Editorial. Counting what counts: quantitative approaches in plant cell biology (COPB)

In the new Cell Biology issue of Current Opinion in Plant Biology, editors Haswell and Dixit have chosen to focus on quantitative cell biology, arguing that, “if seeing is believing, then measuring is knowing.” Topics of the issue’s reviews span parts of the cell (including cell wall, cytoskeleton, stromules), things cells do (including morphogenesis) and […]

Review. Of mice and plants: Comparative developmental systems biology ($) (Devel Biol.)

Although mulicellularity, and so also development, evolved independently in animals and plants, there are nevertheless some striking parallels in the mechanisms used to coordinate these processes. Ten Tesschur compares four developmental processes in plants to similar processes that occur in animal development. As examples, root growth and lateral root prepatterning is compared to body axis […]

Review: Perspective on wheat yield and quality with reduced N supply (TIPS)

Wheat production demands huge inputs of nitrogen as fertilizer, with accompanying financial and environmental costs. Zorb et al. discuss several strategies by which to maintain wheat yields and wheat quality while decreasing N use and wastage. Some of these are agronomic, such as ensuring that the N applications occur at times that are optimal for […]

POLAR-guided signalling complex assembly and localization drive asymmetric cell division (Nature)

In Arabidopsis, stomatal guard cells are specified following a set of conserved asymmetric cell divisions (ACDs), starting with a meristemoid mother cell. How do cells establish asymmetric divisions? Several proteins have been identified that are required for this, including BASL and POLAR, transcription factors including SPCH, as well as BIN2 and MAP kinases. BIN2 has […]

Archetypal roles of an ABA receptor in drought and sugar responses in liverworts ($) (Plant Physiol)

Much of our understanding of the molecular pathway for ABA response comes from studies on Arabidopsis. Thanks to genomic sequencing efforts, we know that this pathway is largely conserved amongst plants, including mosses. Jahan et al. extend this understanding to liverworts, drawing on the recently sequenced genome of Marchantia polymorpha. They identified five proteins as […]

Genetic dissection of Fe-dependent signaling in root developmental responses to phosphate deficiency ($)

Phosphate deficiency leads to arrest of primary root elongation. Previous work has shown that this arrest depends upon Fe, raising the possibility that Fe accumulation in the root apex is the cause of growth arrest. Several genes involved in low Pi response have been identified, including genes encoding the LPR1 ferroxidase, ALS3/STAR1 transporter complex and […]

Plant extracellular vesicles contain diverse small RNA species and are enriched in 10-17 nucleotide “tiny” RNAs (bioRxiv)

Small RNAs are known to move between cells and even between organisms. Studies in mammals have shown that extracellular vesicles (EVs) can contribute to small RNA transport, and recently small-RNA containing EVs were identified in plants. Baldrich et al. extend this work with an analysis of the types of small RNAs contained in plant EVs. […]
