Figure 2From: Medicago truncatula contains a second gene encoding a plastid located glutamine synthetase exclusively expressed in developing seedsExon/intron organization of the two Medicago truncatula GS2 genes. Exons are numbered and represented by dark gray vertical boxes. The two MtGS2b alternatively spliced transcripts are shown, highlighting the retention of the first intron in the MtGS2b-α transcript. The start (ATG) and the stop codon (TAA) are indicated.Back to article page
