PHOTOPERIOD-1 homoeologous gene copies play a pivotal role in regulation of flowering time in wheat. Here, we show that their influence also extends to spike and shoot architecture and even impacts root development. The sequence diversity of three homoeologous copies of the PHOTOPERIOD-1 gene in European winter wheat was analyzed by Oxford Nanopore amplicon-based multiplex sequencing and molecular markers in a panel of 194 cultivars representing breeding progress over the past 5 decades.

- Common beans are essential for global food security, providing affordable protein and nutrients, but their genetic traits are not fully understood.
- The study identified 62 quantitative trait loci (QTL) linked to 16 important traits by examining a diverse panel of 200 bean genotypes using targeted genotyping-by-sequencing.
- Findings suggest major candidate genes related to key traits, including yield and seed quality, and highlight the potential for developing new varieties, although further validation in various environments is needed.
