An international team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne has shown that the Brazilian beak-sedge Rhynchospora tenuis reproduces sexually - producing pollen, fertilising its egg cells and sets seeds - but has completely lost the reshuffling of DNA between the chromosomes from each parent.

Plant cells grow and differentiate in an ever-changing environment characterized by transient signals and stimuli. The ability of plant cells to perceive, integrate, and dynamically respond to these stimuli underpins a plant adaptation and survival. Among the plethora of complex stimuli plant cells are exposed to, several stimuli have a mechanical component, for example, wind, touch, contact with insects, penetration of pathogens, and even intrinsic mechanical stresses arising during tissue growth. Despite the presence of a load-bearing cell wall that separates cells from the environment and fixes their location within a tissue, plant cells are responsive to mechanical stimuli. However, several questions remain unanswered around how mechanical stimuli are perceived and translated into cellular responses. Here we establish a system enabling application of quantifiable localized mechanical stress while simultaneously capturing cellular responses with high spatio-temporal resolution using confocal imaging. We show that this system enables estimation of locally applied pressure and provides access to the temporal and spatial details of subcellular events in intact living tissues upon touch. We propose that observing these subcellular events at high spatiotemporal resolution and linking their dynamics to the intensity of mechanical stimuli may uncover the molecular mechanisms underlying plant cell responses to touch. ### Competing Interest Statement The authors have declared no competing interest.

Welcome! Our research focuses on the evolutionary process at the molecular level. In particular, we investigate how a mixture of natural selection and non-adaptive forces create and maintain the amazing diversity in genome size, structure, and function that exists across the tree of life. Much of

DNA methylation is an important epigenetic mechanism involved in gene regulation. Most methods focus on analysing DNA methylation averaged from multiple reads, yet these average methylation profiles obscure heterogeneity between individual DNA molecules and coordinated methylation states across loci. Native Oxford Nanopore Technology (ONT) sequencing directly captures long, native DNA molecules together with their base modifications, allowing methylation to be studied at single-molecule resolution. Here, we present a scalable framework for genome-wide methylation analysis using ONT sequencing at single-molecule resolution, focused on two features that site-level summaries cannot recover. First, it quantifies molecule-to-molecule heterogeneity in DNA methylation by detecting Variable Methylated Domains (VMDs) and Variable Methylated Regions (VMRs). Second, it identifies coordinated methylation, as co-methylated positions (CMPs) and regions (CMRs), from the states observed on the same individual DNA molecules. Using data from human LCL cells, we demonstrate that substantial molecule-level methylation heterogeneity is masked by site-level summaries. Co-methylation analysis reveals coordinated patterns between CpG sites and genomic regions, including shared and sex-specific patterns, uncovering methylation organisation not apparent from average methylation levels. We also show that CMPs can be used to detect TF-pairs that are predicted to have coordinated binding. This framework is integrated within the DMRcaller R/Bioconductor package. ### Competing Interest Statement The authors have declared no competing interest.

To cause rice blast disease, the filamentous fungus Magnaporthe oryzae develops a specialised infection cell called an appressorium, which generates enormous turgor to breach the rice leaf cuticle. Although key regulators of appressorium development have been identified, it is not known how they drive the extensive transcriptional reprogramming required for infection-related morphogenesis. Here, we show that the Pmk1 MAP kinase orchestrates plant infection by regulating a transcriptional network controlled by the Mst12 and Bip1 transcription factors. Bip1 is regulated both by Pmk1-dependent phosphorylation and at the transcriptional level, while Mst12 binds to a cis-acting element upstream of BIP1 essential for pathogenesis. Bip1 and Mst12 are both necessary for regulating a set of Pmk1-dependent appressorium-specific genes, including transcriptional regulators, cell wall-degrading enzymes, and effector proteins. In addition, Mst12 specifically regulates functions required for appressorium-mediated penetration, while Bip1 controls a distinct sub-set of effector genes deployed during invasion of plant tissue. When considered together, these findings define a Pmk1-dependent transcriptional network required for plant infection by the blast fungus. ### Competing Interest Statement The authors have declared no competing interest.

Most organisms are well adapted to the environment they have been exposed to for many generations. However, changing environments pose existential threats to populations, unless they are able to adapt. Hence, a central challenge in evolutionary genetics is to understand the adaptation to complex environmental changes. As most traits are controlled by a large number of loci with varying effects on a trait, it is challenging to understand the explicit role of genetic changes during such polygenic adaptation. We use forward-in-time simulations to investigate the evolutionary dynamics of phenotypic and genetic adaptation in populations facing different environmental shifts. Specifically, we simulated sudden, gradual, and fluctuating environmental shifts for multiple trait architectures. Our results show distinct evolutionary paths across different types of environmental shifts and a higher extinction risk during sudden and fluctuating environmental shifts than during gradual shifts. Comparing the contribution of mutations from different sources highlights the critical role of standing genetic variation in driving phenotypic adaptation. We summarize allele frequency trajectories by clustering them by their temporal pattern and reveal how large- and small-effect mutations jointly shape the successful adaptation to changing environments. Additionally, we trained a convolutional neural network (CNN) on "genetic architecture matrices" of populations to jointly infer the type and magnitude of environmental changes and the mutational effect size distribution. The CNN was able to predict all three input parameters with very high accuracy, even on unseen parameter combinations. Our results demonstrate the impact of ecological change on the evolutionary outcome and the assorted mutational changes that enable successful adaptation. ### Competing Interest Statement The authors have declared no competing interest.
