Even plants can have neighbour trouble
Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

Producing new plants without sowing
Producing offspring of a crop without sowing and that is even bigger than the parent plant. According to Leiden researchers this can be achieved by overstimulating a single gene that rejuvenates cells, including bringing them back to the embryonic phase.

Plant species disappear and reappear
The disappearance and reappearance of species of plants in the Netherlands is a normal phenomenon. In the period from 1981-2000 the number of plants to have disappeared was considerably lower than previously, whereas the number of species rediscovered is much higher. Climate change may be the cause.

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.

The strategy of plants: it’s all about balancing traits
Just like every other organism on Earth, plants’ ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance,…
