Atlas identifies genome regions that regulate plant cell identity

Posted on May 21, 2021 by Amy McDermott

Zoom in on the leaf of a corn plant, and you’ll find a patchwork of about 20 different cell types. A recent study, published in Cell, provides an atlas of critical genomic regions that control cell identity in six different … 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 →
