Genomic insight into domestication of rubber tree

<p>we upgraded H. brasiliensis genome assembly (contig N50 of 11.21 megabases), presented a map of genome variations by resequencing 335 accessions and revealed domestication-related molecular signals and a major domestication trait, the higher number of laticifer rings. HbPSK5, encoding the small-peptide hormone phytosulfokine (PSK), was a key domestication gene. It was closely associated with the major domestication trait by positively controlling laticifer differentiation from vascular cambia. The transcriptional activation of HbPSK5 by MYC members linked JA signaling to PSK signaling in enhancing laticifer formation.</p> <p>cite:https://www.nature.com/articles/s41467-023-40304-y</p>
