The Week in Botany October 13, 2025

A wreath being blessed for St John's Day.

I have my COVID vaccine, and my social battery badge, so I’m now ready for conferences. I have a naturally grumpy face so the battery badge is there to reassure people that I really am happy to talk to them. Unless it’s flashing red, in which case I’m probably heading to the exit.

This week I’m hoping to finish an article about plant names that I can use for reference in the future. Given my track record with deadlines, and things cropping up that take my attention, there’s a good chance I’ll miss the deadline. However, I make it public now, it should focus my mind on getting it out before the end of the month. To be honest, I don’t think I’ll have space to schedule this week as we have a lot in the system. For example, later today we have an article about a pollinator that might by unexpectedly important. Nonetheless it would be really hard to get people enthusiastic about saving it.

There will also be another email of the papers and the news stories you’re sharing on Mastodon and Bluesky at the same time next week. Until next time, take care.

Scientific Papers

Single Cell Multi-Omics Reveals Rare Biosynthetic Cell Types in the Medicinal Tree Camptotheca acuminata (FREE)
Camptotheca acuminata, a medicinal tree, produces camptothecin, a compound used in anticancer drugs. The biosynthesis of camptothecin involves complex steps, with the formation of strictosidinic acid catalysed by STR enzymes.

Choosing which models best explain photoperiodic time measurement mechanisms in plants (FREE)
Seasonal responses can be triggered by photoperiod changes. To explain photoperiodic time measurement, three main models (hourglass, external coincidence, and internal coincidence) have been proposed based on physiological observations in plants and animals. It has been discussed which model fits best to explain each response. Studies in model plants like Arabidopsis and rice suggest their photoperiodic mechanisms incorporate features that fit more than one of these models.

EPP1 is an ancestral component of the plant Common Symbiosis Pathway (FREE)
The success of plants on land has been enabled by mutualistic intracellular associations with microbes for 450 million years (Delaux and Schornack 2021). Because of their intracellular nature, the establishment of these interactions requires tight regulation by the host plants. In particular, three genes – SYMRK, CCaMK and CYCLOPS – form the core of an ancestral common symbiosis pathway (CSP) for intracellular symbioses, and are conserved since the most recent common ancestor of land plants (Radhakrishnan et al. 2020; Delaux et al. 2015; Wang et al. 2010; Parniske 2008). Rich et al describe EPP1 as a fourth gene committed to the CSP. Among land plants, EPP1 is conserved only in species able to associate with at least one type of intracellular symbiont.

KATANIN promotes cell elongation and division to generate proper cell numbers in maize organs (FREE)
Microtubule severing is essential for proper eukaryotic cell elongation and division. Here we show that the microtubule severing protein, KATANIN, is encoded by two genes in Zea mays (maize) called Discordia3a (Dcd3a) and Dcd3b. Loss of function allele combinations contribute to reduced microtubule severing and decreased cell elongation. The latter results in reduced cell number by slowing entry into mitosis. KATANIN is important for preprophase band (PPB) formation and positioning, and nuclear positioning in symmetric cell divisions. A combination of these defects contribute to generating mutant plants with small size and aberrant shape.

Engineered geminivirus replicons enable rapid in planta directed evolution ($)
Directed evolution can rapidly generate genetic variants with new and enhanced properties, yet efficient platforms for performing such evolution directly in plant cells have been lacking. Zhu et al developed Geminivirus Replicon-Assisted in Planta Directed Evolution (GRAPE), a system that links gene function to geminivirus rolling circle replication (RCR) to enable high-throughput selection for desired activities. GRAPE supports the screening of up to 105 variants on a single Nicotiana benthamiana leaf within four days.

MSL10 is a high-sensitivity mechanosensor in the tactile sense of the Venus flytrap (FREE)
The Venus flytrap (Dionaea muscipula), a carnivorous plant, possesses mechanosensitive organs called sensory hairs. After sensing a touch stimulus, the hair generates an action potential (AP) and a long-range calcium signal that propagate to the leaf blade, triggering leaf movement to catch prey after two successive calcium signals. Suda et al show that the MECHANOSENSITIVE CHANNEL OF SMALL CONDUCTANCE–LIKE homologue (DmMSL10/FLYC1) in the Venus flytrap acts as a high-sensitivity mechanosensor.

Beautiful and delicious mutants: The origins, fates, and benefits of molecular sequence variation in plant evolution and breeding (FREE)
Slewinski et al summarize specific examples of sequence variation that illustrate the extent and impact of plant mutation for agriculture and the essential value of mutational tools to generate additional useful genetic variation. Over time, these tools have been successfully deployed in plant breeding and have been accepted as a means to produce beneficial variation in crops without compromising safety.

Large-scale Phylogenomics Reveals Systematic Loss of Anthocyanin Biosynthesis Genes at the Family Level in Cucurbitaceae (FREE)
Choudhary et al investigated anthocyanin pigmentation in Cucurbitaceae, the second-largest fruit and vegetable family, characterised by white and yellow flowers and red, orange, and green fruits predominantly pigmented by carotenoids. Using a comprehensive collection of 258 datasets representing species across all 15 tribes of Cucurbitaceae and a phylogenomics approach, they observed a systematic absence of genes involved in anthocyanin and proanthocyanidin biosynthesis.

SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance ($)
Visualizing and quantifying the amount of a hormone within a cell can be achieved using fluorescence resonance energy transfer (FRET) sensors. These sensors involve a hormone binding to a pair of linked proteins, which then undergo conformational changes to alter the fluorescence emission ratio of two connected fluorescent proteins. Tang et al. have developed a FRET sensor for the plant hormone salicylic acid, which is primarily involved in activating immune responses.

Exploring fern pathosystems and immune receptors to bridge gaps in plant immunity (FREE)
Castel et al investigate fern-pathogen interactions by characterizing novel pathosystems and analyzing the diversity of fern immune receptors. A collection of fern species was inoculated with a diverse set of filamentous microbes, and disease symptoms were assessed. They further leveraged published genome mining tools to analyse the diversity of RECEPTOR-LIKE KINASES, RECEPTOR-LIKE PROTEINS(RLKs/RLPs) and NUCLEOTIDE-BINDING AND LEUCINE-RICH REPEATS (NLRs), along with key immune signalling components, in ferns.

The Bug-Network (BugNet): A Global Experimental Network Testing the Effects of Invertebrate Herbivores and Fungal Pathogens on Plant Communities and Ecosystem Function in Open Ecosystems (FREE)
Kempel et al introduce and report on the methodology of a novel global research network, The Bug-Network (BugNet), that implements standardized consumer-reduction experiments across 5 continents and 18 countries in diverse, herbaceous- or shrub-dominated ecosystems to investigate: (1) the influence of fungal pathogens, insect herbivores, and mollusks on plant diversity and ecosystem functioning, (2) interactions among these consumer groups, and (3) the abiotic and biotic drivers of context-dependent consumer impacts.
