Download PDF Plants suffer environmental and physiological stresses throughout their lives. Research has found that upregulating the production of chlorophyll at key times can boost productivity. CPM reports. Structurally the chloroplasts which house chlorophyll are architectural masterpieces. By Lucy de la Pasture The one thing all cropping systems have in common is that they’re harvesting light. Photosynthesis is the process of converting light energy to chemical energy which is stored in the bonds of plant sugars. This sugar becomes the building blocks for proteins, oils and carbohydrates that are harvested for food. One of the key aims of plant breeders is to elevate photosynthesis to produce more productive plants, explains Dr Nigel Grech, director of Unium BioScience. The faster the solar factory functions then more simple sugars (CHO – carbon, hydrogen and oxygen) are produced to form the building blocks of yield. What does the science say? Researchers have found that a leaf with 70 million cells houses five billion of the solar powerhouse structures, the chloroplasts. Each one of these contains approx 600 million molecules of chlorophyll. Together these trillions of chlorophyll molecules, all of which are bound to proteins of the photosynthetic membranes, harvest the sunlight. In fact…
