Control of a key transition from prostrate to erect growth in rice domestication
Abstract
The transition from the prostrate growth of ancestral wild rice (O. rufipogon Griff.) to the erect growth of Oryza sativa cultivars was one of the most critical events in rice domestication. This evolutionary step importantly improved plant architecture and increased grain yield. Here we find that prostrate growth of wild rice from Yuanjiang County in China is controlled by a semi-dominant gene, PROG1 (PROSTRATE GROWTH 1), on chromosome 7 that encodes a single Cys(2)-His(2) zinc-finger protein. prog1 variants identified in O. sativa disrupt the prog1 function and inactivate prog1 expression, leading to erect growth, greater grain number and higher grain yield in cultivated rice. Sequence comparison shows that 182 varieties of cultivated rice, including 87 indica and 95 japonica cultivars from 17 countries, carry identical mutations in the prog1 coding region that may have become fixed during rice domestication.

PROG1 and LPA1 are other genes that regulate tiller angle, and both encode putative zinc finger transcription factors with C-terminal EAR-like repression domains.
“Other genes that regulate tiller angle are PROSTRATE GROWTH1 (PROG1; Tan et al., 2008) and LOOSE PLANT ARCHITECTURE 1 (LPA1; Wu et al., 2013). Both genes encode putative zinc finger transcription factors with C-terminal EAR-like repression domains.”

The tiller base in the prog1 mutant shows asymmetric growth due to a higher cell number on the lower side of the tiller base.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
