Pears are an important fruit crop in the temperate climate region. Their cultivation by commercial growers or home gardeners remains challenging due to different biotic and abiotic threats. One of the most important diseases of pear is fire blight, a bacterial disease caused by Erwinia amylovora (Burrill) Winslow et al. This harmful disease can only be effectively controlled with antibiotics, severe pruning of affected parts,...

Most cultivars of the domesticated apple ( Malus domestica Borkh.) are susceptible to fire blight, caused by the bacterium, Erwinia amylovora . Although some moderately resistance QTL have been identified in apple, the major QTL have been found in wild apple species. Resistance to fire blight in Malus is, however, strain-dependent with proven gene-for-gene relationships. The QTL of three wild Malus species, namely Malus florib...

Key message 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. Abstract 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...
