Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

A publication in Nature Plants by a team of Leiden biologists has received national and international media attention. The researchers can have annuals flower multiple times thanks to a particular gene they discovered.

The figure of the barbarian has captivated the Western imagination from Greek antiquity to the present. Since the 1990s, the rhetoric of civilization versus barbarism has taken center stage in Western political rhetoric and the media. But how can the longevity and popularity of this opposition be accounted…

The main objective of this research is to map out the cities of the Roman Near East in the imperial period, with a focus on location, city size and urban features, in order to study the form the urban system and its levels of integration.

How did Angkor interact with regional urban centers? How did the settlement system impact the society's agricultural system and regional resilience?

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

Plant scientist Omid Karami is the first winner of the Krijn Rietveld Memorial Innovation Award. The jury praises the outstanding quality of his scientific research as well as the positive societal impact and commercial potential of his work.

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

‘It was a discovery we did not expect,’ says Remko Offringa, professor of Plant developmental genetics. Today he publishes a new trait of a versatile gene in Current Biology: it makes the difference in plants between herbaceous and woody stem growth. A useful feature to prevent dehydration.

A new report reveals five actions that leaders can take to contribute to economic development, advance global security and sustainability, and make space a safe and globally accessible domain.

The Master’s programme Vitality and Ageing trains its students to become academic Vitality and Ageing professionals and engaged citizens who are competent and trained internationally and interdisciplinary. They are able to contribute to solutions for the challenges facing our ageing society.

In a festive and intimate award ceremony, plant scientist Omid Karami received the first edition of the Krijn Rietveld Memorial Innovation Award out of the hands of Wim Klop, Director of the Biotechnology Center at DSM. Several speakers spoke about Krijn Rietveld and why Karami deserves the prize that…

Leiden biologists have shown that a gene present in plants, animals and yeasts does play an important role in plants, although for years the gene was considered unimportant. It turns out the gene plays a crucial role in the development of vascular tissue in plants. Publication in Nature Plants on 11…

Whilst the world is opening up, the teaching will continue in a hybrid form next academic year. During the past year, when all of us were bound to our home offices and computer screens, new forms of education had to be developed – some of which proved to be efficient in preparing the students for their…

Seven Leiden professors have been elected as members of the Royal Netherlands Academy of Arts and Sciences (KNAW). In total 23 new members will be inaugurated on Monday 13 September.

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.

Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer-scale mounds to grow. Leiden chemists Leon Jacobse and Marc Koper, together with physicist Marcel Rost, discovered the exact details, using a unique tunneling microscope.

Patients with the same illness often receive the same treatment, even if the cause of the illness is different for each person. This represents a new step towards ultimately being able to offer every patient more personalised treatment.
