In plants, immune signalling and the corresponding defence responses are initiated by direct or indirect recognition of pathogen molecules via immune receptors. In the plasma membrane, pattern-recognition-receptors (PRRs) recognize signs of invasion and pattern-triggered immunity (PTI) is initiated.…

Two very exciting papers have come out this week in Nature that address a long-standing question about the relative contributions of two different plant immunity pathways. PTI (pathogen-triggered immunity) recognizes conserved pathogen signatures at the plant cell surface; a model system for PTI is the…

If you regularly enjoy a cold glass of orange (Citrus × sinensis) juice, freshly squeezed or store-bought (who has time for the former, really?), then you should know that the future of this drink is at stake. Citrus greening disease or Huánglóngbìng (HLB) has been wreaking havoc on the citrus industry…

Arabidopsis (Arabidopsis thaliana) chloroplast-division mutants that have abnormally large chloroplasts have been around for quite some time, not only because they can be identified relatively easily through screening (Pyke & Leech 1991) and because their spectacular morphology sparks intrigue, but…

Rich-Griffin et al. uncover cell type-specific gene networks that function in plant immunity in Arabidopsis roots. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00154   By Charlotte Rich-Griffin1, Ruth Eichmann1,2, Sascha Ott3,4,5 & Patrick Schäfer1,2  1School of Life Sciences,…

Being a multicellular organism is not an easy task. Proper functioning of individual cell types with different functions requires coordination of gene expression to determine cell identity, but also regulatory mechanisms to respond to environmental cues. The root may appear simple at first sight, but…
