Marchantia also reproduces asexually, producing small cup shaped ‘splash cups’ with clusters of cells (gemmae) at the base. These can be ejected by rain drops and are capable of producing new gametophytes if the end up in a favorable location. WebAbstract In vegetative reproduction of Marchantia polymorpha (M. polymorpha), propagules, called gemmae, are formed in gemma cups. Despite its significance for survival, control of gemma and gemma cup formation by environmental cues is not well understood. We show here that the number of gemmae formed in a gemma cup is a genetic trait. sulfate and alcohol free shampoo
