Gene Expression Analysis of Alfalfa Seedlings Response to Acid-Aluminum

Figure 4

The percentages of expression patterns for differentially expressed genes. The percentages of expression patterns for the 3926 differentially expressed genes were shown in the pie chart. Basically, they were divided into nine types: (1) “sr” meant specifically expressing in roots; (2) “sl” meant specifically expressing in leaves; (3) “ss” meant specifically expressing in stems; (4) “r&l” indicated genes expressed in roots and leaves; (5) “r&s” indicated genes expressed in roots and stems; (6) “s&l” indicated genes expressed in stems and leaves; (7) “r&s&l” indicated genes expressed in roots, stems, and leaves; (8) “other” indicated genes expressed in other plant tissues; (9) “unknown” indicated genes which cannot identify their expression patterns in NCBI databases.
