1. The controls that got out of control
Schneider, A. · EMBO Reports · Score: 388

How would you define science to a lay person, considering that ‘science’ includes highly diverse disciplines? My answer would be that all these disciplines share a common foundation, called the ‘scientific method’. It provides a universally valid framework, enabling anyone, regardless of scientific or cultural background, to arrive at the same conclusions when analyzing the same data. Unlike faith, which is highly subjective, the scientific method offers an objective, systematic approach to uncover facts about the natural world.

'If a control experiment fails, does that mean that the entire experiment is poorly designed and you must restart from scratch? Often, yes— but not always. I present five examples where failed control experiments triggered entirely new fields of research.' link.springer.com/article/10.1...

2. Melatonin seed priming: A climate‐smart, green strategy to enhance abiotic stress tolerance in plants
Raza, A. et al. · Journal of Integrative Plant Biology · Score: 326

Enhancing crop tolerance to multiple abiotic stresses is critical for achieving sustainable agriculture. Targeted seed‐stage interventions using natural signaling compounds (e.g., melatonin) provide a unique opportunity to establish early stress tolerance that can persist through the critical seed‐to‐seedling transition. Melatonin seed priming (MSP) is rapidly emerging as a green and climate‐smart strategy for enhancing plant stress tolerance. MSP triggers defensive molecular, biochemical, and physiological reprogramming during germination, thereby improving plant performance under subsequent stress conditions. This review synthesizes recent mechanistic insights into how MSP confers stress tolerance across diverse species by modulating redox signaling, hormonal homeostasis, and stress‐related gene networks.

3. Anticipate, acclimate, recuperate and remember: How spatiotemporal signal integration controls flooding stress resilience in plants 💰
Rodriguez-Cisneros, C. et al. · Journal of Experimental Botany · Score: 286

Flooding is a major abiotic stress that restricts terrestrial plant growth and survival. A plant tissue’s ability to avoid or sustain critical oxygen deprivation (hypoxia) and subsequent re-oxygenation damage is vital for its survival. Submergence triggers rapid ethylene and hypoxia signalling that in turn control acclimation responses, promoting plant resilience. Interestingly, an extensive range of additional environmental and internal factors were shown to influence these canonical signalling pathways associated with flooding acclimation and tolerance. Here, we discuss how such integrative ethylene- and hypoxia-dependent signalling enables plants to anticipate and prepare for potential flooding-induced hypoxia stress, fine-tune acclimation according to the environmental and internal metabolic context, and effectively orchestrate re-oxygenation responses.

Excited to see our #plantscience review published in @jxbotany.bsky.social! It really captures our lab’s perspective on how plants use spatiotemporal signaling under environmental contexts when floods occur, to coordinate acclimation responses and achieve stress tolerance. doi.org/10.1093/jxb/...

4. Harmala alkaloids regulate cell division planes in plants
Diehl, K. A. et al. · bioRxiv · Score: 238

Here, we investigated the effects of the harmala alkaloids on plant growth and cell division using Arabidopsis thaliana as a model system. Of the harmala alkaloids, harmaline was identified as the most potent compound for root growth inhibition. Quantitative live cell imaging demonstrated that harmaline exposure causes progressive defects in cell division orientation and root cell morphology in a temporal manner.

(1/11) Excited to share the brand-new cell division preprint from the lab! In this manuscript, chemical biology (in a collaboration with @rnett42.bsky.social Ryan’s lab) meets the cell biology (our lab). Harmala alkaloids regulate cell division planes in plants www.biorxiv.org/content/10.6...

5. Molecular mimicry of a pathogen virulence target by a plant immune receptor 💰
Gómez De La Cruz, D. et al. · Science · Score: 200

Plants and animals respond to pathogen attack by mounting innate immune responses that require intracellular nucleotide-binding leucine-rich repeat (NLR) proteins. These immune receptors detect pathogen infection by sensing virulence effector proteins. However, how receptors evolve new recognition specificities remains poorly understood. We found that the plant NLR MLA3 (Mildew locus a 3) has evolved to recognize a pathogen effector by acting as a molecular mimic of an effector virulence target, thereby triggering an immune response.

