Plants have evolved to adapt to varied environmental niches. The ability to produce specialized metabolites is one of the evolved characteristics which help plants to thrive through varied biotic and abiotic conditions. Plant-associated microbes are always known to have a drastic impact on plant growth…

Calcium and chloroplasts are both at the heart of the signal transduction during environmental stress. Teardo et al. studied whether the chloroplast-localized mitochondrial calcium uniporter has a role in stress signaling. The group identified 6 homologs of mitochondrial calcium uniporter (MCU) in Arabidopsis,…

Wang et al. examine single-copy, conserved genes of unknown function, with OPENER as proof of concept. Plant Cell https://doi.org/10.1105/tpc.19.00033    By Wei Wang and Totte Niittylä, Umeå Plant Science Centre, Sweden  Background: Thale cress or Arabidopsis thaliana was the first sequenced…

Okekeogbu 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…

Dong et al. investigate cotyledon-specific light-regulated gene expression in Arabidopsis. The Plant Cell (2019). https://doi.org/10.1105/tpc.18.00803  By J. Dong, N. Sun, J. Yang, Z. Deng, J. Lan, G. Qin, H. He, X. W. Deng, V. F. Irish, H. Chen, and N. Wei Background: When germinating in darkness…

Yoshida et al. investigate how the phytohormone ABA balances normal growth and metabolism. https://doi.org/10.1105/tpc.18.00766. By Takuya Yoshida and Alisdair R. Fernie, Max-Planck-Institut für Molekulare Pflanzenphysiologie.   Background: Abscisic acid (ABA) is a plant hormone that…

Resistance 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…

Roots 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…
