Journal Article
A single gene underlies the dynamic evolution of poplar sex determination
2020
Overview
Although hundreds of plant lineages have independently evolved dioecy (that is, separation of the sexes), the underlying genetic basis remains largely elusive
1
. Here we show that diverse poplar species carry partial duplicates of the
ARABIDOPSIS RESPONSE REGULATOR 17
(
ARR17
) orthologue in the male-specific region of the Y chromosome. These duplicates give rise to small RNAs apparently causing male-specific DNA methylation and silencing of the
ARR17
gene. CRISPR–Cas9-induced mutations demonstrate that
ARR17
functions as a sex switch, triggering female development when on and male development when off. Despite repeated turnover events, including a transition from the XY system to a ZW system, the sex-specific regulation of
ARR17
is conserved across the poplar genus and probably beyond. Our data reveal how a single-gene-based mechanism of dioecy can enable highly dynamic sex-linked regions and contribute to maintaining recombination and integrity of sex chromosomes.
Populus
has young sex chromosomes despite ancient dioecy. This study shows that the
ARR17
gene functions as a sex switch, triggering female development when on and male development when off. This single-gene system enables dynamic evolution of poplar sex chromosomes.