So proud to see this story finally out!🎉 We added new data since our previous preprint—transgenic barley plants with an engineered immune receptor that fights off two fungal pathogens at once. Short 🧵 and link to the original preprint thread on X👇 www.science.org/doi/10.1126/...

6. A membrane-anchored inhibitor of papain-like cysteine proteases promotes Pseudomonas root colonization
Moser, D. et al. · bioRxiv · Score: 192

Pseudomonas species, spanning both beneficial and pathogenic lifestyles, possess conserved mechanisms to modulate plant immunity. Nevertheless, the mechanisms by which commensal bacteria establish and maintain host colonization remain poorly understood. Here, we report the characterization of a Pseudomonas chagasin-like protease inhibitor (Cpi1), conserved across pseudomonads representing a novel class of membrane-anchored PLCP inhibitor. Unlike previously described secreted protease inhibitors, P. putida Cpi1 is a lipoprotein localized to the bacterial surface and outer membrane vesicles (OMVs), positioning it to selectively inhibit immune-related papain-like cysteine proteases (PLCPs) during host interactions.

📢 new preprint! How do commensal bacteria establish themselves on plant roots despite plant immunity? We identify Cpi1, a conserved membrane-anchored protease inhibitor in Pseudomonas that promotes early root colonization and modulates microbial community assembly. www.biorxiv.org/cgi/content/...

7. The demonstration of a single origin for nodule evolution, with nodule engineering in a non-nodulating species
Kundu, A. et al. · Score: 176

The nitrogen-fixing root-nodule symbiosis provides a sustainable source of nitrogen for plants within the Nitrogen (N)-fixing clade (NFC). A debate has raged over whether nodulation evolved once, with many losses or multiple times following a predisposition event. Here we demonstrate that nodule-organogenesis is fully conserved between an actinorhizal nodulator Datisca glomerata and the legume Medicago truncatula, showing entirely conserved programmes for Nodule INception (NIN)-controlled development leading to nodule emergence.

8. An active Helitron transposon family in wheat
Peng, H. et al. · Nature Plants · Score: 176

Transposable elements play a pivotal role in genome evolution and phenotypic variation in numerous eukaryotic species. Helitrons, a recently identified category of transposons, remain poorly understood in terms of epigenetic regulation and real-time mobilization in plants. Here our study reveals that reduced DNA methylation combined with heat stress promotes the mobilization of the Xuan–Feng Helitron family in wheat.

We just published our new paper about an active Helitron transposon in wheat 🌾🧬 We found that it can be mobilised by heat stress when DNA methylation is reduced. We document its full lifecycle: RNA -> circular DNA -> integration www.nature.com/articles/s41... #TEsky

8. Synchronous spatiotemporal control of autophagy and organelle trafficking is necessary for infection by Magnaporthe oryzae
Eseola. A.B. et al. · Cell Reports · Score: 174

The blast fungus Magnaporthe oryzae infects plants using an appressorium that generates force to breach the leaf cuticle. Appressorium development follows a cell-cycle-regulated morphogenetic program requiring autophagy-associated death of the spore. How proliferative growth is coordinated with cell death remains unclear. Here, we show that each conidial cell follows a distinct developmental program essential for infection.

Peer-reviewed version of our study led by @aliceeseola.bsky.social first seen on @biorxiv-cellbio.bsky.social showing the exquisite level of control of organelle trafficking & autophagy exerted during plant infection by the blast fungus. Thanks to all co-authors. www.cell.com/cell-reports...

10. TALEs, TALENs, and TALE Base Editors: From Plant Pathology to Biotechnology 💰
Grau, J., Boch, J. · Annual Review of Phytopathology · Score: 138

TALEs (transcription activator-like effectors) are an excellent example of how studying pathogen–host interactions can lead to significant biotechnology inventions. TALEs are bacterial effectors that are translocated into plant cells via a bacterial type III secretion system. We review recent advances in Xanthomonas genomics, synthesize current knowledge about naturally occurring TALEs, and highlight current roles of TALEs in genome editing and synthetic biology.

It's be an honour to write this TALE-review with my long-time friend and colleague Jan Grau 👨‍🔬📗🧑‍💻. It's about both worlds: virulence, genomics 🌾🧫🧪 & genome editing, SynBio 🧬✂️. All figures done by ourselves! Hope you like it. Please spread the news! 📰🥳 doi.org/10.1146/annu...
