In some RCBr plants, however, a mutation disrupts the anthocyanin production pathway and leads to green stems with no purple color. Plants use glucose as food for energy and as a building block for growing. Chemistry and Biochemistry of Plant Pigments Trevor Walworth Goodwin Snippet view - 1976. Chlorophyll is one of the main pigment in green plants. Cadmium concentrations in drinking water supplies are typically less than 1 microgram per liter (μg/L) or 1 part per billion (ppb) (ATSDR 1999). All these pigments stimulate the process of chemical reactions by reflecting the wavelengths. Light is collected by antenna pigments, symbolized as funnels and conducted to the reaction center pigments (P680 in PS II and P700 in PS I, in both cases chlorophyll a). may bear healthy and diseased tubers, while plants that show no signs of the disease may sometimes produce diseased tubers. The four main pigment components of plant leaves are chlorophyll a, chlorophyll b, carotene, and xanthophyll. These plants lost, or never acquired, genes for the synthesis of other plant pigments. Before the beginning of the modern era, the natural organic pigments were considered as an important part of the historical pigments. The major classes of plant pigments, with the exception of the chlorophylls, are reviewed here.
