Molecular feedback-loop for plant growth

Plant growth is not a uniform process: Plants grow in length at the shoot and root tip in particular, while in other places they form new leaves or flowers. These different processes must be coordinated with each another ...

A new role of autophagy in plant cell differentiation revealed

A midlife career change is hard to pull off, because it can involve reinventing yourself and adopting a completely new professional role. Now, researchers from Japan show that some plant cells get a helping hand from autophagy ...

The evolution of evolutionary developmental biology

Studying evolution by focusing solely on fossils would leave many questions unanswered, but evolutionary developmental biology (otherwise known as "evo-devo") helps fill in the gaps.

How did vertebrates first evolve jaws?

Five-hundred million years ago, it was relatively safe to go back in the water. That's because creatures of the deep had not yet evolved jaws. In a new pair of studies in eLife and Development, scientists reveal clues about ...

How do plants know how big to grow?

Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms ...

Mind the gap: Space inside eggs steers first few steps of life

Imagine sitting at a meeting where the shape of the table and your place at it might impact how you get along with the other members. Cells also communicate with their nearest neighbors, and in embryos, nothing is left to ...
