OpenAlex records 78 works, ~2,258 citations, and an h-index of 25 for NoemΓ Ruiz-LΓ³pez (ORCID 0000-0002-2169-0210), with citation peaks in 2012β2015 driven by metabolic-engineering work on omega-3 long-chain PUFA biosynthesis in transgenic Camelina and Arabidopsis . Since ~2019 her focus shifted to membrane contact site biology (synaptotagmins, E-Syts, SMP-domain proteins), spanning two career phases visible in the productivity curve below.
E-Syt stress mechanisms. A cross-kingdom study combining yeast cryo-FIB/cryo-ET (7 conditions, 7β22 tomograms each; EMDB EMD-57987β57995), plant cold-stress assays, and chimeric domain swaps shows E-Syt targeting needs an ER anchor + two C2 domains + SMP domain, and that SMP dimers set ERβPM distance (~27β29 nm across all conditions, minimal variation) and promote cortical ER peaks required for PM integrity . Notably, the authors explicitly report that cross-species SMP swaps rescue localization but not stress tolerance β an honest negative result that strengthens epistemic credibility. However, the ERβPM distance effect sizes are small (~1β1.5 nm differences, SEM 0.2β0.6), and the link between cER peaks and PM integrity is correlational, not causal.
NTMC2T5 discovery. A phylogenetically grounded, multi-method preprint identifies a new Archaeplastida-conserved SMP family at ERβchloroplast interfaces; CRISPR knockouts in two independent lines (plus complementation) show pale cotyledons, failure of de-etiolation, absent prolamellar bodies, ~80% MGDG and ~50% DGDG depletion, and elevated PE/PC/PI . Limitations the authors themselves flag: TEM only in line #14, no direct lipid-transfer or flux assays, and phenotypes largely restricted to early seedling development. Both studies declare no competing interests and use multi-institutional public funding (MICIU/AEI, DFG).
Known strengths: first-author landmark papers (361 and 94 citations), methodological breadth (metabolic engineering β cryo-ET β CRISPR lipidomics), transparent reporting of negative results (species-specific stress rescue, no lipid differences in dry seeds), deposited EMDB data, and statistical testing (two-way ANOVA + Dunnett). Blindspots: both 2026 works are preprints without peer review or incoming citations; SMP lipid-transfer activity β the mechanistic core of both claims β remains biochemically undemonstrated in vivo; small cryo-ET sample sizes (N=7β22); effect-size ranges are modest. What would change this assessment: peer review outcomes of both preprints and direct lipid-transfer assays for NTMC2T5/SMP dimers. Confidence: moderate-high for career metrics (OpenAlex), moderate for 2026 findings (unreviewed preprints).
