Cucumber seeds contain enzymes that break down plant growth hormones called gibberellins. One enzyme, CsGA3ox5, helps convert gibberellins into inactive forms. Another enzyme, CsGA1ox/ds, not only breaks down gibberellins but also changes them into different active forms. By modifying three specific amino acids in CsGA1ox/ds, it can also produce active gibberellins. This discovery could help in understanding how plants regulate their growth and development.
