Learning from nature: using plant-soil feedback principles to improve growth and health of a horticultural crop
Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

Calcium-dependent regulation of auxin transport in plant development
The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

A meta-analysis of wetland plant traits in relation to the strategies of wetland plants and the impacts on ecosystem functioning
What are trait-trait relationships in wetlands? To what extent the so-called leaf economics traits deviate from terrestrial ecosystems? How traits specific to wetland plant relate to plant strategies? What’s the relationship between wetland plant traits to the ecosystem functioning (e.g. productivity,…

Nieuwe planten produceren zonder zaaien
Zonder een gewas opnieuw te zaaien toch nakomelingen produceren, die zelfs groter kunnen zijn dan de ouderplant. Volgens Leidse onderzoekers is dat mogelijk door het overstimuleren van één gen. Daarmee verjongt een cel en gaat deze terug naar de embryonale fase.
