Gene expression, a case of regulation Expression of genes is regulated on multiple levels. Well known of these are the transcription factors, gene on/off switches. In addition, accessibility of the DNA determines if a gene can be transcribed or not. Moreover, there is regulation at the RNA level. Determining if and which part of theContinue reading “Gene expression, a case of regulation”

Gene editing via grafting
Gene editing via grafting Something we cannot ignore is our need for better plants. Plants that can deal better with extremes, like drought, heat, or salt. Plants that are better protected against pests. That have a higher yield. That are more nutritious. A whole shopping list. And rather yesterday than today. Techniques like gene editingContinue reading “Gene editing via grafting”
Arrested development
Arrested development Plants procreate through a double fertilization. They don’t get twins, only one of the two sperm cells fertilizes an egg cell. The second sperm cell is needed for the fertilization of the central cell. To form the endosperm, tissue that supports the developing embryo in its growth and germination. Giving the endosperm anContinue reading “Arrested development”
Keeping the balance when submerged
Keeping the balance when submerged Plants, just like animals and humans need oxygen to survive. Normally this is no problem. As a by-product of photosynthesis, oxygen is freely available. But by flooding a plant is under water, no photosynthesis can take place resulting in a lack of oxygen. To survive such a submergence, plants switchContinue reading “Keeping the balance when submerged”
