Sex without crossovers mimics clonal reproduction in Rhynchospora tenuis
Abstract Meiotic recombination ensures accurate chromosome segregation and promotes genetic diversity by generating crossovers between homologous chromosomes1. Although essential in most sexually reproducing organisms, recombination is variably regulated and can be absent in some lineages, a condition known as achiasmy2. However, obligate achiasmy in both sexes of a sexual species has not been documented.
Florigen activation complex forms via multifaceted assembly in Arabidopsis - Nature
Abstract Florigen, encoded by FT genes, is synthesized in leaves and transported to the shoot apical meristem (SAM) to induce flower development1,2,3. At the SAM, 14-3-3 proteins are proposed to act as receptors for FT protein and to mediate the indirect interaction between FT and the basic leucine zipper (bZIP) transcription factor FD to form the florigen activation complex (FAC) that activates transcription of flowering genes4,5,6.
Purifying recombinant proteins from Nicotiana benthamiana for structural studies - Nature Protocols
Abstract Structural biology is fundamental to understanding the molecular basis of biological processes. While machine learning-based protein structure prediction has advanced considerably, experimentally determined structures remain indispensable for guiding structure–function analyses and for improving predictive modeling.
Late Leaf Rust Monocyclic Components and Primary Metabolism of Raspberry Plants Facing Water Deficit
1 Introduction Climate change, characterised by shifts in rainfall patterns and rising global temperatures, has significant implications for agriculture (Ortiz-Bobea et al. 2021). It is associated with crop yield losses exceeding 50% in various agricultural regions (Zhao et al. 2017) and reductions in crop quality (Hýsek et al. 2017). In addition to these impacts, climate change is expected to affect pathogen virulence and disease development (Nnadi and Carter 2021; Velásquez et al. 2018).
A versatile protocol for purifying recombinant proteins from Nicotiana benthamiana for structural studies
Abstract Structural biology is an essential tool for understanding the molecular basis of biological processes. Although predicting protein structures by fold recognition algorithms has become increasingly powerful, especially with the integration of deep-learning approaches, experimentally resolved structures are indispensable for guiding structure-function studies and for improving modelling.
Will the euro area car sector recover?
The automotive industry contributes a significant share to the value added of the euro area economy. The share of the car industry in the manufacturing sector’s real value added amounts to 10% and the share in real GDP is slightly below 2%. The car industry accounts for 1% of total euro area employment and 4% of extra-euro area exports. When inter-sectoral linkages are taken into account, the value added almost doubles, highlighting the sector’s extensive reach within the economy.

The development of pleiotropic phenotypes in powdery mildew‐resistant barley and Arabidopsis thaliana mlo mutants is linked to nitrogen availability
BSA bovine serum albumin flg22 22-amino acid elicitor epitope of bacterial flagellin Mlo mildew resistance locus o SA salicylic acid 1 INTRODUCTION Plant MLO genes encode integral membrane proteins that were recently found to operate as cation channels (Gao et al., 2022, 2023).
Amphicarpic development in the emerging model organism Cardamine chenopodiifolia
Abstract - Amphicarpy is an unusual trait where two fruit types develop: one above and the other below ground. This trait is not found in conventional model species, therefore, its development and molecular genetics remain under-studied. Here, we establish Cardamine chenopodiifolia as an emerging experimental system to study amphicarpy. - We characterized the development of C. chenopodiifolia, focusing on differences in morphology and cell wall histochemistry between above- and below-ground fruit.
Apoplastic barrier establishment in roots and nodules of Lotus japonicus is essential for root-shoot signaling and N-fixation
Abstract The molecular framework underlying apoplastic root barrier formation has been unveiled in the model species Arabidopsis thaliana where establishment of Casparian strips occurs at an early stage of root development. In legumes, this region overlaps with the area where nitrogen-fixing bacteria can induce nodule formation, termed the susceptible zone.

Auxin boosts energy generation pathways to fuel pollen maturation in barley
Highlights • Barley pollen autonomously produces high auxin levels to control its maturation • The cereal-specific enzyme HvYUCCA4 synthesizes bioactive auxin in barley pollen • Auxin is required to enhance the expression of central carbon metabolism genes • Increased flux of energy production pathways fuels pollen starch accumulation Summary Pollen grains become increasingly independent of the mother plant as they reach maturity through poorly understood developmental programs.
