Hormones play a crucial role both in plants and animals. As we all
known, hormones work through specific receptors in different organisms.
Therefore, the hormone interaction between plant and animal is an
interesting question worth discussing. Recently, food safety has become
a common topic concerned by consumers. A widely discussed rumor such as
“Fruit bulking agent is some human reproductive hormones” leads us to
consider whether animal hormones did regulate plant growth. Based on the
large amount of previous research, we demonstrated that animal hormones
did affect plant, such as steroid hormones for livestock feed could
regulate physiological processes in plant including flowering,
senescence and stress resistance after excreted into the environment.
Here, we summarize the previous studies and systematically discuss the
effects of animal hormones on plant growth and development.
