Root system architecture (RSA) profoundly affects plant nutritent uptake and response to drought, and is also famously extremely developmental plastic, which makes it difficult to identify genes that control root growth traits. Here, Jiang et al. analyzed 3D growth patterns over time of three maize lines…

Uptake of water by plants depends on root conductivity, which in turn is determined by hydraulic properties of individual cells and cell anatomy. Quantification of radial root anatomy is a time-consuming process, limiting our understanding of root anatomical features contributing to water uptake. Heymans…

The leaf shape is one of the features defining the diversity in the plant kingdom. However, it is still not understood how action of individual genes is linked to this morphological diversity. Kierzkowski et al. developed an imaging protocol to study the leaf primodium development to understand the cellular…

Domestication has been accompanied by a decrease in genetic diversity, so efforts to improve stress tolerance can be aided by exploring the crop’s wild relatives. Here, Pailles et al. examined salt tolerance in Galapagos tomatoes (Solanum cheesmaniae and Solanum galapagense), which grow “constantly…

In this preprint Kim et al., have provided an optimized method for determining protein-protein interaction in plants using TurboID-mediated labelling.  TurboID is an engineered promiscuous biotin ligase that marks proteins it comes in contact with. Identification of interacting partners of a protein…

Barley leaf rust (Puccinia hordei) is a biotrophic fungus, in which mutations cause newly virulent races (pathothypes) with severe effects on cultivars. Marker-assisted Selection for Rph (Resistance to P. hordei) genes has been studied to provide sustainable control of this disease. Fazlikhani et al.…

Arsenic contamination is a growing human health threat. The fern Pteris vittata demonstrates a remarkable capacity to accumulate and sequester high levels of the toxic heavy metal arsenic from contaminated environments. Cai et al. used an ‘omics’-guided approach to identify and characterize the molecular…

Review: Integration of sulfate assimilation with C and N metabolism in transition from C3 to C4 photosynthesis “Cysteine (HO2CCH(NH2)CH2SH) synthesis is the converging point of the three major pathways of primary metabolism: carbon, nitrate, and sulfate assimilation.” These metabolic connections…
