Which plant hormones are critical in responding to drought conditions? How do plant hormone responses adjust to environmental changes? An article published in the journal Trends in Plant Science ...

Abscisic acid (ABA) is a key plant hormone produced in response to abiotic stress such as drought and salt. It is mainly synthesized in roots and vascular tissues and transported to specific sites to ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there’s a downside to this protective mechanism: The plant’s ...

When faced with harsh growing conditions, the energy plants typically expend on growth gets delegated towards a stress response induced by disease, salty soils and extreme weather. And according to a ...

In contrast to previous assumptions, the defense hormones salicylic acid and jasmonic acid do not always suppress each other in regulating plant chemical defenses against pests and pathogens. In trees ...

A group of researchers has discovered a previously unknown pathway that regulates whether a plant uses its resources for growth or stress tolerance. This discovery could enable the stress response to ...

Microbial factories provide a sustainable alternative to tree sap for producing elusive plant molecules, offering new insights into plant development. Plant SLs serve two roles: canonical ones act as ...

It’s 1665, and scientist Robert Hooke has just used his newly-invented light microscope to look at a thin slice of cork up close. He’s stunned to see that the tree bark is made up of thousands of tiny ...

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some ...
