Hydrogen Sulfide Hastens New Leaf Growth

Hydrogen sulfide (H2S) is a gas with a distinctive rotten egg smell that is widely found in the environment from volcanoes, sulfur springs, undersea vents, swamps, municipal sewers, and in crude petroleum and natural gas (1). H2S is toxic at high concentrations, but at very small amounts, it can help plants and our bodies in many ways, including the improvement of plant germination and drought resistance, protection against cardiovascular diseases, and stimulation of memory (2-9).

Maximizing Gibberellic Acid’s Efficiency to Increase Growth

Gibberellic acid (GA3) is a plant hormone that was first isolated from the fungus Gibberella in Japan in the 1930s. It was found to promote plant growth activity.  Gibberellic acid has since been isolated from a variety of different plant types, ranging from beans to tobacco.

Common Cations on DNA Degradation

The process of DNA degradation is important to many scientific studies. Heat treatment is the standard procedure used to degrade genetic material by heating DNA-containing media past the DNA melting temperature
