I try to follow what you're sharing on Mastodon and Bluesky each week, to pick the top botany links, but it's getting more difficult. Usually, when something dominates the news, the news links disappear but the scientific papers continue getting shared. The Epstein War is proving different. I can't tell yet if fewer papers are being shared, or if the distribution has broadened, making fewer obvious peaks. I've worked out a solution which seemed simple enough till I realised it would mean building a mini-Altmetric.

Something I made this week, which might stay around or get deleted is the Species Dashboard. If you want to know about a species, you can type a name into the search box, and you'll get results. These are an overview from Wikipedia, some taxonomy links from IPNI and others, something on the phyologeny, species records from professionals, observations from citizen scientists and the latest research on the species from OpenAlex. So this is how I got information about Tulipa cypria this week. Before I used it, all I knew about Tulipa cypria is that there was a nice photo that would look good for plant of the week.

I notice that following the appearance of the Bosnian Lily on the site last week as the cover image, Bosnia & Herzegovina have gone on to knock Italy out of the World Cup and qualify for the finals. If anyone wants to give their team a boost in June, then I want to let you know that I am bribable, but only in gold bullion in these uncertain times.

If a large amount of gold doesn't arrive on my doorstep in the coming week, then there'll be another issue of The Week in Botany, at the usual time. Until then, take care.

When I was a postdoc, one of the job interviews I did involved both a research seminar and a teaching lecture (given to members of the department, not an actual class). I prepared a lecture on community ecology and practiced it in front of lab folks. After it, my postdoc advisor, Tony Ives, gave me advice that I still think of often: the art of teaching is learning how to selectively lie.

Scientific Papers

Emily Fairfax, Cherie Westbrook
Beavers, Castor canadensis in North America and Castor fiber in Eurasia, are widely referred to as nature's engineers due to their ability to rapidly transform diverse landscapes into dynamic wetland ecosystems. As we follow an unprecedented trajectory of anthropogenic warming, we have the unique opportunity to describe how beaver ecosystem engineering ameliorates climate change today. Here, we review how beavers create and maintain local hydroclimatic stability and influence larger-scale biophysical ecosystem processes in the context of past, present, and future climate change.
Annual Review of Ecology, Evolution, and Systematics (November 2024)
In this review, we outline the current body of knowledge on how the embryo, endosperm, and seed coat communicate with one another during the early stages of seed development. We also discuss the nature and variability of signalling mechanisms across these tissues and the impact of these interactions on seed development and associated agronomic traits, highlighting how understanding these communication pathways can contribute to agricultural biotechnology.
Journal of Experimental Botany (March 2026)
In this work, we uncover temperature-regulated accumulation and solubility of members of the AUXIN RESPONSE FACTOR transcription factor family. We determine that ARF7 and ARF19 proteins rapidly hyperaccumulate in response to elevated temperature. Furthermore, we find that diffuse concentrations of ARF protein increase under elevated temperature, consistent with increased solubility.
Nature Communications (March 2026)

Here we compile the chromatin toolkit of brown algae and show that canonical silencing systems involving DNA cytosine methylation and Polycomb repressive complex 2 (PRC2)-mediated histone H3 lysine 27 (H3K27) methylation were lost early in their evolution. By generating hPTM profiles from diverse brown algal clades, we resolve the nature and regulatory roles of chromatin states in this lineage and show how H3 lysine 79 (H3K79) methylation emerged and diversified as a repressive system.
Nature Ecology & Evolution (March 2026)
Although color and scent are well-established pollination signals, some plants also produce heat. Valencia-Montoya et al. discovered that plant-produced heat is an early pollination signal and describe the molecular basis of both heat generation in cycads and heat sensing in beetle antennae.
Science (December 2025)
Here, we discovered defense-related membrane contact sites (MCS) comprising a membrane tethering complex between chloroplasts and the extrahaustorial membrane (EHM) surrounding the haustorium of the pathogen Phytophthora infestans in Nicotiana benthamiana. The assembly of this complex involves association between the chloroplast outer envelope protein CHLOROPLAST UNUSUAL POSITIONING 1 (CHUP1) and its plasma membrane-associated partner KINESIN-LIKE PROTEIN FOR ACTIN-BASED CHLOROPLAST MOVEMENT 1 (KAC1). Our biochemical assays revealed that CHUP1 and KAC1 interact, and infection cell biology assays demonstrated their co-accumulation in foci where chloroplasts contact the EHM.

Here, we report our development of the Multi Targeted AmiRNA Cell type–specific Transportome-scale (mTACT) toolbox, which can be used to reveal phenotypic plasticity in plants. mTACT is based on a large set of artificial microRNAs (amiRNAs), each designed to optimally target multiple members of a particular gene family encoding transporter proteins. In total, the mTACT toolbox includes 5,565 amiRNAs, targeting 81.7% of the Arabidopsis (Arabidopsis thaliana) transportome.
Plant Physiology (February 2026)
Unlike Arabidopsis, Nicotiana benthamiana uses the SENESCENCE ASSOCIATED GENE 101– N REQUIREMENT GENE 1 branch of TIR signaling to activate salicylic acid biosynthesis, illustrating evolutionary divergence in how conserved immune signaling modules are deployed to control salicylic acid production across plant lineages.

Here we report that the β subunit of SnRK1, SnRK1β1A, confers broad-spectrum susceptibility to these fungal diseases. Our findings show that diverse rice fungal pathogens have convergently evolved an effector-like protein, Gas2, which interacts with SnRK1β1A to prevent its ubiquitination-mediated degradation and promotes its nuclear translocation.

We show that warming produces compound- and species-specific changes in floral VOC emissions, affecting both the composition and emission rates of compounds that may influence pollinator attraction. We also identify key knowledge gaps and research priorities, including the need to integrate floral chemistry, plant flowering phenology, and pollinator sensory ecology to better understand the stability of plant–pollinator interactions under climate warming in the tropics.
Annals of Botany (March 2026)
Plants in ex situ conservation nurseries acquire diverse fungal associates that may be moved among nurseries or into the wild during outplanting, including fungal endophytes that contribute to a broad range of functions and occur in leaves, sometimes alongside pathogens. To improve understanding of fungal symbionts in a plant of high conservation concern, we characterized foliar fungal endophytes of Torreya taxifolia, one of the world's most threatened conifers, in an ex situ conservation nursery.

In the project to which this role will contribute, we will characterise plant genetic mechanisms that coordinate the interaction of mycorrhizal fungi with plant P and water status, the development of the root system, and the broader community of soil microbes. With partners at Cambridge University, and in Germany and the US, we will work from the scale of the single gene to field evaluation to define a framework for rational optimisation of plant-mycorrhizal symbioses for more efficient P use in agriculture. The modelling component will involve combining existing models of root system growth, rhizosphere processes and P uptake developed by the project partners and developing new models of the effects and costs of mycorrhizal symbioses.
