Summary: Sorghum bicolor is an important cereal crop in Ethiopia, but its productivity is hindered by drought. This study assessed the genetic variability of 214 sorghum genotypes for root and shoot traits, finding that Ethiopian Biodiversity and ICRISAT genotypes displayed more genetic diversity in root system architecture traits. Phenotypic and genotypic coefficient variations varied among traits, with broad sense heritability ranging from 40% to 94.18%. The findings can help identify promising genotypes with suitable root traits for potential breeding under specific environmental conditions.

Summary: Recent developments in low-cost imaging hyperspectral cameras have opened up new possibilities for high-throughput phenotyping. This study integrated a low-cost hyperspectral camera into an HTP platform to evaluate the drought stress resistance and physiological response of four tomato genotypes. The study collected over 120 gigabytes of hyperspectral data and developed an innovative segmentation method to reduce the dataset. The results showed the better capacity of the hyperspectral index to describe the dynamic of drought stress trend compared to optical indices, while the selected optical indices were capable of describing structural changes during plant growth.

Summary: Interannual and local fluctuations in wheat crop yield are primarily influenced by abiotic constraints such as heatwaves and drought. This study aimed to identify phenotypic traits that contribute to adaptive stress responses in wheat under water deficit and high temperature conditions. High-throughput methods were used to phenotype 10 wheat genotypes, and regression machine learning models successfully predicted plant biomass based on image-extracted parameters. The study highlights the importance of transpiration efficiency and the interplay between carbohydrate metabolism and antioxidant metabolism in wheat's stress tolerance. The observed genetic differences can be utilized in breeding programs to enhance wheat resilience to climate change.

Summary: Quinoa is a genetically diverse crop that can tolerate abiotic stresses and has gained popularity due to its high nutritional content. The coastal lowland ecotype of quinoa is of interest for cultivation in higher latitudes. A field experiment in Chile showed that some lines of coastal lowland self-pollinated (CLS) quinoa had higher yield and seed size than the commercial cultivar Regalona, even under reduced irrigation. Proximal sensing methods, such as thermal and hyperspectral imaging, were used to estimate plant water use and differences in photosynthesis among the lines.

Summary: This study investigates the vernalization sensitivity and phenotypic characteristics of barley in order to adapt to future climate change. The results show that the vernalization response in barley is mainly concentrated in the phase before stem elongation, and is influenced by multiple major genes. Additionally, the duration of the late reproductive phase is also affected by other genes.

Summary: This study investigates the potential of Spanish germplasm for creating hybrids suitable for southern Europe, an untapped region for hybrid barley. A total of 140 locally adapted, advanced breeding lines from a Spanish breeding program were examined to expand the germplasm options for hybrid barley development. Through field trials and genomic predictions, lines with high general combining ability were identified for potential two-way hybrid production. The presence of brittle mutations in hybrid combinations, discovered through field trials, underscored the need for further research on heterotic patterns and proper management of brittle genes to broaden the germplasm pool for hybrid barley breeding.

Summary: In this study, a total of 261 barley accessions were phenotyped for culm diameter and culm wall thickness using an image analysis-based protocol. Genome-wide association studies revealed 192 quantitative trait loci (QTLs) associated with these traits, including 21 loci that impact lodging without affecting plant height. This research provides insights into the genetic control of culm morphology in barley and highlights the potential for improving lodging resistance and yield stability.

Summary: This study proposes a crop pangenome approach using individual cultivar assemblies to access conserved genes more easily. However, the variability in genome content and inconsistent identifiers have hindered exploration. To overcome these challenges, the concept of pangenes is introduced to summarize a species coding potential and link back to original annotations. The protocol get_pangenes utilizes whole genome alignments to identify syntenic gene models based on coordinate overlaps. Benchmark tests with both small and large plant genomes demonstrate that pangenes accurately recapitulate phylogeny-based orthologies and generate complete soft-core gene sets.
