Magnaporthe oryzae is the fungus that causes rice blast disease, which is a serious threat to food security. Ortiz et al. explore the interaction between AVR-Pia, a fungal effector protein, and RGA5, a rice NLR (nucleotide-binding domain and leucine-rich repeat protein) immune receptor protein. RGA5…

A seed undergoes a dramatic transformation from dried tissues into a mature plant.  This change requires energy produced by oxidative metabolism, but dry seeds contain dormant promitochondria that need to be reactivated.  Paszkiewicz et al. use bioimaging tools for an in vivo analysis of seed mitochondria…

Several studies have implicated microRNAs in plant defenses against pathogens. Wu et al. previously showed that virus resistance is facilitated by the interaction of viral-inducible AGO18 (which is cleavage-inactive) and rice miR528. In this work, they identified the role of miR528 in viral resistance.…

Students learn that membrane proteins are inserted into the endoplasmic-reticulum (ER) membrane co-translationally, but this mechanism does not hold for so-called tail-anchored (TA) proteins which carry a single C-terminal membrane spanning domain and insert into the ER membrane post-translationally.…

Nakamura et al. have created a searchable database, CATchUP (http://plantomics.mind.meiji.ac.jp/CATchUP) that allows the user to explore the spatiotemporal expression of genes across eight plant species (monocots and dicots) using data from publically available databases of large-scale RNA-Seq data.…

Efficient photosynthesis demands that plants have the capacity to capture photons when they are scarce, but at the same time not suffer damage from capturing more light energy than they are able to assimilate. To accomplish this, leaves need to be able to differentiate between a steady light level and…

Root architecture and anatomy contribute to water uptake efficiency and plant performance under water-limitation. Prince et al. explored root anatomy in a panel of soybean, and identified metaxylem number as a key trait influencing performance under water-limiting conditions. Increases in metaxylem number…

Understanding plant responses to water deficit is crucial for the development of drought-reliance, but complicated by the different ways plant researchers induce water deficit. Starting with the premise that transcription factors are important coordinators of water-deficit responses, Seeve et al. carried…
