Assessing plant area index and 3D plant area distribution in wheat canopies from a terrestrial LiDAR system for high-throughput plant phenotyping

This study investigates a new methodology to estimate plant area index ( PAI ) and its spatial distribution from 3D point clouds acquired by a system of 3 LiDARs (2 nadir-viewing and one at 45°) mounted on the Phenomobile Unmanned Ground Vehicle designed for high-throughput pheno...

Sugar metabolism drives shoot branching by repressing BRC1 through miR319 –targeted TCP4 in Rosa

Abstract The coupling between sugar availability and shoot branching is well established, yet the underlying molecular mechanisms remain largely unknown. Here, using genome-wide profiling, we characterized the sugar signalling pathways by identifying 10 microRNAs (miRNAs) repress...

Monoclonal anti-dsRNA antibody-based metagenomics (MADAM) reveal Pyricularia oryzae mycovirome

This study introduces MADAM (Monoclonal Anti-dsRNA Antibody-Based Metagenomics), a novel approach that integrates multiple technical modules previously used independently in other protocols. MADAM combines monoclonal antibody-mediated double-stranded RNA (dsRNA) enrichment, seque...

OpenAlea.HydroRoot: A modelling framework to dissect, predict and phenotype branched root hydraulic architecture

Abstract Drought is a significant factor in agricultural losses, making it imperative to understand how root system architecture (RSA) adapts to environmental condition like water deficit. HydroRoot is a functional-structural plant model (FSPM) aimed at analyzing and simulating h...

Revealing archaeological olive diversity: insights from stone geometric morphometrics, experimental charring, and varietal identification (Port-la-Nautique, France, Roman period)

The cultivated olive tree, domesticated in the Levant by the mid-5th millennium BCE, spread westward across the Mediterranean to reach southern France by 600 BCE. Although geometric morphometrics applied to archaeological olive stones has provided insights into this diffusion, mo...

High uptake and adherence to cervical cancer screening among older French women based on a midwife-led outreach strategy and vaginal self-sampling: results from the RIDECA study

The acceptability and effectiveness of the invitation strategies using self-sample devices for cervical cancer screening are critical before further implementation. In France, participation of older women in cervical cancer screening remains low, and studies evaluating outreach s...

Empirical evidence for a trade-off between reproduction and tumour dynamics in the freshwater cnidarian Hydra oligactis

Abstract Reproduction is a key life-history trait but often comes at the expense of somatic maintenance, including ageing and susceptibility to disease. While reproduction–immunity trade-offs have been experimentally demonstrated in the context of infectious diseases, whether rep...

Candidate gene identification and molecular marker development for the small granule starch trait in cassava (Manihot esculenta Crantz)

Abstract Cassava ( Manihot esculenta ) is both a vital staple and industrial cash crop, with growing global demand for specialty starches. Small granule cassava starch is highly valued for industrial uses because its reduced size, high amylose content, and improved processing eff...
