Covering 1965 to February 2024 Plants are prolific peptide chemists and are known to make
thousands of different peptidic molecules. These peptides vary dramatically in their size …

The last years have seen a steady increase in our understanding of legumain biology that is
driven from two largely uncoupled research arenas, the mammalian and the plant legumain …

Programmed cell death (PCD) in animals depends on caspase protease activity. Plants also
exhibit PCD, for example as a response to pathogens, although a plant caspase remains …

Vacuoles play central roles in plant growth, development, and stress responses. To better
understand vacuole function and biogenesis we have characterized the vegetative vacuolar …

Vacuolar processing enzyme (VPE) is a cysteine proteinase originally identified as the
proteinase responsible for the maturation and activation of vacuolar proteins in plants, and it …

Proteolytic enzymes are intricately involved in many aspects of plant physiology and
development. On the one hand, they are necessary for protein turnover. Degradation of …

Plants exhibit an ultimate case of the intracellular motility involving rapid organelle trafficking
and continuous streaming of the endoplasmic reticulum (ER). Although it was long assumed …

Almost all plant cells have large vacuoles that contain both hydrolytic enzymes and a variety
of defense proteins. Plants use vacuoles and vacuolar contents for programmed cell death …

Plant vacuoles are multifunctional organelles. On the one hand, most vegetative tissues
develop lytic vacuoles that have a role in degradation. On the other hand, seed cells have …

The pH homeostasis of endomembranes is essential for cellular functions. In order to
provide direct pH measurements in the endomembrane system lumen, we targeted …
