Expression profile of SP and SPH genes during different developmental stages. Gene expression levels are represented by red (higher) and blue (lower) boxes. Genes that express only in male silkworm during metamorphosis are marked by a rectangle. The columns represents twenty different sample time points: day 3, 4, 5, 6, 7 of the fifth instar, start of wandering, 13 different times after wandering: 12 hour, 24 hours, 36 hours, 48 hours, 60 hours, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days and adult.Word "mix" in the column name represents that the sample came from both gender; word "m" in the column name represents that the sample came from male silkworm; word "f" in the column name represents that the sample came from female silkworm.
