The Surprisingly Similar Glycomes of Maize and Arabidopsis Golgi
Research, The Plant Cell, The Plant Cell: In a NutshellOkekeogbu et al. compare the glycomes and proteomes of the Golgi in grasses and dicots, finding that the differences in cell wall architecture are not reflected in differences between polysaccharides produced in the Golgi. Plant Cell https://doi.org/10.1105/tpc.18.00755
Background: Grasses and other…
Getting to Know Each Cell in an Arabidopsis Root
Research, The Plant Cell, The Plant Cell: In a NutshellJean-Baptiste et al. use single-cell transcriptomic profiling to map developmental trajectories and assess cell-type specific changes during heat shock, demonstrating that single-cell transcriptomics holds promise for studying plant development and plant physiology at unprecedented resolution. Plant…
How Does Light Cause Arabidopsis Cotyledons to Open?
Research, The Plant Cell, The Plant Cell: In a NutshellDong et al. investigate cotyledon-specific light-regulated gene expression in Arabidopsis. The Plant Cell (2019). https://doi.org/10.1105/tpc.18.00803

Adaptive Loss-of-Function Mutations
Research, The Plant Cell, The Plant Cell: In a NutshellXu et al. study the effects of loss-of-function mutations in over 1000 Arabidopsis accessions. https://doi.org/10.1105/tpc.18.00321
By Yong-Chao Xu and Ya-Long Guo
Background: The gain of genes is thought to play important roles in the adaptation and diversification of plants. Loss-of-function…

Background: Abscisic acid (ABA) is a plant hormone that…
Digital imaging combined with genome-wide association mapping links loci to plant-pathogen interaction traits (Plant Phys.)
Plant Science Research WeeklyResistance to plant pathogens is often studied as a qualitative trait than quantitative, focusing on the lesion size and pathogen numbers. However, resistance to generalist plant pathogens, such as Botrytis cinerea, is known to involve multiple genes. Fordyce et al. used high-throughput phenotyping…
The xerobranching response represses lateral root formation when roots are not in contact with water (Curr. Biol. - $)
Plant Science Research WeeklyRoots navigate through the soil, foraging for water and nutrients. Orman-Ligeza et al. observed that lateral root development is repressed when the roots are growing through the soil air spaces. Exposure to water deficit induced transcriptome reprogramming in barley roots of genes involved in many hormone…
Complete substitution of a secondary cell wall with primary cell wall in Arabidopsis (Nature Plants - $)
Plant Science Research WeeklyPlant cell walls are important for terrestrial lifestyle, providing support and directing the plant growth. The primary and secondary cell walls differ in their chemical composition and flexibility. Secondary cell walls are less perceptive to industrial degradation processes and therefore pose problems…
