In summary, OsMAX1a and OsMAX1e play an
important role in controlling rice tillering through
regulating the biosynthesis of SLs in rice. Remarkably,
the functions of MAX1 in rice are performed by a
number of different genes, which is different with the
single-gene mechanism in dicotyledonous plants.
Previously, the correlation between the function of
CYP711 proteins encoded by OsMAX1 and their
characteristics is also not clear. Therefore, this study is
important for revealing the underlying mechanisms of
how SLs influence rice tillering and elucidating the
relationship among plant type, the change of
composition and the biosynthesis of SLs in rice.
