In today’s issue of @nature, read a Review article on the latest and upcoming technologies that could aid research and development in crop science, contributing to sustainable global food security. www.nature.com/articles/s41...

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... & shorturl.at/932j7

How the plant defence hormone salicylic acid (SA) is formed in some bacteria and in Arabidopsis is well-established. Three @nature papers now describe a different pathway of SA biosynthesis in non-Brassicaceae plants. rb.gy/9tgn8g shorturl.at/fYAYo shorturl.at/UCvo0 & NV tinyurl.com/bdz2p6dx

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

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...

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...

Want a taster of working as an editor? Nature has a locum position open for someone with interest in stem cell biology, developmental biology, and/or specific aspects of general cell biology. springernature.wd3.myworkdayjobs.com/SpringerNatu...

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 E3 ubiquitin ligase complex SIFI has a role in terminating stress response signalling, to restore cellular homeostasis. Researchers @nature present the cryo-EM structure of this ~1.3 MDa complex providing insights into its mechanism of action. www.nature.com/articles/s41...

Plant roots adapt to their environment including to soil conditions. Using single-cell transcriptomics, @nature authors report on the rice root responses and adaptations to soil-related stresses at individual cell level. www.nature.com/articles/s41...

At membrane contact sites, bridge-like transport proteins, e.g. LPD-3, mediate bulk lipid transfer between cellular organelles. @nature see cryo-EM structure of native LDP-3, and gain insights into its functioning and interaction with other proteins and lipids. shorturl.at/lycuz & shorturl.at/ARpUK

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

Proteins and nucleic acids move in and out of the nucleus through nuclear pore complexes (NPCs). Using 3D MINFLUX, @nature authors study single import and export events, gaining detailed insights into transport across NPCs within cells and at nanometer and millisecond scales. shorturl.at/2ClQp

Vector-borne viral pathogens are threats to crops, and so trigger plant immune responses. Studying rice, authors @nature provide molecular-level insights into the first steps of plant antiviral response. www.nature.com/articles/s41...

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. www.nature.com/articles/s41...

@nature, an extensive study, involving 18 KO and mutant mouse models, reveals why Parkin KO mice grow normally. It finds that the Parkin-mediated mitochondrial quality control works alongside another such pathway, involving Oma1. www.nature.com/articles/s41...

In plant immunity, activated sensor NLRs generate second messengers, which in turn activate helper NLRs such as NRG1. Two studies @nature use cryo-EM to provide mechanistic insights into NRG1 activation and inhibition. www.nature.com/articles/s41... & www.nature.com/articles/s41...

Initiation of symbiosis between legumes and nitrogen-fixing microorganisms involves Ca2+ oscillations in root cells. Work @nature provides insights into molecular fine-tuning of the Ca2+ oscillations, and show the transfer of this beneficial trait to wheat. www.nature.com/articles/s41...

How do cells recognise disease- and stress-affected proteins for clearance by ubiquitination? Work @nature shows that such proteins are marked with C-terminal amides, allowing their targeting by SCF/FBXO31 ubiquitin ligase for degradation. shorturl.at/B3rmR & NV shorturl.at/fImjA
