All introns, except for psbW-i2, are present either in the presequence-encoding regions or shortly upstream of them. The table includes accession numbers of partial gene sequences containing corresponding introns, intron length (in nucleotides), intron borders, AT- and T-content of introns, and intron phase. Nt position is the position downstream of which the intron is inserted into the corresponding mRNA or EST sequence (for the accession numbers of mRNAs and ESTs see Tables 1 and 2).
