Comment
Functions in storage. This term should be used for tubers derived from roots (PO:0009005), as found in Cassava or sweet potato (Ipomoea batatas), not for tubers derived from branches (PO:0025073), as found in potatoes and yams. Use the term shoot axis tuber (PO:0004543), aerial tuber (PO:0004548), or subterranean tuber (PO:0004547) for tubers derived from branches. A tuberous root tuber may be distinguished from a tuber that is derived from a branch by the presence of a root cap (PO:0020123) early in development, or the presence of lateral roots (PO:0020121) or their remnants. Sometimes tuber roots bear vegetative buds (PO:0000058) like a tuber derived from a branch. A tuberous root tuber usually develops from a shoot-borne root (PO:0000042) or a lateral root (PO:0020121).
