Low temperatures still above the freezing point help to produce anthocyanin, which produces a bright red color. Why leaves change color. In one case, electrons that are energized when light strikes the chlorophyll molecule can be dumped onto oxygen molecules, creating a type of new type of oxygen known as superoxide (O2-, essentially oxygen with an extra negative charge). Splotches on a wide leaf with 'Opal'. Scales cannot fly; therefore, dispersal depends on the movement of crawlers.

I also found a host of other plants that were just as tough and lit up the north and northeast borders of against my house. Lower cells still with chloroplasts. As you go from zeaxanthin to violaxanthin, notice how the ring structures each gain an oxygen. Figure 3 shows the absorption spectrum for chlorophyll and carotenoids.
Note that the conversion involves adding an oxygen molecule to each of the two six-sided rings on either side of the zeaxanthin, a process known as de-epoxidation. Once the weather becomes dry and the leaves mature, spread of the disease will end and the tree will replace lost leaves with new growth.

Anthracnose is not a significant threat to the health of the tree and doesn't require treatment in most cases. When this bright light hits the leaf, it causes an imbalance between energy capture (the conversion of light energy into chemical energy) and energy utilization (the making of sugars in photosynthesis).
