Summary: This study introduces a new pipeline for conducting associative transcriptomics studies in Brassica oleracea. By focusing on flowering time as an example trait, it sheds light on the genetic basis of vernalization response in B. oleracea through associative transcriptomics, confirming it as a complex G x E trait. Candidate genes identified include miR172D and BoFLC.C2, which could potentially aid marker-based breeding efforts for B. oleracea with more synchronous heading dates and improved yields.

Summary: This study identified a major QTL capable of delaying blooming date in peach by increasing heat requirement. A genetic variant (pet DEL) in the PETALOSA gene was found to be strictly associated with this QTL, affecting both flower morphology and flowering time. Analysis on segregating genome-edited tobacco plants further confirmed the potential ability of PET variations to delay flowering time.

Summary: By utilizing SSR and SLAF-seq technologies, this study successfully mapped QTLs for flowering time in rapeseed and identified three target intervals. A total of 186 genes with genetic variations, including 14 related to flowering time pathways, were found in these intervals. Development of six InDel markers linked to flowering time indicates the credibility of the results for further genetic studies in Brassica napus L.

Summary: This study found that changes in flowering time in domesticated pea are controlled by four loci, including apparent gain-of-function variants of three florigen genes. This suggests a conserved route to reduced photoperiod sensitivity and early phenology in temperate pulses.

Summary: Cauliflower is an important vegetable crop globally, but its production is constrained by destructive fungal diseases like downy mildew. Developing resistant varieties through molecular breeding is crucial for sustainable cauliflower production. Identifying novel resistant resources and mapping resistance QTLs are essential for developing durable resistant cultivars.

Summary: Allelic variation in genes controlling the vernalisation requirement and photoperiod response determines the adaptation of wheat to different environmental conditions. This study screened a Spanish spelt wheat collection using gene-specific molecular markers and found significant differences in heading date between different allelic combinations. Genetic diversity analysis using SSR markers showed that spelt wheat is genetically distinct from commercial bread wheat. Knowledge of these genes and genetic variability is important for spelt wheat breeding programs.

Summary: This study aimed to identify the genomic regions associated with phenology in barley germplasm representative of breeding and production in the Southern Cone of South America. By conducting multiple field experiments, QTL were detected for multiple phenology traits in multiple environments. These findings provide insights into phenology in barley in temperate regions and can guide future research.

Summary: This study focused on flowering time in Brassica napus and identified two QTLs on chromosome A02, with one containing an important flowering gene. The constructed near-isogenic line flowered significantly earlier than the late flowering parent, providing potential for breeding superior maturity in B. napus varieties.

Summary: Turnip yellows virus (TuYV) is transmitted by aphids and causes yield losses in oilseed rape and vegetable brassicas. Resistance to TuYV has been identified and mapped in the diploid progenitor species of OSR, Brassica rapa and Brassica oleracea, with QTLs located on chromosomes A02, A06, and C05. The discovery of these new resistance QTLs provides opportunities for developing varieties with enhanced resistance to TuYV.

Summary: Detection of morphological stress symptoms through 3D examination of plants is a cost-efficient way to prevent yield losses and ensure product quality in agriculture and horticulture. The relationship between morphological and physiological plant responses to salinity stress needs further investigation. The study showed that morphological changes in leaf dimensions can serve as indicators for physiological responses in leaves under salinity stress.

Summary: Photosynthetic light response curve parameters are important for understanding the variation in photosynthetic traits, leaf acclimation status, carbon uptake, and plant productivity among different species. In this study, we analyzed the net photosynthetic light response curves and leaf traits of four amaranth species and found that maximum gross photosynthetic rate and leaf traits were correlated with plant productivity. We also observed that A. hybridus and A. cruentus had higher photosynthetic rates and light use efficiency compared to A. dubius and A. hypochondriacus. These findings highlight the importance of leaf photosynthetic characteristics and other leaf traits in determining plant productivity in amaranths.

Summary: One-dimensional light models using the Beer-Lambert equation are simple and robust for estimating light interception in homogeneous canopies, while functional-structural plant models are more complex but powerful in capturing light-plant interactions in heterogeneous canopies. Trade-offs between simplicity and accuracy need to be considered when modeling canopies with spatial heterogeneity. Including ray tracing in estimating the light extinction coefficient can improve accuracy in predicting long-term processes.
