Os01g0670800

The rice Os01g0670800 was reported as OsETTIN2 in 2014 by researchers from Japan.

Annotated Information

Gene Symbol

• Os01g0670800 <=> OsETTIN2,ETTIN2,OsETT2,ETT2

Function

• The rice OsETTIN2 genes promote awn development in rice.
• OsETTIN2 is involved in awn development in rice.
• DL and OsETT2 act independently in awn formation, and that either gene alone is not sufficient for awn development.
• The researchers hypothesize that loss of expression of OsETT2 in the awn primordium is probably associated with the failure of awn formation in japonica strains.

Expression

• OsETT2 is expressed in some parts of spikelet organs, such as the lemma, palea and carpel, we focused on OsETT2 expression in the developing awn.
• In Kasalath, OsETT2 was expressed in the putative awn primordium at the top of the lemma (Figure 6g).
• Subsequently, OsETT2 was expressed in both epidermal and sub-epidermal tissues in the elongating awns, in addition to provascular tissues (Figure 6h).
• In contrast to Kasalath, OsETT2 transcripts were not detected in the awn primordium of Nipponbare or T65, except for the provascular bundle (Figure 6i,j).
