Hornwort genomes could lead to crop improvement

Some 500 million years ago—when our continents were likely connected in a single land mass and most life existed underwater—hornworts were one of the first groups of plants to colonize land. But biologists have never ...

How plants sound the alarm about danger

Just like humans and other animals, plants have hormones. One role of plant hormones is to perceive trouble—whether an insect attack, drought or intense heat or cold—and then signal to the rest of the plant to respond.

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 ...

Genome editing strategy could improve rice, other crops

Scientists at UC Davis have used CRISPR technology to genetically engineer rice with high levels of beta-carotene, the precursor of vitamin A. The technique they used provides a promising strategy for genetically improving ...
