Scientists solve a thorny problem

"Why do plants have thorns?" is an easy question: The thorns help protect against hungry animals that like to munch on the plants. "Where do thorns come from?" is a more complicated question—but Yale scientists have found ...

Genetic self-activation maintains plant stem cells

Branching allows plants to occupy space in three dimensions, an innovation considered essential for their adaption. Stem cells are key to this process because they promote the establishment of new growth axes. But where do ...

Study finds signal cascade that keeps plant stem cells active

Pools of stem cells in the apical meristems of plants are key to continued growth and development. Understanding how these stem cells are maintained and balanced against differentiated cells could lead to methods for increasing ...
