Spatial expression patterns of the silkworm ABC genes in multiple larval tissues on day 3 of fifth instar. Normalized microarray data (GSE17571) for gene expression in multiple tissues of silkworm larvae on day 3 of fifth instar was used to survey tissue-specific expression of ABC genes. ABC transporter gene was considered to be expressed if its normalized intensity value exceeded 0. The expression levels are illustrated by seven grade color scales representing relative expression levels of -3, -2, -1, 0, 1, 2 and 3. Red color represent positive; black color represent zero; green color represent negative; A/MSG anterior/middle silk gland, PSG posterior silk gland.
