Os07g0153600

The rice gene Os07g0153600 was reported as PROG1 in 2008^[1] by researchers from China.

Annotated Information

Figure 1 The transition from prostrate growth to erect growth. (a) Wild rice (O. rufipogon). (b) Cultivated rice (O. sativa). ^[1].

The PROG1 gene encodes a putative single Cys2-His2 zincfinger protein containing a highly conserved QALGGH motif specific to EPF zinc-finger proteins in plants and a leucine-rich motif that is similar to an EAR-like active repression domain at the C-terminal region
PROG1 controls prostrate growth of wild rice from Yuanjiang County in China.
PROG1 gene can decrease the number of primary and secondary branches, grain number and grain yield, and also suggest that the PROG1 gene was a key pleiotropic gene controlling plant architecture and yield-related traits in rice.

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.

Figure 4 Expression of PROG1 and prog1. ^[1].

The researchers detected GUS expression in the tiller base (Fig. 4b,c), leaf-sheath pulvinus (Fig. 4d,e) and lamina joint (Fig. 4f), but not in the root, leaf blade and culm.We also observed GFP activity and found that PROG1 was expressed strongly in the vascular bundles of the leaf-sheath pulvinus (Fig. 4g,h). Consistent with the expression patterns shown by GUS staining, they detected higher expression of PROG1 in the leafsheath pulvinus, tiller base and lamina joint by real-time quantitative PCR (Fig. 4i); these organs might directly respond to the development and maintenance of plant structure
