WebMay 1, 2024 · Self-sterility in flowering plant species is commonly the result of genetic SI, which can act before fertilization (Hokanson and Hancock, 2000). However, in some plant species, the mechanisms of SI expression may occur after fertilization, which is indicative of LSI (Nuortila et al., 2006). WebS genes have been cloned and shown to encode glycoproteins with RNase activity. In self-pollinations, the RNase is internalized by receptors on the pollen tube surface. Once inside the pollen tube, the enzyme degrades RNAs essential to its further growth. From: self-sterility genes in A Dictionary of Genetics ». Subjects: Science and ... deshler law office
