Here some experiments to find the function of PROG1. They further developed a near-isogenic line, NIL(PROG1), that contained a very short PROG1chromosomal segment from wild rice in the Teqing genetic background and characterized the plant architecture (Fig. 1). During the early seedling stage, both tiller bud formation and tiller outgrowth in NIL(PROG1) were earlier than that in Teqing (Fig. 1a,b). After the tillering stage, NIL(PROG1)produced many tillers, but Teqing produced very few (Fig. 1c,d,f). Furthermore, NIL(PROG1) showed increased tiller spread with a wider tiller angle, whereas Teqing had a compact plant architecture with a narrower tiller angle (Fig. 1c,e). These results show that NIL(PROG1) possesses plant architecture similar to that of wild rice, including a prostrate growth (a wider tiller angle) and many tillers, suggesting that PROG1 may be a key domestication gene responsible for plant architecture.(Jin et al., 2008).

Genetic linkage analysis within 246 F2individuals derived from the cross between YIL18 and Teqing showed that prostrate growth was
 
completely associated with a marked decrease of GNP and controlled by a single semi-dominant gene,PROG1(PROSTATE GROWTH 1), located between SSR markers RM298 and RM481 on short arm of chromosome 7 (Fig. 3a). Using a total of 3,600 recessive homozygote
 
plants with erect growth from the F2population, we further delimited prog1 within an 8.8-kb region between the pr5 and pr7 markers
 
(Fig. 3b). Within this region, there is only one hypothetical gene (LOC_Os07g05900) in the Nipponbare genome (the TIGR Rice
 
Genome Annotation Database)9 (Fig. 3c). One positive BAC clone (YJ0710308) covering this region was isolated from genomic BAC
 
library of YJCWR (Fig. 3d). We screened the YJ0710308 subclone library and identified two subclones, pPROG1-1 and pPROG1-2,
 
containing the entire O. rufipogonLOC_Os07g05900 with 596-bp and 2,914-bp 5¢-flanking regions, respectively (Fig. 3e)(Jin et al., 2008).

PROG1 encoding a 167 amino acid composition of zinc finger transcription factors, mainly in the axillary bud separatist group.In the gene encoding between wild rice and cultivated rice in hainan area has a base mutation amino acid replacement, speculated that the amino acid substitution in the process of artificial domestication is selected (Jin et al., 2008).

PROG1 is predominantly expressed in the axillary meristems, the site of tiller bud formation. Rice transformation experiments demonstrate that artificial selection of an amino acid substitution in the PROG1 protein during domestication led to the transition from the plant architecture of wild rice(O.rufipogon) to that of domesticated rice(O.sativa).

  • PROG1 controls prostrate growth of wild rice from Yuanjiang County in China.
