Project description:Transposable elements (TEs) are genomic parasites that constitute the most abundant portions of higher plant genomes. However, whether TE selection occurred during crop domestication remains unknown. HUO is active under normal growth conditions, present at low copy numbers, inserts preferentially into regions capable of transcription, but absent in almost all modern varieties, indicating its removal during rice domestication and modern rice breeding. HUO triggers genomic immunity and dramatically alters genome-wide methylation levels and small RNA biogenesis, as well as global gene expression. Its presence specifically affects agronomic traits by decreasing yield performance and disease resistance but enhancing salt tolerance, which mechanistically explains its domestication removal. Thus, our study reveals a unique retrotransposon as a negative target for maintaining genetic and epigenetic stability during crop domestication and selection.

Project description:Improving the yield by modifying plant architecture is key to progressive crop domestication. Here, we show that a 110-kb deletion on the short arm of chromosome 7 promotes the critical transition from semi-prostrate growth and low yield in wild rice (Oryza rufipogon), to erect growth and high yield in Asian cultivated rice (O. sativa). The microdeletion harbors a tandem repeat of seven putative Cys2-His2 zinc-finger genes. Three of these genes regulate the plant architecture in O. rufipogon and are closely linked to the previously identified PROSTRATE GROWTH 1 (PROG1) gene. Therefore, we refer to this locus as RICE PLANT ARCHITECTURE DOMESTICATION (RPAD). Furthermore, a similar but independent 113-kb deletion was detected at the RPAD locus in African cultivated rice. These results indicate that the deletions, coupled with the loss of a tandem repeat of zinc-finger genes, drove the parallel domestication of plant architecture in Asian and African rice.
