Genomic selection is an extension of marker-assisted selection by leveraging thousands of molecular markers distributed across the genome to capture the maximum possible proportion of the genetic variance underlying complex traits. In this study, genomic prediction models were developed by integrating phenological, physiological, and high-throughput phenotyping traits to predict grain yield in bread wheat (Triticum aestivum L.) under three environmental conditions: irrigation, drought stress, and terminal heat stress.

Background: Crop wild relatives (CWR) represent a valuable resource for ensuring food security. Although they are negatively affected by the loss of habitats due to climate change and land use change, they are underrepresented in conservation programmes. The establishment of genetic reserve (GR) networks has been put forward as an approach to protect CWR.

Background And Aims: In perennial crops, efficient resource acquisition critically depends on whole-plant architecture, encompassing both canopy and root systems. In grafted grapevine, research has largely focused on scion canopy structure, whereas root system architecture - despite its key role in water and nutrient uptake - remains underexplored. This study comprehensively analyzed whole-plant 3D architecture during vineyard establishment, investigating how different rootstock genotypes influence both root and shoot development.

Multiparent populations are now widespread in crop genetic studies as they capture more genetic diversity and offer high statistical power for detecting quantitative trait loci (QTLs). To confirm the suitability of using a recently developed chickpea (Cicer arietinum L.) multi-parent advanced generation intercross (MAGIC) population for genetic studies, we characterized the diversity of the eight founder lines and explored the linkage disequilibrium decay, marker coverage, segregation distortion, allelic variation, and structure of the population.

Queensland Alliance for Agriculture and Food Innovation, The University of Queensland, Brisbane, Queensland, Australia.

Root system architecture (RSA) plays a crucial role in crop adaptation and yield stability, especially in the context of climate change and variable growing conditions. Despite this, the genetic basis of RSA remains poorly understood in barley (Hordeum vulgare L.), necessitating the need for more research to better characterize this architecture and explore the potential of diverse germplasm for trait improvement.

The genetic diversity of Fragaria species in situ has great potential for breeding resistance in cultivated strawberries against anthracnose disease. In this study, we investigated the host-pathogen interactions of 72 F. vesca genotypes of various German origins to identify new resistance to Colletotrichum, one of the most economically important genera of pathogens in F.

Grapevine has been clonally propagated for thousands of years. Though clonal propagation aims at maintaining varietal identity, somatic mutations and epigenetic modifications accumulated over hundreds to thousands of years lead to intra-varietal diversity. This intra-varietal variation is a very valuable resource in grapevine breeding, as it creates the opportunity to improve important traits related to yield, phenology, stress tolerance, and quality without altering the varietal identity which is extremely important for the industry.

The micronutrient chloride (Cl) plays key roles in plant physiology, from photosystem II and vacuolar ATPase activity to osmoregulation, turgor maintenance and drought resilience, while also posing toxicity risks at high concentrations. This review examines Cl uptake, transport and homeostasis, focussing on adaptations balancing its dual roles as a nutrient and toxicant. Key transporters, including NPF, SLAH, ALMT, CLC and CCC families, mediate Cl fluxes to maintain ionic balance and prevent toxicity.

Carbon dioxide removal plays an important role in any strategy to limit global warming to well below 2 °C. Keeping abreast with the scientific evidence using rigorous evidence synthesis methods is an important prerequisite for sustainably scaling these methods. Here, we use artificial intelligence to provide a comprehensive systematic map of carbon dioxide removal research.

Molecular mechanisms underlying the early steps of floral initiation in seasonal flowering genotypes of cultivated strawberry.

Forschungszentrum Jülich, Institute of Bio- and Geosciences, Institute for Bio- and Geosciences (IBG)-4 Bioinformatics, Bioeconomy Science Center (BioSC), Jülich, Germany.

Floral initiation is essential for sexual reproduction in angiosperms and plays a critical role in determining crop yields. In cultivated strawberry, however, the molecular mechanisms underlying floral initiation remain poorly understood, with most studies focusing on a single genotype under controlled conditions. To gain more insight into this process, we conducted a field-based study in two countries using two seasonal flowering cultivars.

Improving crop root systems for enhanced adaptation and productivity remains challenging due to limitations in scalable non-destructive phenotyping approaches, inconsistent translation of root phenotypes from controlled environments to the field and a lack of understanding of genetic controls. This study serves as a proof of concept, evaluating a panel of Australian barley breeding lines and cultivars in field experiments conducted across two contrasting environments. A diverse subset of 20 genotypes was subjected to ground-based root and shoot phenotyping at key growth stages and this dataset was used in combination with UAV-captured vegetation indices (VIs) to train machine learning models to predict root distribution and above-ground biomass for the untested panel comprising 544 genotypes across the two seasons.

Background: Field inoculation of crops with beneficial microbes is a promising sustainable strategy to enhance plant fitness and nutrient acquisition. However, effectiveness can vary due to environmental factors, microbial competition, and methodological challenges, while their precise modes of action remain uncertain. This underscores the need for further research to optimize inoculation strategies for consistent agricultural benefits.

Ivermectin, an anthelmintic used in livestock, is excreted in faeces and can therefore affect non-target organisms. While its effects on coprophagous insects have been well studied, recent research suggests that it can be taken up by plants, raising the possibility that it may affect a much wider range of invertebrates than previously known. Our study investigated the effects of ivermectin on insects from different feeding guilds.

The reproductive performance of wild bees is a key determinant of their population persistence. However, few studies have directly examined the environmental drivers of demographic processes using a geographically broad approach. In this study, we explored how biotic and abiotic factors influence the reproduction of solitary, cavity-nesting bees across the Monte Desert ecoregion in Argentina.

'Timorasso' is an autochthonous, non-aromatic white grape variety cultivated mainly in the southwest of the Piedmont region (northwestern Italy). The sensory profile of wines produced from this variety evolves greatly with aging. In this study, 31 wines from 2015-2021 vintages were analyzed to investigate changes in sensory descriptors at various stages of aging and their correlation with physicochemical properties (wine basic parameters, color, and total polyphenols) and sensory-perceptual typicity.

Application of cryo-FIB-SEM for investigating ultrastructure in guard cells of higher plants.

Plant Physiol Biochem

March 2025

Institute of Crop Science, Quality of Plant Products (340e), University of Hohenheim, Emil-Wolff- Straße 25, 70599, Stuttgart, Germany.

Stomata are vital for CO and water vapor exchange, with guard cells' aperture and ultrastructure highly responsive to environmental cues. However, traditional methods for studying guard cell ultrastructure, which rely on chemical fixation and embedding, often distort cell morphology and compromise membrane integrity. In contrast, plunge-freezing in liquid ethane rapidly preserves cells in a near-native vitreous state for cryogenic electron microscopy.
