| 摘要 |
<p>The invention features a substantially pure preparation of a nucleic acid encoding a HY4 or a HY4-related gene. The invention further features transgenic plants encoding a HY4 gene having a shorter stem than substantially homozygous wild type nontransgenic plants; and, transgenic plants comprising complementary HY4 sequences having a longer stem than substantially homozygous wild type nontransgenic plants.</p> |
