Nat Plants: Motif-based substrate mapping of the receptor-like cytoplasmic kinase BIK1 reveals novel components and regulatory nodes of plant immunity (2026) Plant cell surface pattern recognition receptors (PRRs) perceive non- or altered-self elicitors to induce immune responses. PRRs relay information across the plasma membrane and trigger downstream signalling via receptor-like cytoplasmic kinases such as BOTRYTIS-INDUCED KINASE 1 (BIK1). BIK1 associates with several PRRs and acts as a key executor of immune responses through the phosphorylation of substrate proteins. However, a comprehensive understanding of how BIK1 targets specific substrates and a full repertoire of these substrates are lacking. Here we defined the substrate specificity of BIK1 and used these data to predict candidate substrates in Arabidopsis. Using high-throughput biochemical and genetic screening of these candidates, we confirmed many as direct BIK1 substrates in vitro and novel regulators of plant immunity. Among the BIK1 substrates identified are MULTIPLE C2 DOMAIN AND TRANSMEMBRANE REGION PROTEIN 3, which we reveal regulates flagellin 22 (flg22)-induced plasmodesmata closure and immunity, and members of the largely uncharacterized CYCLIN-DEPENDENT KINASE-LIKE family, which we uncover as novel negative regulators of immunity. In parallel, we interrogated intracellular NUCLEOTIDE-BINDING LEUCINE-RICH REPEAT (NLR) immune receptors for potential BIK1 phosphorylation motifs and identified multiple NLRs as direct BIK1 substrates. We reveal that BIK1 phosphorylation regulates NLR oligomerization, thus controlling a key activation step for these immune receptors. Together, our unbiased biochemical screens shed light on the central role of BIK1 as a key kinase shaping multiple layers of plant immune signalling. Cell surface receptors perceive immunogenic elicitors, triggering downstream signalling via receptor-like cytoplasmic kinases such as BIK1. Here the authors define and use the phosphorylation motif of BIK1 to find novel substrate candidates.

bioRxiv: AMBER and GOLD: Polycistronic Genes for Betaxanthin Production in Plants (2026) Genetically encoded pigments are powerful visual reporters and creative tools for biology, yet in plants the palette of pigment biosynthesis genes has remained largely limited to red betacyanins encoded by RUBY. Here we develop and characterize three new polycistronic constructs AMBER_v1, AMBER_v2, and GOLD that contain betalain biosynthesis enzymes to produce yellow, fluorescent betaxanthins in plant tissues. These tools expand the palette of publicly available pigmentation genes for use in plant research, education, and floral design.

Happy to see this out! We describe a patterning mechanism underlying rhizoid specification in Marchantia. Contrary to classic patterning mechanisms (e.g., Turing), rhizoid specification depends on both randomness and lateral inhibition, involves subcritical bifurcations, and occurs at criticality!
