Abstract excerpt
KEY MESSAGE: A key gene, BpSPL2, identified from male-sterile mutants of Betula platyphylla, was demonstrated to play a crucial role in regulating male inflorescence development. Pollen represents a significant allergen in birch (Betula platyphylla Suk.). Its male inflorescence develops over nearly one year and overwinters as uninucleate microspores. Therefore, elucidating the molecular basis of male sterility in...
