The shoot meristem of land plants maintains the capacity for organ generation throughout its
lifespan due to a group of undifferentiated stem cells. Most meristems are shaped like a …

There is intense interest in using genome editing technologies to domesticate wild plants, or
accelerate the improvement of weakly domesticated crops, in de novo domestication. Here …

Epistasis between genes is traditionally studied with mutations that eliminate protein activity,
but most natural genetic variation is in cis-regulatory DNA and influences gene expression …

Plants must rapidly and dynamically adapt to changes in their environment. Upon sensing
environmental signals, plants convert them into cellular signals, which elicit physiological or …

Gene duplication is a powerful source of biological innovation giving rise to paralogous
genes that undergo diverse fates. Redundancy between paralogous genes is an intriguing …

Peptide hormones influence diverse aspects of plant development through highly
coordinated cell-cell signaling pathways. Many peptide hormone families play key roles in …

A striking paradox is that genes with conserved protein sequence, function and expression
pattern over deep time often exhibit extremely divergent cis-regulatory sequences. It remains …

Symbioses with beneficial microbes are widespread in plants, but these relationships must
balance the energy invested by the plants with the nutrients acquired. Symbiosis with …

Non-coding RNAs (ncRNAs) are not conventionally involved in protein encoding. However,
recent findings indicate that ncRNAs possess the capacity to code for proteins or peptides …

The highly diverse Solanaceae family contains several widely studied models and crop
species. Fully exploring, appreciating, and exploiting this diversity requires additional model …
