by Leiden and Wageningen researchers. With their plant-based ‘insect glue’, insects are incapacitated.

Leiden physicists are helping Wageningen plant researchers to study unpredictable plant embryos. For this, they are using a novel two-photon fluorescence microscope, aided by a 30 thousand euro ZonMW grant.

A special relationship between plants and fungi, which plays an important role in carbon storage in soil, has the potential to slow down climate change. However, the amount of carbon stored in soil is decreasing as a result of human activity. This is what researchers say in a publication in Nature Communications.…
