Organization of actin filaments in regenerating and outgrowing subprotoplasts from pollen tubes ofNicotiana tabacum L.

abstract：MAIN CONCLUSIONS:Exogenously applied GR24 affected somatic embryo formation and morphogenesis of strigolactone-deficient tomato mutant through cross-talk with auxins and cytokinins indicating involvement of SLs in the embryogenic process. Strigolactones (SLs) mediate the regulation of plant responses to the environment...
