How do plant defense genes get activated?

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.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Overview of the CML reports

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

2,240 plant extracts from 1,299 different plant species of Dutch origin. That’s the collection of the Dutch Extract Library, which has recently been transferred to the Institute of Biology Leiden.

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

Optimality in plant properties and processing.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…
