The consequences on tuber transcriptome of a short heat period during tuber development was investigated in this study with special regard to the development of secondary tuber growth. Plants were grown for 47 days in the greenhouse under ambient conditions (21°C/ 19°C, 16h light, 8h dark) before application of mild heat stress temperatures (29°C/27°C) to one group of plants for 7 days and a stress release period on control temperature for 2 more weeks until harvest. Leaves were sampled before the heat period, at the end of the heat period and at harvest, two weeks after stress release. Tuber samples were taken at harvest. Tubers grown at normal temperatures and exhibiting a normal growth phenotype were used as control. Tubers subjected to the heat treatment and exhibiting a second-growth phenotype (chain tubers) were grouped into primary (attached to stolon from plant) and secondary tubers (attached to stolon from primary tuber).
