Why are plants not black?
All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

Fewer flowering plants in Dutch nature: national and international media coverage
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…

Green miner: new plant species mines metal
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…

Why plants in wetlands are highly productive
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…

Together, plants and fungi could slow down climate change
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.…

New light on innate plant immunity
Plants are able to resist a pathogen’s attack by a dual innate immune system. The relationship between the two pathways was not clear, but it turns out that they mutually potentiate each other, as assistant professor Pingtao Ding (Institute of Biology Leiden) and colleagues (The Sainsbury Laboratory,…

Discovery and exploitation of the transcriptional regulatory system of pectinases in Aspergillus niger
Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.
