Humic substances increase tomato tolerance to osmotic stress while modulating vertically transmitted endophytic bacterial communities.

While humic substances (HS) are recognized for their role in enhancing plant growth under abiotic stress by modulating hormonal and redox metabolisms, a key question remains: how do HS influence the microbiota associated with plants? This study hypothesizes that the effects of HS extend beyond plant physiology, impacting the plant-associated bacterial community. To explore this, we investigated the combined and individual impacts of HS and osmotic stress on tomato plant physiology and root endophytic communities. Tomatoes were grown within a sterile hydroponic system, which allowed the experiment to focus on seed-transmitted endophytic bacteria.

Principles, barriers and enablers to agroecological animal production systems: a qualitative approach based on five case studies.

Agroecology is among the most promising options to alleviate the negative impacts of animal farming on the environment and build local food systems based on ethically acceptable production methods. So far, most of the research on agroecological animal production systems was conducted at farm scale, and the potential of agroecological principles addressing social dimensions and food system-level approaches has been underexplored. Here, we analyse how the whole set of agroecological principles was mobilised in five case studies on grassland-based, silvopastoral or integrated crop-livestock systems in Switzerland, Guadeloupe, French uplands, Bulgaria and Andalucía.

Effect of kaolin on productivity, anatomical and biochemical responses to water deficit in Pelargonium graveolens grown in sandy soil.

The objective of this study was to examine the response of geranium plants to different irrigation levels (100%, 80%, and 60% based on ET) and Kaolin application rates (0, 100, 200 and 300 ppm) during 2022 and 2023 seasons, at Aly Mobarak Experimental Farm, Horticulture Research Station, located at El-Bustan site, El-Behiera Governorate, Egypt, by using a two-way factorial analysis experimental design. The results revealed that water deficit significantly reduced most studied traits. Irrigation level at 60% based on ET exhibited poorest performance on growth parameters and decreased fresh yield and essential oil yield by 27.

Metal phyto-accumulation potential, biochemical response, and health risk assessment of selected wheat varieties grown in municipal sewage sludge amended soils.

Present study identified metal accumulation potential, biochemical, growth, and human health risk attributes of wheat varieties (Zincol-16, NARC-09, NARC-11, Pakistan-13, Borlaug-16) cultivated in sewage sludge amended soils, that is, 80% soil + 20% sludge (C), 90% soil + 10% sludge (B) and 100% soil (control, A). Metal accumulation significantly varied ( < 0.05) among wheat varieties and the accretion pattern was roots > straw > grains.

A single NLR gene confers resistance to leaf and stripe rust in wheat.

Nucleotide-binding leucine-rich repeat (NLR) disease resistance genes typically confer resistance against races of a single pathogen. Here, we report that Yr87/Lr85, an NLR gene from Aegilops sharonensis and Aegilops longissima, confers resistance against both P. striiformis tritici (Pst) and Puccinia triticina (Pt) that cause stripe and leaf rust, respectively.

Molecular methods for the detection and identification of parasitoids within larval wheat midges.

Three species of cecidomyiid midges (Diptera: Cecidomyiidae) cause significant yield losses on wheat in Europe: Sitodiplosis mosellana (Géhin), Contarinia tritici (Kirby) and Haplodiplosis marginata (von Roser). Eggs and young larvae may be parasitised by a complex of hymenopteran parasitoids belonging to the Pteromalidae and Platygastridae families which contributes to natural pest control. We have developed molecular tools for detecting and identifying seven parasitoid species previously encountered in Belgium inside individual wheat midge larvae.

Comparative analysis of spectroscopic methods for rapid authentication of hazelnut cultivar and origin.

Hazelnut market prices fluctuate significantly based on cultivar and provenance, making them susceptible to counterfeiting. To develop an accurate authentication method, we compared the performances of three spectroscopic methods: near infrared (NIR), handheld near infrared (hNIR), and medium infrared (MIR), on over 300 samples from various origins, cultivars, and harvest years. Spectroscopic fingerprints were used to develop and externally validate PLS-DA classification models.

Linking stomatal size and density to water use efficiency and leaf carbon isotope ratio in juvenile and mature trees.

Water-use efficiency (WUE) is affected by multiple leaf traits, including stomatal morphology. However, the impact of stomatal morphology on WUE across different ontogenetic stages of tree species is not well-documented. Here, we investigated the relationship between stomatal morphology, intrinsic water-use efficiency (iWUE) and leaf carbon isotope ratio (δC).

Exploratory actor mapping of social interactions within tick risk surveillance networks in France.

Ticks are important zoonotic disease vectors for human and animal health worldwide. In Europe they are the principal vector of public health importance, responsible for Lyme disease, the most prevalent and widespread tick-borne disease (TBD). Tick presence and TBD incidence are increasing, questioning the effectiveness of existing surveillance systems.

DArTseq genotyping facilitates identification of Aegilops biuncialis chromatin introgressed into bread wheat Mv9kr1.

Wild wheat relative Aegilops biuncialis offers valuable traits for crop improvement through interspecific hybridization. However, gene transfer from Aegilops has been hampered by difficulties in detecting introgressed U- and M-genome chromatin in the wheat background at high resolution. The present study applied DArTseq technology to genotype two backcrossed populations (BC382, BC642) derived from crosses of wheat line Mv9kr1 with Ae.
