3.4 Repeat annotation
We identified a total of 340.4 Mb of repeats (62.1 % of the genome) in
the Chinese walnut genome, of which ~62.42 % were
transposable elements (TEs) (Table 1; Table 2). The most abundant
repetitive sequences were long terminal repeat retrotransposons
(LTR-RTs), which accounted for 41.2 % of the assembled genome (Table
2), followed by LINE (long interspersed nuclear element, 12.22 %), DNA
(Class II TEs, 8.96 %), and SINE (short interspersed nuclear element,
0.01 %) (Table 2).
