Pre-harvest sprouting (PHS) often results in reduced grain yield and quality and is a major problem in cereal production. Improved seed dormancy would inhibit PHS. Here we show that seed-specific overexpression of two SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE (SPL) genes SPL12 and IPA1 enhances seed dormancy and inhibits PHS without noticeable effects on shoot architecture in rice. https://missouriquiltcoes.shop/product-category/sew-in-non-woven/
