Table 3 The sex-linked region and proportion on sex chromosomes of willows in Vetrix clade.

From: The male-heterogametic sex determination system on chromosome 15 of Salix triandra and Salix arbutifolia reveals ancestral male heterogamety and subsequent turnover events in the genus Salix

Species

Sex/reference chromosome size (Mb)

Sex linked regions (Mb) and proportion on sex chromosomes

Salix arbutifolia

13.3 (Ref Salix purpurea v5.1, chromosome 15Z)

3.33 (24.9%)

Salix triandra

13.3 (Ref Salix purpurea v5.1, chromosome 15Z)

2.80 (20.9%)

Salix purpurea

15.7 (Ref Salix purpurea v5.1, chromosome 15W)

6.7 (42.7%)*

Salix purpurea

13.3 (Ref Salix purpurea v5.1, chromosome 15Z)

4.4 (33.1%)*

Salix polyclona

13.3 (Ref Salix purpurea, v5.1, chromosome 15Z)

4.68 (35.2 %)*

  1. Asterisk indicated that the proportion of SLR on sex chromosome was significantly different from Salix triandra and Salix arbutifolia according to ANOVA (p < 0.01).
