Annotated Information

Function

Please input function information here. the gene encode a somatic embryogenesis（SERK-family）receptor-like protein kinase 1(OsSERK1) ,it also named BRI1-Associated receptor Kinase 1 (OsBAK1). The expression of OsBAK1changed important agricultural traits of rice such as plant height, leaf erectness, grain morphologic features, and disease resistance responses. A new rice variety with erect-leaf and normal reproduction can be generated simply by suppressing the expression level of OsBAK1.

Reduceing levels of OsBAK1 and decreasing sensitivity to BL will lead to semidwarfism in overall growth and result in abnormal growth patterns, especially in leaf development(Fig1)

Expression of OsSERK1 and in various organs of rice

Using a set of OsSERK1 primers (K-1; 5’AT(CT)AT(ATC)CATCG(AT)GATGTCAA3’ and K6-2; 5’CCATCTTGGGGCGTTCTGTG3’, where nucleotides in parentheses are a mixture). Actin (RAc-1; 5’AACTGGGATGATATGGAGAA3’, RAc-2; 5’CCTCCAATCCAGACACTGTA3’) was used as an internal control. The result showed that OsSERK1 was expressed in all organs and calli examined with different levels.Expression of OsSERK1 was relatively strong in a 1 DAP flower which contained a very early embryo, a leaf blade and a shoot apex. A callus on a regeneration medium with both cytokinin and auxin did not show significant change of the level of the OsSERK1expression in comparison to a callus on a callus-inducing medium.

(Poly(A)+RNAs isolated from the indicated organs were reversetranscribed and used as templates of the PCR. RT-PCR products were detected by Southern blot (OsSERK1) or ethidium bromide staining (actin). + and–indicate whether reverse transcriptase was add). (from reference ).

OsSERK genes were expressed in various organs but with some tissue specificity

The OsSERK1 promoter showed reporter gene activities in some specific tissues in a germinating seed, leaf and root, but not in a developing embryo. This promoter activity suggests that OsSERK1 may have roles in non-embryonic tissues rather than in the embryo.OsSERK1 might also be involved in signaling of or response to phytohormones in these tissues.
