In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green colour of leaves, chlorotic leaves are pale, yellow, or yellow-white. The affected plant has little or no ability to manufacture carbohydrates through photosynthesis and may die unless the cause of its chlorophyll insufficiency is treated, although some chlorotic plants, such as the albino Arabidopsis thaliana mutant ppi2 are viable if supplied with exogenous sucrose.


Chlorosis is derived from the word Chloris or from the Greek Khloros meaning "greenish-yellow," "pale green," "pale," "pallid" or "fresh".
