Metabolic labeling of RNAs uncovers hidden features and dynamics of the Arabidopsis transcriptome (Plant Cell)

The ability to directly sequence RNAs (RNA-seq) has revolutionized our understanding of gene expression, but it can miss or underestimate short-lived RNAs. Several methods have been developed to identify newly-synthesized mRNAs to provide a snapshot of transcription as it happens. Szabo present Neu-seq,…

Review: In vitro analytical approaches to study plant ligand-receptor interactions (Plant Physiol)

It seems every other paper shows a nice diagram of a signaling cascade that includes a receptor interacting with its ligand. However, sometimes these diagrams are little more than speculation or guesswork. It’s not always easy to figure out if this interaction is real. Here, Sandoval and Santiago review…

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy (eLIFE)

Advances in microscopy have greatly informed our understanding of fundamental plant processes, but the germline cells in flowers have been hard to image as they are tiny and embedded within other tissues. Valuchova et al. present a method using light sheet fluorescence microscopy that allows live cell…

Review: Methods to visualize elements in plants (Plant Physiol)

Plant Science Research Weekly: February 14 February 14, 2020/in Blog, WWR Full Post /by Mary Williams Review: Deep learning for plant genomics and crop improvement One of the goals of plant science is to use the molecular phenotype (genome, transcriptome, proteome) to predict the…

Reciprocal cybrids reveal how organellar genomes affect plant phenotypes (Nature Plants)

A cybrid is a cytoplasmic hybrid; in other words, a cell or organism in which the cytosolic genomes (mitochondria and plastid) have a different origin than the nuclear genome; the nuclear genome is inherited solely from the paternal parent, and the cytosolic genomes from the maternal parent. Starting…

Accurate and versatile 3D segmentation of plant tissues at cellular resolution (bioRxiv)

Advances in microscopy allow biologists to document and understand phenotypic changes at the tissue level. Despite this advancement, analysis of microscopic images to characterize changes in phenotypes is still under development. In this paper, Wolny et al. have developed an image analysis tool PlantSeg…

Expression   atlas   of Selaginella   moellendorffii   provides   insights   into   the evolution of vasculature, secondary metabolism, and roots (Plant Cell)

Lycophytes, including the model species Selaginella moellendorffii, are extant (still alive today) seedless vascular plants that were particularly abundant around 400-300 million years ago (and major contributors to the formation of coal). To further understand the biology of some of these oldest extant…

AuxSen: a biosensor for direct visualization of auxin (bioRxiv)

Auxins participate in nearly every aspect of plants' life cycle, but the information about the actual distribution of this hormone is scarce. The location of the hormone has been inferred using reporters based on auxin-transcriptional responses or auxin-dependent degradation signals. For a direct visualization,…

Review. Diatom molecular research comes of age:  Model species for studying phytoplankton biology and diversity (Plant Cell)

Diatoms are photosynthetic eukaryotes and contribute substantially to global carbon fixation. They are distantly related to green plants, having shared the same primary endosymbiotic event, although they subsequently underwent additional secondary endosymbioses. There are over 100,000 species of diatoms,…
