Light in Tuberisation

The critical role of light in the tuberisation of sweet potato (Ipomea
batatas) has been well documented. Exposure of tuberising roots
to sunlight inhibits tuber growth while stems, which develop in the
dark leads to the formation of stem tubers. The mechanism of such
light effects, however, remains obscure. This paper reports on
conditions, which result in the formation of stem tubers in cassava
(Manihot esculent, Crantz) and suggests how it could be used
as a model to elucidate the effects of light on gene expression on
tuberising systems.
