⛅️ When we look at the clouds, we rarely think about life, but dream ourselves away into our own world of imagination. Suddenly, I'm telling you about an ocean in the sky where life is spread out. What lives in the clouds? Birds? Insects? Angels? Probably not. So high up, in the harsh conditions of cold and radiation, there is only very special life. I will now open your eyes to the fantastic world of microorganisms.

🦠 One of these many microorganisms is Pseudomonas syringae, a plant pathogen. It likes to live on and in plants and has a special trick to attack them. The bacterium forms a structure on its surface that acts as an ice nucleus, causing water above the freezing point to freeze. This means that ice crystals form more quickly at low temperatures, damaging the plant tissue and making it more accessible to the bacteria.

❄️ Many microorganisms, such as bacteria and fungi, are transported into the upper layers of the atmosphere by atmospheric buoyancy and strong winds. Some species have adapted to survive these conditions. The ability of Pseudomonas syringae to form ice crystals even influences cloud formation and precipitation. In this way, microorganisms not only influence the weather but also reach new places, encountering new plants and new genes.

🧬 Bacteria are an important factor in horizontal gene transfer. This means the direct transfer of genes to other life forms without reproduction, for example, from bacteria to animals and plants and vice versa. In very rare cases, this even influences the germ line and thus the evolution of more complex species.

♻️ Microorganisms are often only visible to us when they cause disease. However, they play a crucial role in our ecosystem. Infected plants, for example, are made accessible to other living creatures.

🌍 In other words, countless highly complex processes take place, influenced by the dynamics between life and climate - above our heads, under our feet, and within us.
