Evolutionary flexibility in flooding response circuitry in angiosperms ($) Flooding is unpredictable and can lead to plant death due to insufficient oxygen (hypoxia). Some plant species and varieties are better able to survive periods of submergence. Here, Reynoso et al. looked at gene networks induced transcriptionally and translationally by flooding in rice, Medicago and two […]
In Star Wars Episode 2, Obi Wan identifies the location of a missing planet by walking through a 3D projection of the galaxy. I’ve always hoped that if we obtain enough data and figure out how to display it properly, we’ll “see” what parts are out of place or missing. But getting from simple linear […]
Autophagy is a recycling pathway that supports numerous processes, from nutrient remobilization to abiotic and biotic stress responses. Dauphinee, Cardoso et al. have developed a multi-step pathway that allows them to screen for inhibitors of autophagy in order to build a repertoire of new tools. For a high-throughput screen of autophagy inhibition, they start by […]
The parasitic plant Striga asiatica is both a serious agricultural pest and a fascinating plant oddity. Yoshida et al. report its genome sequence, which provides a glimpse into how a plant becomes an obligate parasite. Three key findings are the tremendous expansion of receptors for strigolactones (host-released signals that trigger Striga germination, leading to parasitism), […]
Review: Plant networks as traits and hypotheses: Moving beyond description ($) 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 […]
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 […]
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 […]
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 […]
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 […]
