Moises Exposito-Alonso named a member of the 2023 class of Forbes’ 30 Under 30 Europe list in science and healthcare

Out of the thousands of nominees, the 30 finalists in each of the 10 categories comprise “the world’s most impactful community of young entrepreneurs and game-changers,” said the publication in announcing his selection.  

“Growing up in southern Spain, I saw how Mediterranean forests may be transformed by climate change into arid deserts,” said Moi. “My childhood desire to halt this destructive trend manifested in a career pursuing the answers to fundamental questions about genetics, ecology, and evolution, which I believe are key to solving the global biodiversity crisis.”

Moi received his PhD at the end of 2018 for work on plant adaptation to climate change. Today, he leads a team at the Carnegie Institution that conducts large-scale ecological and genome sequencing experiments to generate maps of a species’ genomic susceptibility to climate change that may guide policymakers and management efforts in how to respond to this global challenge.   

Atypical Resistance Protein RPW8/HR Triggers Oligomerization of the NLR Immune Receptor RPP7 and Autoimmunity

Lei Li et al., Cell Host Microbe, published Feb 26, 2023. http://doi.org/10.1016/j.chom.2023.01.012

In certain plant hybrids, immunity signaling is initiated when immune components interact in the absence of a pathogen trigger. In Arabidopsis thaliana, such autoimmunity and cell death are linked to variants of the NLR RPP7 and the RPW8 proteins involved in broad-spectrum resistance. We uncover the molecular basis for this autoimmunity and demonstrate that a homolog of RPW8, HR4 Fei-0, can trigger the assembly of a higher-order RPP7 complex, with autoimmunity signaling as a consequence. HR4 Fei-0-mediated RPP7 oligomerization occurs via the RPP7 C-terminal leucine-rich repeat (LRR) domain and ATP-binding P-loop. RPP7 forms a higher-order complex only in the presence of HR4 Fei-0 and not with the standard HR4 variant, which is distinguished from HR4 Fei-0 by length variation in C-terminal repeats. Additionally, HR4 Fei-0 can independently form self-oligomers, which directly kill cells in an RPP7-independent manner. Our work provides evidence for a plant resistosome complex and the mechanisms by which RPW8/HR proteins trigger cell death.

The Earth BioGenome project: Opportunities and Challenges for Plant Genomics and Conservation

Sequencing them all. That is the ambitious goal of the recently launched Earth BioGenome Project (Lewin et al., 2018), which aims to produce reference genomes for all eukaryotic species within the next decade. In this Perspective, we discuss the opportunities of this project with a plant focus, but highlight also potential limitations. This includes the question of how to best capture all plant diversity, as the green taxon is one of the most complex clades in the tree of life, with over 300,000 species. For this, we highlight four key points: (1) the unique biological insights that could be gained from studying plants, (2) their apparent underrepresentation in sequencing efforts given the number of threatened species, (3) the necessity of phylogenomic methods that are aware of differences in genome complexity and quality, and (4) the accounting for within?species genetic diversity and the historical aspect of conservation genetics.
