Potentially key gene has big role in natural variation of chloroplast size

Worldwide populations of Arabidopsis thaliana all have the same genes, but they vary in many traits, including the size of their chloroplasts. A recent study in Plant Physiology identified one of the genes, FtsZ2-2, contributing to the natural variation in … Continue reading

Unlocking a mystery of seed development promises fatter, oilier oilseeds

The canola cooking oil lining supermarket shelves comes from the seeds of Brassica napus, a weedy-looking plant in the mustard family. Farmers of this crop understandably want varieties that yield big, oily seeds. A recent study in The Plant Cell … Continue reading

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

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

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

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
