Review: Plant networks as traits and hypotheses: Moving beyond description ($) In Star Wars Episode 2, Obi Wan identifies the location of a missing planet by walking through a 3D projection of the galaxy. I’ve always hoped that if we obtain enough data and figure out how to display it properly, we’ll “see” what parts […]

New Teaching Tool “Computational Image Processing in Microscopy”

We’re excited to announce the publication of The Plant Cell’s latest Teaching Tool, “Computational Image Processing in Microscopy,” by Adrienne Roeder, available without subscription at Plantae.org (and in the October issue of The Plant Cell). The age of big data includes sophisticated imaging datasets. Computational image processing is essential for extracting quantitative information from these […]

Review: Revolutions in agriculture chart a course for targeted breeding of old and new crops ($) (Science)

A few traits are associated with domestication across many species. Eshed and Lippman provide an overview of the changes to plant stature and flowering time that have been repeatedly selected by our ancestors. By comparing the molecular underpinnings of these traits across crops, it becomes clear that many different genes can contribute to the desired […]

A reference genome for pea provides insight into legume genome evolution (Nature Genetics)

Pea (Pisum sativum) is an important protein-rich crop that introduces most students to the principles of Mendelian genetics, but it has lagged behind in the genomics era due to its much larger genome size than newer model legumes. Kreplak et al.  have now released an annotated chromosome-level reference genome assembly for pea. The authors note […]

Halotropism requires phospholipase Dζ1‐mediated modulation of cellular polarity of auxin transport carriers ($) (Plant Cell Environ)

Phospholipase D (PLD) enzymes cleave phosopholipds to release phosphatidic acid (PA), which is a signal that affects membrane dynamics. Previous studies have indicated a role for PLD and PA in root responses to osmotic and salt stress, but as the Arabidopsis genome has 12 genes encoding PLD questions remain about their specific functions. Korver et […]

Review: Metabolite control of translation by conserved peptide uORFs: The ribosome as a metabolite multi-sensor (Plant Physiol)

Not all mRNAs are translated equally. Between 25–50% of eukaryotic mRNAs have an upstream open reading frame (uORF) that affects translation of the main ORF (mORF). Usually the presence of an uORF inhibits translation, but under some conditions the ribosome can overlook the uORF or reinitiate translation and precede to translate the mORF. Many factors […]

A Rubisco-binding protein is required for normal pyrenoid number and starch sheath morphology in Chlamydomonas reinhardtii (PNAS)

In most eukaryotic algae, carbon fixation takes place in an organelle within an organelle, the pyrenoid inside of the chloroplast. Besides being functionally very important, pyrenoids are interesting because they are what is called a phase-separated structure, that is they are not membrane enclosed; rather, they are usually surrounded by starch granules known as starch […]

A CLE–SUNN module regulates strigolactone content and symbiosis (Nature Plants)

The symbiosis between plants and arbuscular mycorrhizal fungi is conditional. Plants that are limited for phosphate release strigolactones into the soil, promoting changes in the fungi that facilitate the symbiosis. Müller et al. found that a Medicago gene encoding a CLE peptide, MtCLE53, is induced upon root colonization. When this gene is ectopically overexpressed, plants […]
