The >1000 lipid species found in eukaryotic cells have vital functions. Using a combination of microscopy, spectroscopy and modelling, authors report @nature the first quantitative map of retrograde flux of individual lipids in cells.
nadlerlab.bsky.social
Out today in @nature.com: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism.

Plant NLR receptors mediate pathogen resistance, and so their engineering could lead to crops with broader pathogen specificity and so broader disease resistance. @nature, authors report one such attempt achieving resistance to several potyviruses. www.nature.com/articles/s41...

Remodelling autoactive NLRs for broad-spectrum immunity in plants - Nature
Cleavage by pathogen-derived proteases of an engineered chimeric protein activates its plant immune receptor component, enabling broad-spectrum resistance to pathogens in plants.

Very much looking forward to hearing and seeing exciting research and to interacting with reseachers at #2025ISMPMI. Happy also to answer any questions about publishing in Nature and sister journals.

How do plants notice loss of structural barriers (e.g. the periderm, which prevents water loss and pathogen infection) to regenerate them? Work @nature shows that plants sense damage to barrier integrity from diffusion of gases such as ethylene and oxygen. shorturl.at/FIhJ8
& N&V
shorturl.at/u7PYs
Injured plants use gaseous cues to initiate repair of their outer layers
The periderm layers of plants form an outer protective barrier. If the periderm is broken, movement of the gases ethylene and oxygen triggers a healing process.

A bottleneck for studying the biological function of biomolecular condensates is unavailability of tools to selectively probe them within living cells. @nature, researchers report one such tool, showcasing its use in various contexts including disease. www.nature.com/articles/s41...
Probing condensate microenvironments with a micropeptide killswitch - Nature
Targeting a non-natural micropeptide ‘killswitch’ to several biomolecular condensates altered condensate compositions and revealed condensate functions in human cells

The diverse cellular roles of early endosomes involve coordinated activity of several hundred integral membrane proteins and transiently associated regulatory complexes. A study @nature presents a systematic structural interactome of human endosomes . www.nature.com/articles/s41...
EndoMAP.v1 charts the structural landscape of human early endosome complexes - Nature
A study presents EndoMAP.v1, a resource that combines information on protein interactions and crosslink-supported structural predictions to map the interaction landscape of early endosomes.

Legume can form symbiotic relationship with some bacteria, while recognising others as pathogens. Work @nature identifies a plant kinase that mediates this nuanced balance of tolerance towards symbionts without compromised plant immunity. www.nature.com/articles/s41...

The technique of haploid induction creates homozygous plants, enabling faster breeding cycles. A paper @nature discovers a way of generating haploid sunflower, and optimises the approach for efficiency compatible with breeding programs for this important oilseed crop. rb.gy/vrqana & N&V rb.gy/e7uyep

While work @nature recently showed that the TIR1/AFB receptors of the plant hormone auxin have adenylate cyclase activity, further work now shows the broad physiological significance of this activity during plant development, via transcriptional reprogramming.

TIR1-produced cAMP as a second messenger in transcriptional auxin signalling - Nature
cAMP produced by the TIR1/AFB receptors of the main endogenous developmental plant hormone auxin acts as a true second messenger, revising the established paradigm of transcriptional auxin signalling.
