Who discovered that morphogenesis in culture medium is controlled by hormones

Options

A. Muir et al
B. Vasil and Hilderbrandt
C. Skoog and Miler
D. Helperin and Wetherell.

Answer

**Step-by-Step Text Solution:**

1. **Understanding Morphogenesis**: Morphogenesis refers to the biological process that causes an organism to develop its shape. In plants, this involves the differentiation of tissues into structures such as roots and shoots.

2. **Role of Hormones**: In plant biology, hormones play a crucial role in regulating growth and development. Auxins, for example, are a class of hormones that influence various aspects of plant growth, including root formation.

3. **Research on Morphogenesis**: The question asks about the discovery related to morphogenesis in culture media and its control by hormones. This research is significant in understanding how plants can be manipulated for growth in laboratory settings.

4. **Identifying the Scientists**: Several scientists have contributed to the understanding of morphogenesis in culture media. The options provided include Muir et al, Wessel and Hildebrandt, Skoug and Miller, and Halperin and Wetherin.

5. **Key Discovery**: The specific discovery that morphogenesis in culture medium is controlled by hormones was made by Skoug and Miller. They found that the addition of auxin to culture media stimulated root formation, even when root initiation was otherwise inhibited.

6. **Conclusion**: Based on the findings of Skoug and Miller, the answer to the question is that they discovered the control of morphogenesis in culture medium by hormones.

**Final Answer**: Skoug and Miller.
