Do desert plants have the ability to use stored carbon when prolonged drought conditions prevent them from photosynthesizing? And if so, do desert areas change from being sinks of CO2 into being sources of CO2?

Desert plants, like all plants, can use storage compounds but without photosynthesizing they will not continue to grow. Many plants can change from sinks to sources of CO2 depending on their physiological state. This is not specific to desert plants, but rather all plants.
