Journal Club: Understanding how a plant makes a hook could someday improve crops

Posted on April 12, 2019 by Amber Dance

This spring, as the first shoots of new plants emerge from the soil, many are bent over in a hook. This simple act protects the fragile stem tip and leaves as the sprout pokes up through the dirt. But how … Continue reading →

Journal Club: Plants load extracellular vesicles with a new class of RNAs

Posted on February 19, 2019 by Jyoti Madhusoodanan

A recent study in The Plant Cell found that plants release extracellular vesicles carrying a new class of RNA molecules, named “tiny RNAs.” The findings are among the first to reveal the contents of these vesicles, and may hint at … Continue reading →

Journal Club: Insights from 3-D images defy assumptions about how plant cells communicate

Posted on June 23, 2017 by Carolyn Beans

When plant cells communicate, plasmodesmata serve as crucial conduits. These channels cross cell walls, linking one cell to its neighbor. If a plant needs to grow larger or fight off a pathogen, molecular signals pass through plasmodesmata to keep cells … Continue reading →
