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.
